Cheltenham has more residential parks than any other town in Gloucestershire, with over 20 listed. Gloucester and Tewkesbury add more, and the Forest of Dean holds residential parks at Coleford, Cinderford, Lydney and Lydbrook.
Holiday parks split three ways: Tewkesbury, where the Severn meets the Avon; the Cotswold Water Park around Cirencester, Fairford and Lechlade; and the Forest of Dean.
Tewkesbury's riverside parks sit on a flood plain, and the town flooded in 2007. Ask any park near the rivers about its flood history and insurance, and ask every park for its season dates and fees.
