Weymouth Bay Holiday Park is a Haven-operated caravan and lodge park in Preston, Weymouth, Dorset, situated close to a pebble-and-sand beach on Weymouth Bay. The River Jordan meets the sea nearby at Bowleaze Cove, just a short walk from the park.

It holds an AA 5 Gold Star Holiday Park award. The park features two swimming pools — one indoor, one outdoor — connected by a lazy river, along with a restaurant terrace, bar, and multiple food outlets.

An entertainment programme and a broad range of sporting activities round out the on-site offering. Accommodation is available in caravans and lodges.

The surrounding area provides easy access to notable Dorset landmarks including Portland Bill, Lulworth Cove, and Chesil Beach, while Weymouth town centre is a short drive away.
