At 948 metres, Pico do Príncipe is the highest point on the island and one of the more demanding hikes in West Africa. The trail climbs through multiple vegetation zones, from secondary forest near the park boundary to dense montane cloud forest near the top, where the trees are hung with moss and the air is cool and damp even on a clear day. The summit offers views across the whole island when cloud permits, which is not always.
The ascent takes a full day — most hikers start before dawn and return by late afternoon. The route is unmarked and requires a guide familiar with the current path, as windfall and erosion shift the trail seasonally. Contact the Fundação Príncipe in Santo António to arrange a guide. The climb is best attempted in the dry season (June–September) when the paths are less treacherous.
