Thrilling ocean adventures on St Mary’s

Get your heart racing with Kernow Coasteering’s thrilling coasteering adventure around Peninnis Head on St Mary’s, the only provider offering this experience on the Isles of Scilly. Set against dramatic granite cliffs and rugged sea‑eroded formations, you’ll scramble, swim and leap into the Atlantic in one of the UK’s most spectacular coastal locations.

This hands‑on adventure is perfect for those seeking excitement and natural beauty alike. Under expert guidance, you’ll explore tidal gullies, rocky outcrops and crystal‑clear waters, with opportunities for cliff jumps and wild swimming. No previous experience is necessary, though a basic level of swimming ability helps you make the most of the adventure.

All essential safety gear is provided and sessions are tailored to suit beginners and families. Ideal for ages nine and up (under 14s must be with an adult).
