Southeast Cheung Chau boasts paths that wind around headlands and curl up and over hillsides, passing through woodland, and near to naturally sculpted giant boulders, once grand but now ruined houses, a couple of temples, a tiny nunnery, and cliffs dropping to the sea. The main trail here is rather fancifully named the Mini Great Wall, but you can find other less known yet still fascinating paths to explore.
Perhaps the easiest route to the southeast is the path south from Tung Wan beach, to smaller Kwun Yam Wan. Just above Kwun Yam Wan is a small, garish red temple - and above this are a couple of trail junctions in a small valley (Fa Peng valley, to me). From one of these junctions, steps lead uphill - towards the Mini Great Wall.
