Stanley Ghyll Force is an 18-metre (roughly 60-foot) waterfall tucked into a narrow, 150-foot gorge in the Eskdale Valley of the Lake District, Cumbria.

The ravine's sheltered, humid walls support an exceptionally rich growth of mosses, liverworts, and ferns, earning the site designation as a Site of Special Scientific Interest.

In summer the gorge becomes almost tropical in appearance, widely regarded as one of the most beautiful waterfall settings in the Lake District.

The falls are reached via a moderate walk of around 30 minutes from the National Trust car park near Dalegarth Station on the Ravenglass & Eskdale Railway.

The path follows Stanley Ghyll Beck upstream through woodland before climbing a series of steps into the gorge. A viewing platform provides a dramatic perspective of the falls.

Footing throughout can be extremely slippery, and the trail is not recommended for young children or those with limited mobility.
