White Hole is unique to the west coast of Portland, being an area of well-defined and deeply-incised zawns. The walls of the zawns are relatively short compared to the neighbouring Coastguard Cliffs, but have a set of good routes with an atmosphere that is out of all proportion to their size. The rock is solid, but also extremely rough and it can be a bit tough on finger skin. Many of the lines are climbed both as sport climbs and deep water solos.
Drive to Portland Bill and park by the lighthouse (fee). Walk westwards (right - looking out) next to a fence and above an old quarry for 200m. Turn right at the cliff top and follow the fence. The South Cliff is just below the top after 20m. Mirthmaid Zawn is the large square-cut prow further into the bay. It is reached by following the fence closely past a pipe, before dropping down onto a large rock platform. To reach Memories Zawn and the Faceache Area, continue from the large rock platform by scrambling up to the top of the Mirthmaid promontory. Move along a narrow cliff-top ledge that runs right (looking out) around a square-cut zawn to a narrow rift beneath the weird conglomerate rock bridge.
