地下室台階

從南側停車場沿著往海邊的小徑，下到石頭階梯底下地下一樓的平台，往北走到平台邊緣，從一 個容易往下攀爬的岩溝，下到地下二樓的平台(旁邊為水塘），有時岩溝處會有固定繩索。介於地 下一樓與地下二樓兩平台高低之間的白色岩壁就是地下室台階，有不少短路線與抱石路線，越往 海邊路線越簡單，還有幾處可玩跳水的地方。
From the south parking lot, descend the fisherman’s trail to the stone staircase, walk north across the main level of the Back Door B1, and find a groove at the north edge of B1's main platform. Climb down this groove, which sometimes has a fixed rope, to the Basement level near a pond. Several short climbs and boulder problems are found on the white face below the B1 level, on the wall that forms the step between B1 and the Basement. There are more easy climbs and some cliff-diving exit points to the left (toward the sea)
