Haweswater reservoir is the highest lake in the Lake District. It started as a natural lake. Due to water demand increase, the reservoir system was built between 1935 and 1947. The dam was the first hollow buttress dam in the world. The development of the reservoir resulted in the submergence of Mardale village, the remains of which can still be seen when the reservoir levels are low.
The site offers spectacular views and is a great spot for keen birdwatchers, with sightings of Peregrines, Dippers and Redstarts. Deer are also present on the estate. Both level trails around the reservoir and more strenuous hill routes offer walking options for all levels.
The history of the site and wildlife spotting opportunities offer an impressive walk for all the family.
