Walking with his sister on a stormy day, Wordsworth was inspired by field of daffodils beside Ullswater to write his most famous poem. The lake is one of the most accessible in the Lake District, just inside the National Park from the M6 Penrith junction. The A592 skirts the west side of the lake opening up stunning views of mountains and meadows. There are low level, lakeside walks including the National Trust trail to the Aira Force waterfall, as well as the start of several hikes into the higher fells.
