Scuba Diving in Cornwall

Clear days, kelp forests swaying like underwater gardens and a coastline peppered with stories—scuba diving in Cornwall offers shore and boat dives for every level. The centres above run try dives, full PADI/BSAC courses, guided explorations and air/nitrox fills, with hire kit if you’re travelling light.

What you can book

• Discover Scuba/try dives in pools or sheltered coves

• Open Water/entry‑level courses and continued training (Advanced, Rescue)

• Guided shore dives on reefs and gullies rich with life

• Boat dives to reefs and (conditions permitting) wreck sites

• Kit hire & servicing, cylinders, weights and fills

Safety & planning

Choose reputable centres with qualified instructors, safety briefings and conservative dive plans matched to experience and conditions. Share medical history and ensure you’re within no‑fly guidance if you’re flying soon. Water is cooler than you think—ask about appropriate exposure protection (many divers use semi‑dry or drysuits outside high summer).

Cornwall‑wise tips

• Tides, swell and vis vary—trust your guide’s call on the day.

• Bring a warm hat and layers for surface intervals; even sunny days can chill after a dive.

• Respect marine life: look, don’t touch, and maintain buoyancy control around kelp and reef.

• Non‑divers in the group? Many sites pair well with coastal walks and cafés while you’re underwater.
