Safety information

Mostly good paths/sheep trods throughout. Some exposure (to the right only) on Fan Hir ridge. The returning path to finish from Llyn Y Fan Fawr is stony/technical in places. In poor viz, navigation and path choice can be difficult – with use of compass/map being important. But in good viz, geography of mountain guides you up and back. Escape routes to roads in north take you 40 mins (drive) from start.
