Osea Island is an luxury island available for exclusive holidays, parties, events and as a unique wedding venue. Located surprisingly close to central London, Osea sits serenely on the Blackwater Estuary surrounded by four and a half miles of its own beaches and coastline. From the stately Manor House, to intimate cottages to courtyard apartments for larger groups. Most of our cottages are child friendly, some are pet friendly. All of our accommodation is self-catered. Osea is also available for private island hire.
