Osea Leisure Park is a five-star holiday park set on the banks of the Blackwater Estuary near Maldon, Essex.

Its history stretches back to the 1930s, when pea-pickers camped in the fields here; today it has grown into one of Essex's most highly regarded leisure parks, holding both a VisitEngland 5 Star Holiday Park rating and a David Bellamy Conservation Award Gold.

Accommodation ranges from touring and camping pitches — electric and standard — to lodge tents, pods, shepherd's huts, treehouses, and glasshouse-style glamping units.

On-site dining is available at The Deckhouse and the Osea View Café, and the park hosts seasonal events and live entertainment.

Its position alongside the estuary gives walkers and cyclists ready access to coastal and inland routes throughout the surrounding Essex countryside.
