Over a hundred years ago two small lakes and a small hamlet were drowned by the building of a large dam at the northern end of the valley.

The reservoir supplies water to Manchester with a low level circular route to walk around.

Being a circular walk you can start at any of the car parks, Swirls is a popular one with it being a starting point for Helvellyn so we always find the opposite side is much quieter, 

There is no swimming in Thirlmere reservoir, options to go to the water and throw stones.

Thirlmere also has a variety of smaller walks in the forest, you can walk up to Harrop Tarn, or if your feeling more energetic to Raven Crag which has amazing views across the water.

There is sections that are also suitable for cyclists so be careful if walking on the road.
