Willsbridge is a village in the unitary authority of South Gloucestershire, England, located on the outskirts of Bristol. Willsbridge Castle, situated on a prominent hillside site, was built around 1730, with crenellations added in the nineteenth century.
The village contains a nature reserve, Willsbridge Mill, run by the Avon Wildlife Trust and the site of an abandoned watermill on the Siston Brook, which acts as an Education and Countryside Centre. Willsbridge Mill and Valley are leased from South Gloucestershire Council.
The valley contains many habitats. The woodlands have carpets of Common Bluebells, champions and resound with birdsong.
