Situated in rural surroundings, Southdown Marina is very family friendly and just a short dinghy ride away is the City of Plymouth.

This marina is on the Cornish side of the River Tamar. Having passed Drake's Island in Plymouth Sound and entered the Hamoaze with Cremyll Point to port, you will find Southdown Yacht Club situated on the north side of Millbrook Lake, behind lovely Mount Edgecumbe Park. The location is sheltered and well placed for exploring. The marina lies within the jurisdiction of the Queen's Harbourmaster. It is quiet, non-commercialised and friendly to visiting yachtsmen and their families. Berths are walk-on pontoons or quayside and helpful personnel can assist you with enquiries about facilities and services.
