See Booking for when sessions are running.
Swineham is only authorised for swimming during operational hours, and any swimming outside of these hours will be trespassing on private property and risk prosecution.
There is a public footpath which goes close to the lake area should you wish to see where the lake is, prior to a session, however no admittance is permitted beyond the gate and fenced area outside of the session times. If you wish to walk up towards the lake, you will need to leave your vehicle in Bestwall Road, Wareham, as there is no vehicular access beyond the Rugby Club entrance outside of session times. This rule is strictly enforced and you will risk being banned from actual sessions should you be found to be ignoring restrictions.
