Very nice bridge not for traffic though as it’s a single lane track with passing gaps for pedestrians.

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!
