Sea Barn Farm is a licensed camping park set on a working cereals and beef farm near Fleet, Weymouth, in Dorset.

The site sits close to the Fleet Lagoon, an internationally protected nature reserve and wildfowl haven, with the Fleet shore and the South West Coast Path roughly 500 metres away.

Pitches accommodate tents, motorhomes, and a limited number of touring caravans. The park is geared toward campers who value scenery and a quieter atmosphere, and it draws a varied crowd including families, couples, cyclists, walkers, birdwatchers, and divers.

Its position on the Jurassic Coast also makes it a convenient base for exploring wider Dorset attractions, including Weymouth and Chesil Bank.
