Cod Beck reservoir is a man-made lake covering a surface area of around 10 hectares. Lying within the North York Moors National Park in North Yorkshire, it is surrounded by woodland.
Camping, fishing and swimming are prohibited for public safety and to protect the environment; however, the location is good for walkers. There is a 45-minute circular path around the reservoir (covering just under 3.2 km / 2 mi). The Cleveland Way, a National Trail, passes within half a mile of the lake and other paths lead up onto the high moors. There are several car parks at the head of the reservoir, but these get very busy in peak season.
