Bristol has a small number of residential parks on the fringes of the city. This page lists those with park homes for sale.
Look at Whitchurch and Downend inside the city boundary, Keynsham to the south east, and Hallen, Portbury, Flax Bourton and Lulsgate towards the M5 and the airport. These are permanent residential sites rather than holiday parks.
Age restrictions apply on nearly all of them and pitch fees are charged monthly. If the choice here looks thin, the parks in Somerset, Gloucestershire and Wiltshire sit within half an hour and carry more stock.
