Firestone Bay (Devil’s Point)
Sea swimming, wildlife and heritage at the edge of Plymouth Sound
Where the River Tamar meets Plymouth Sound, Firestone Bay is one of the best known wild swimming spots in the city. At dawn you’ll find swimmers in the water. At low tide, families explore the rockpools. Throughout the year, seals are often seen offshore.
Above the bay stands the 16th century artillery tower, a reminder that this stretch of coastline has long watched over the harbour approaches.
What you’ll find
- A shingle beach and tidal pool within a designated bathing water site, popular for sea swimming, snorkelling, paddle sports and scuba diving
- A strong, welcoming open water swimming community
- Views across Plymouth Sound to Mount Edgcumbe and Drake’s Island
- Rich marine habitats including seagrass beds, anemones, crabs, lobster and a wide range of fish
- The Grade II listed artillery tower, now home to a restaurant.

Why it Matters
Firestone Bay and Devil’s Point show Plymouth Sound National Marine Park at its most active and inclusive. For many people, this is their first step into the sea. It is open, shared and part of everyday life in Britain’s Ocean City.
