One lovely thing about the Lake District is that it has so many of the features of the big world outside Cumbria but on a scale that makes them accessible. The River Greta is powerful and causes damage for sure, but it’s a miniature compared to the Snake River (US) or the Kawarau (NZ). Nonetheless, the Greta has impressive rapids as it passes through its gorge upstream of Keswick. Waterfalls get the artists’ attention but it’s river rapids where you feel the power of moving water.
