Hoi Ha Road Second Climb from Ko Tong
This short, steep Sai Kung North ascent begins near 33 metres above sea level at Ko Tong and follows paved Hoi Ha Road north to a road high point near Pak Sha O Ha Yeung at roughly 182 metres. The verified canonical Strava mother segment is 1.77 kilometres. Its 462-point high-resolution stream reconstructs to about 170 metres of cumulative climbing, 27 metres of descent and roughly 150 metres of net gain, with no elevation-datum contamination. The first 600 metres climb steadily, a brief undulation appears around 700 to 900 metres, and the final 400 metres steepen markedly. Both dry-run and formal checks found only one suitable real child segment; because fewer than two pieces were available, the safe command retained the complete mother segment and did not omit the final 0.27 kilometres. Hoi Ha Road is rideable but not closed to traffic: keep left in single file, expect minibus 7, taxis, local vehicles, walkers and blind bends, and never turn onto cancelled or undesignated mountain-bike trails.

Route Overview
路線概述
海下路穿越西貢西郊野公園北部,連接北潭路一帶與海下村、海下灣。本線採用香港車友稱為 Hoi Ha 2nd Climb 的第二道核心爬坡:從高塘附近約海拔 33 公尺處出發,沿鋪裝海下路向北,在白沙澳下洋一帶約海拔 182 公尺的道路高點收尾。它不是整條海下路,也不含海下村至海岸公園的行人路或已取消的北潭—白沙澳越野單車徑。
香港社交公路單車路線資料明確指出,可沿北潭路接黃石方向,再轉海下路騎往海下;當地車友也把海下路列為常見運動騎乘道路。沿線遠離市區,但不是封閉賽道,會遇到 7 號專線小巴、的士、村民車輛與假日郊遊交通。路線短,卻在末段快速增陡,適合已具道路爬坡與低速操控經驗的騎士,而不適合以「郊野公園車少」為由放鬆警覺。
