27 Hairpin Turns and a Tunnel Hidden in the Mountain: Lysevegen, the Stairway to the Sky from the Bottom of the Fjord

A Village at the Bottom of a Fjord, with Only One Way Out—Up

If you arrive in Lysebotn by ferry or on foot, this small village tucked at the very head of the Lysefjord, you’ll find yourself surrounded by nearly vertical fjord walls, with a skyline that feels almost oppressive when you look up. This is the trailhead for Norway’s famous hiking landmark, the Kjerag Boulder (Kjeragbolten), drawing large numbers of hikers and BASE jumpers every year. But for cyclists, the real legend isn’t the mountain—it’s the road that connects the village to the outside world: Lysevegen (Norwegian for “The Lyse Road”), commonly known as the 27 hairpin bends of Lysebotn.

The very existence of this road is an engineering marvel: the entire road stretches about 29 kilometers, climbing over 900 meters from the fjord floor, which sits near sea level. Along the way, it includes 27 hairpin bends, one of which is hidden entirely inside a mountain tunnel over a kilometer long—meaning you’ll complete a full hairpin turn inside the tunnel, with darkness, echoes, and relentless gradient. It’s a cycling experience rarely found anywhere in the world. The road wasn’t officially opened until 1984; before that, Lysebotn was a nearly isolated village reachable only by boat or on foot.

Before the road opened, Lysebotn’s residents and travelers relied entirely on fjord ferries to maintain contact with the outside world, and during rough winter seas, the village could lose contact for days at a time. This geographic isolation made the opening of Lysevegen a landmark achievement for the local community—a single road, for the first time, allowing a settlement at the bottom of a fjord to climb over the vertical fjord walls by land and connect to Norway’s inland road network. For this reason, from the moment it was born, this road was never just a “scenic route”; it carried the real significance of linking an isolated community to the outside world. This historical depth adds a layer of human weight to riding this road that goes beyond the scenery and the gradient numbers.

The road’s fame in the global cycling community owes much to aerial photography and time-lapse footage in the age of social media—when you view the entire road spiraling upward from above, the 27 hairpins look like contour lines brushed onto a vertical rock face by a painter. This visually striking imagery has made Lysevegen a recurring highlight of Nordic travel and cycling content on platforms like Instagram and YouTube, attracting more and more international riders to make the pilgrimage to take on the challenge.

Route Basic Information

The overall average gradient figure requires special explanation: Lysevegen’s terrain structure is highly unusual—the latter section includes a fairly long stretch that runs relatively gently across highland terrain to the finish service area. This gentle section drags down the “whole road” average gradient, making it look like only about 3%, which can seriously mislead riders planning the route for the first time. What truly determines the difficulty of this road is the steep climb that spirals up from the fjord floor, containing all 27 hairpin bends. This section has a significantly higher average gradient, estimated to fall close to the 9% range, with considerable fluctuation along the way—some bend sections may briefly approach or even exceed 10%. When planning your trip, be sure to assess your ability based on the difficulty of the “hairpin section,” rather than being misled by the overall average.

Section by Section: Three Completely Different Worlds

Section One: Warm-Up at the Bottom of the Fjord

Starting from Lysebotn village, the first few hundred meters follow the gentle terrain at the bottom of the fjord, with a relatively mild gradient. Though short, this stretch is a crucial moment for mental preparation—you can clearly see the zigzagging road spiraling up the rock face ahead, layer upon layer, like lines brushed onto a vertical cliff by a painter. Simply measuring the climb ahead with your eyes is enough to take your breath away.

Section Two: The Vertical Theater of 27 Hairpin Bends

This is the soul of the entire Lysevegen. The 27 hairpins are packed tightly onto the nearly vertical fjord wall, one of the few road engineering cases in the world that crams so many bends into such a limited horizontal distance. Around every bend, the view changes dramatically—you can clearly see the path you just rode winding below, and the fjord water gradually shrinks to a thin line as you gain altitude. This visual feedback of “constantly looking back at where you came from” is one of the most unique psychological experiences of Lysevegen compared to other famous climbs: on most long climbs, you can’t see the finish ahead or the start behind, but here both are clearly visible, constantly reminding you how high you’ve climbed and how much remains.

This visual feedback is a double-edged sword—for riders with strong willpower, watching the fjord water shrink below is a huge source of accomplishment, with every bend serving as tangible proof of progress. But for riders already nearing their physical limits, the visual pressure of “clearly seeing how many bends remain” can create additional psychological burden. Especially in the densely packed hairpin sections, looking up at the layers of switchbacks above can easily breed frustration—“so many more to go.” Many riders who have completed the climb recommend, in their shared experiences, that instead of constantly looking up to count how many bends remain, it’s better to focus on the cadence and breathing rhythm of “this one bend,” breaking down this long physical test into shorter psychological segments. This approach is easier to sustain than facing the macro pressure of the entire road at once.

It’s worth noting that the bend numbers on this road are clearly marked in local Norwegian signage and some guide information—numbered from 1 all the way to 27. This “countdown” style visual cue has, to some extent, become a unique ritual of the road. Many riders who have completed it make a point of stopping to take photos beside each bend number, turning the entire challenge into a visual journey that can be reviewed frame by frame.

Section Three: The Hairpin Inside the Tunnel

This is Lysevegen’s globally famous signature feature—one of the 27 hairpin bends is placed entirely inside a mountain tunnel over a kilometer long. When you ride into the tunnel, the light instantly switches from natural to artificial, and the road maintains its dual challenge of gradient and curvature, but all visual reference points disappear, leaving only the arc of the tunnel walls and the lights ahead. This experience of turning a hairpin inside a dim tunnel is rare in road engineering worldwide, and it’s the segment riders most fondly recount in their ride reports—that absurd feeling of “they didn’t even spare you inside the tunnel” makes you both terrified and unable to keep from laughing.

Section Four: The Gentle Highland Finish

After emerging from the tunnel, the gradient gradually eases, opening into relatively expansive highland terrain. The final stretch follows gently rolling topography to the Øygardstølen service area at the finish—also the starting point for the Kjerag Boulder hiking trail, with parking and basic facilities. It’s an excellent rest and resupply point after completing Lysevegen, where you can also enjoy the expansive highland views and distant mountain ridges, forming a stark contrast with the vertical fjord terrain you just crossed.

Power and Pacing Estimates (Physical Model)

Because of Lysevegen’s unusual terrain structure, we provide two calculation methods for readers’ reference. Model formula:

P = (Fg + Fr + Fa) × v / Drivetrain efficiency

Fg = m × g × sin(arctan(gradient))      Gravity component
Fr = m × g × cos(arctan(gradient)) × Crr  Rolling resistance
Fa = 0.5 × ρ × CdA × v²              Air resistance

Parameter assumptions: rider weight 70 kg + bike and gear 9 kg (total 79 kg), g = 9.81 m/s², Crr ≈ 0.005, CdA ≈ 0.32 m², air density ρ ≈ 1.19 kg/m³, drivetrain efficiency 0.975.

Method One: Full 29 km, ~900 m elevation gain (average gradient ~3.1%)

Method Two: Hairpin steep section only (estimated ~8 km, ~700 m elevation gain, average gradient ~8.8%)

The hairpin section split in Method Two is an estimate based on terrain, not official precise segment data, provided only to help readers understand the gap between the “steep part” and the “full average.” These are physical model estimates that do not account for wind direction, changes in air resistance inside the tunnel, road surface variations, or differences in rider physique. Actual results vary from person to person. This article does not fabricate any professional rider’s record times or power data for this segment.

Seasonal Restrictions: A Road That Only Exists in Summer

Lysevegen is a thoroughly seasonal road—local information clearly states that the road is open only in summer, when the snow has melted and the surface is confirmed ice-free, and it closes due to heavy snow in winter. This means the time window for taking on this road is quite limited, typically concentrated in the summer months. The exact opening and closing dates fluctuate each year depending on snowfall and snowmelt conditions. Be sure to check the official announcement for the current year before departing; don’t rely on estimates from past years.

Even during the open season, highland weather can change abruptly—this area is close to the Kjerag mountains, which is higher-altitude terrain. Even in the Norwegian summer, temperatures at the summit are noticeably low, and the open highland terrain is subject to strong winds with no shelter. Riders arriving at the finish service area often feel a dramatic temperature difference compared to the bottom of the fjord. It’s recommended to carry sufficient layered warm clothing and a waterproof outer layer, as mountain rain and fog can appear at any time.

This temperature difference between the fjord floor and the highland finish is a climate feature of Lysevegen particularly worth mentioning. Because the fjord terrain is sheltered by the rock walls on both sides, combined with the moderating effect of the sea, temperatures at the bottom are usually relatively mild—in midsummer, there can even be a stuffy, enclosed feeling wrapped by the fjord walls. But as altitude increases, especially after emerging from the tunnel into the highland terrain, wind and temperature shift noticeably. Many riders mention in their shared experiences the contrast of “wearing short sleeves at the start and still being hot, then shivering cold at the finish.” This compressed vertical climate zone effect is a common feature of fjord-terrain roads, and when planning gear, be sure to account for this temperature difference rather than only referencing the departure point or a single weather station’s numbers.

Additionally, the temperature inside the tunnel may differ noticeably from the outside environment—mountain tunnels typically maintain a relatively stable, cooler temperature year-round, and without direct sunlight, even on a sunny summer day outside, you may feel a chill upon entering the tunnel. This is another small detail worth noting when planning your clothing adjustments and supplies.

A Taiwanese Rider’s Perspective: Putting 27 Hairpins into Your Coordinate System

Using climbs familiar to Taiwanese riders as a reference, the gradient intensity of Lysevegen’s steep hairpin section is similar to the middle section of the Wuling western approach, but because the terrain feels more vertical and the bends are denser, the actual riding experience is closer to some kind of “enhanced version” of the continuous hairpin section of Hehuan Mountain. If you count the full 29 kilometers, the length and elevation gain already exceed the entire Wuling western approach, making it a heavyweight long climb requiring solid fitness and resupply planning.

For Taiwanese riders, the most distinctive challenge of this road lies in psychological adjustment—most long climbs in Taiwan (such as Wuling) have a relatively sustained gradient that makes it easy to settle into a steady pacing rhythm. But Lysevegen’s structure of steep early, gentle late, plus the unique experience of unchanged gradient but vanished visual references inside the tunnel, disrupts the rhythm perception most people are used to. It’s recommended to understand this terrain characteristic in advance to avoid misjudging that you’re “almost done” during the hairpin section and easing up too early or surging too hard.

In terms of practical travel arrangements, Lysebotn itself, as an isolated village at the bottom of the fjord, has access logistics completely different from the road-trip logic Taiwanese riders are familiar with—besides the Lysevegen road itself, the other common way to arrive is by fjord ferry. This is also a method recommended in many cycling ride reports: take the ferry into the fjord one way, and challenge Lysevegen to climb out of the fjord the other way (or the reverse), allowing you to experience both the expansive views of fjord navigation and the physical challenge of road climbing. For specific ferry schedules, bicycle carriage regulations, and fees, be sure to refer to the latest official announcements from the ferry company, and don’t rely on potentially outdated schedule information found online.

For riders accustomed to Taiwan’s convenient scooter and car shuttle culture, this planning logic of “must rely on a ferry to reach the start” may require some psychological adjustment—unlike Wuling, where you can drive directly to the trailhead and depart at your leisure, Lysebotn’s geographic isolation means your entire itinerary’s schedule is largely dictated by ferry times rather than fully under your control. It’s recommended to do your homework in advance, factoring ferry arrival times, recovery buffer, and the time needed for the climb into your overall plan, to avoid having your rhythm disrupted by ferry connection issues.

Another practical consideration is resupply planning. Lysebotn village itself is small with limited commercial facilities, and while the Øygardstølen service area at the finish has basic amenities, its service scope and opening hours adjust with the season. It’s not wise to rely entirely on roadside resupply; it’s recommended to bring sufficient water and portable food, especially for riders planning to tackle the full 29 kilometers, as there are almost no other commercial resupply points along the way. This area is also a popular hub for hiking and extreme sports (Kjerag Boulder hiking and BASE jumping are both based here), and the finish service area can be quite crowded during peak season. If you’d prefer a quieter rest space, consider avoiding weekends or peak hours for hiking group activities.

Safety Reminders

• Special risks of riding inside the tunnel: The tunnel has dim lighting and pronounced echo effects. It’s recommended to equip front and rear lights and reflective accessories, turned on even during the day, to increase your visibility, and to be aware that vehicle drivers may need longer visual adaptation time inside the tunnel.
• Rockfall risk from fjord cliff terrain: Steep cliff roads carry a long-term rockfall hazard; watch for traces of fresh gravel accumulation on the road surface while riding.
• Strong winds and hypothermia on the highland terrain: The finish service area has open terrain with temperatures noticeably lower than the fjord floor; add warm layers immediately upon arrival.
• Seasonal closure: Be sure to confirm the current year’s opening dates before departing to avoid a wasted trip.
• Brake load on descents: Regardless of which direction you challenge, the steep hairpin sections place heavy demands on the braking system. Use intermittent braking to avoid sustained high temperatures causing brake fade.
• Signal and rescue in remote areas: Mobile phone signals may be unstable on some sections of the fjord floor and highland terrain; it’s recommended to ride with companions and inform others of your itinerary.
• It’s not advisable to race for personal records on this kind of visually stunning, distraction-prone road; safety always takes priority over performance.
• Self-sufficiency for mechanical issues and supplies: Commercial facilities along the way are limited; check that your tire repair tools, spare tubes, and basic repair kit are complete before departing, and carry sufficient water and portable food. Don’t expect to easily obtain support along the way.
• Differences between climbing and descending directions: Riding up from the fjord floor is a classic climbing challenge testing cardiovascular fitness and muscular endurance; if you choose the reverse direction, descending from the highland to the fjord floor, pay special attention to the high demands that continuous hairpin descents place on braking systems and bike-handling skills. The risk profiles of the two directions differ, so honestly assess your abilities and experience before choosing.

Conclusion: A Stairway to Heaven Blending Engineering Limits with Fjord Aesthetics

Lysevegen’s place in the hearts of cyclists worldwide rests not just on the eye-catching number 27 hairpins, but on how it compresses three completely different geographic scripts—“vertical fjord terrain,” “hairpin inside a tunnel,” and “highland finish”—into a single road of just 29 kilometers. When you emerge from that tunnel over a kilometer long, see the highland daylight again, and look back at the fjord wall you just spiraled up, the shock of “I actually climbed up from that village too small to see” will be one of the most unforgettable riding memories of your life.

Pre-trip key points:

1. Assess your ability based on the steep hairpin section, not the overall average gradient: The real challenge is concentrated in the 27-bend stretch.
2. Confirm the current year’s opening dates: It’s a seasonal road; check official announcements before departing.
3. Prepare tunnel-riding gear: Front and rear lights and reflective accessories are essential.
4. Bring layered warm clothing and waterproof gear: The temperature difference between the fjord floor and the highland finish can be significant.
5. Consider combining the ferry for a one-way itinerary: You can experience both fjord navigation and road climbing from two completely different perspectives.
6. Ride with companions and share your itinerary: Signal is unstable on some sections; build your own safety net.
7. Honestly assess your ability for the climbing or descending direction: Climbing tests your cardiovascular system; descending tests your handling and braking. Choose the direction that suits your experience level.

If Trollstigen’s 11 hairpins have left you wanting more, Lysevegen’s 27 bends and that tunnel hidden in the mountain will be the ultimate escalation on your Norwegian cycling grand tour checklist—this stairway from the bottom of a fjord to the clouds is worth planning a dedicated Nordic trip to conquer in person.

Interestingly, this road has also attracted attention from cycling endurance events and challenge activities. Some international rider communities spontaneously organize time trials or group rides centered on Lysevegen, treating the road as the grand finale of a Nordic cycling grand tour. Whether you come as a pilgrim checking off a “must-ride list” or are simply moved to set out by that aerial photo of 27 hairpins seen from above, this road will not disappoint—it proves, with almost exaggerated topographic drama, that road engineering can also be a breathtaking art form, and riding it is the most direct way to participate in that artistic performance yourself.
