West Sussex mixes coastal holiday parks with residential parks inland, so the choice here turns on whether you want a holiday base or a permanent home. This page brings both together.
The coast runs from West Wittering and Selsey through Bracklesham Bay, Bognor Regis and Littlehampton to Lancing and Worthing. Inland, Arundel, Storrington, Horsham and Steyning hold residential parks within reach of the South Downs.
Chichester and Arundel put the area within two hours of London by train, which keeps demand high and stock moving. Most residential parks here operate over-45s or over-50s rules, so check the age restriction and the pitch fee before you enquire.
