Really...best view for miles!!!

This is great fun, I've done both descents now, both north and south but neither climb, and I'm very happy about that. Would want an unloaded bike to clean the whole trail.

This area is also great for some technical trail running. Plenty of footpaths meander around the hills.

As you descend to this section to the viewpoint I've shared, please be aware that you have rocks and drops to descend that can be slippery when they are wet.

Steady climb with lovely views of the valley. Bothy is usually busy over weekends so if you're keen to stay there without company, head up midweek outside peak season. Otherwise, embrace the spirit of what you set out to do and share an evening with a fellow bothy fan!
