Dive-site story
Located on the northeastern coast of Jersey, St Catherine's Breakwater offers one of the island's most reliable and accessible shore dives. Divers enter from the slipway or step off along the sheltered side of the Victorian granite breakwater, navigating across a mix of kelp-covered boulder slope and sand flats. The structure serves as an artificial reef that concentrates temperate marine life and provides dependable shelter from prevailing westerly winds.
Extensive granite breakwater blocks providing refuge for encrusting organisms and hiding fish
Sheltered conditions shielded from western Atlantic swells
Kelp forests transitioning into sand beds frequented by rays and flatfish
