New London Harbour boat ramp sits along the Southwest River on Prince Edward Island, near the point where Route 20 bridges the waterway.

The site offers convenient access to the Southwest River, a wide, tidal estuary located close to New London Bay and the renowned sandy beaches of the Cavendish area.

The river, though broad, is shallow and slow-moving, with stretches bordered by dense underwater grasses and sea lettuce.

Paddlers launching here can explore roughly 8 kilometres of tidal waterway that blends freshwater flow with ocean tidal influence — a characteristic common to most of PEI's river systems.
