Downderry is a south-facing, sand and pebble beach with rock pools at low tide. It is located 4 miles from the western-most end of Whitsand Bay in the far south east of Cornwall, 18 miles from Plymouth. At low tide, the cliff-backed beach stretches to around a mile and reaches Seaton.
A small car park is located in the village of Downderry, from which the western end of the beach is easily accessed via a path or slipway. There is disabled access to the western beach. Access to the eastern end of the beach is difficult.
Refreshments can be taken in a beachside pub or in the cafés and restaurants of the village. Public toilets are situated at the car park. Downderry Beach is dog-friendly. There is no lifeguard service, though the beach is equipped with rescue equipment.
