Ullswater is the second-largest lake in the English Lake District. There are two villages on its shoreline: Glenridding, on the southern end, and Pooley Bridge, on the northern end. Considered to be the most beautiful of the English lakes, Ullswater is often compared to the superb Lake Lucerne in Switzerland. The greatest attractions of Ullswater are the lake steamers which offer tourist trips around the lake. Another of Ullswater`s attractions is the spectacular waterfall of Aira Force on the lake`s western side.
