Derwentwater is tranquil & beautiful. You can take out a rowing boat on the lake or even a trip on one of the ferries for a circular tour of the lake or you can walk part or all of the way around. For the best views of the area then Catbells has to be one of the best walks in the Lake District with beautiful views of Derwent Water and the Borrowdale valley. For a more strenuous walk you can climb the mountains of Skiddaw, Helvellyn and Scafell – England’s highest moutain. If the weather turns bad, Keswick’s indoor attractions include The Puzzling Place, which is an exhibition based on optical illusion, where you can witness balls rolling up hill and more.
