There is no swimming pool in Burnham, though there is a group of volunteers, called BOLD, trying to change that.
The nearest pool is a 15m swimming pool in Southminster that is open for public use. For contacts and more, click here or take a look here.
Otherwise, the nearest pools are at the Blackwater Leisure Centre in Maldon, or the South Woodham Ferrers Leisure Centre.
