Steep almost everywhere, it has an abundance of crags and cliffs, and high annual rainfall. There are no motor roads in; visitors either have a long walk, or a boat trip from Mallaig or Arnisdale. Once there, many people feel as if they're on an island.
The 1250 hectares of John Muir Trust land lie along Loch Hourn on the north east coast of the peninsula, within the Knoydart National Scenic Area. Li is a farm (run by a tenant) at one end, and Coire Dhorrcail is the biggest of the corries of Ladhar Bheinn. The SW boundary takes the 914 m (3000 ft) contour of Ladhar Bheinn, 1020m, thus including the mountain's summit ridge.
This part of Knoydart was the first land the John Muir Trust bought, in 1987. There had been almost total clearance of native trees, and most of the trust’s work since then has been to restore woodland, by new planting, and by giving natural regeneration a chance. This has involved reducing deer numbers, and making fenced enclosures to keep deer out. They are also maintaining the old stalkers' paths that cross the area.
