Hanningfield Reservoir

Hanningfield Reservoir boasts mature woodland and offers superb views over the 870 acre Hanningfield Reservoir. The nature reserve offers some beautiful walks through the woodland, taking in bird hides, ponds and views across the reservoir. The site is run in partnership with Essex & Suffolk Water and you can walk through the reserve to the Essex & Suffolk Water Fishing Lodge and the Cafe on the Water. The reservoir itself is a Site of Special Scientific Interest (SSSI) due to the important numbers of wildfowl that use the reservoir in the autumn and winter, including Gadwall, Tufted Duck and Pochard.

Swimming in the beautiful waters, cycling on the quiet roads around the Reservoir and finishing with flat runs on trail paths through woodland.
