Chilterns Countryside, Buckinghamshire
This circular, 6.1 miles (9.8 km) walk starts at the site of an extensive Roman villa complex with a dark history. It then crosses the River Thames via a weir and a lock at Hambleden Mill, before heading upstream along the river bank alongside the regatta course to Henley-on-Thames. This stretch of river is usually busy with boats of many types, and a wide variety of geese, ducks, swans, cormorants and other water birds. In the summer months it is popular with numerous leisure boats.
