Greywell is a Hampshire village reached via Junction 5 of the M3, then the A287 towards Odiham. Most visitors come from Reading, Guildford, or Winchester, whilst locals use the B3349 from Hook. The village sits in gentle chalk downland typical of North Hampshire. The Greywell Tunnel on the Basingstoke Canal serves as Britain's largest bat roost, sheltering over 1,000 bats through winter.
