Discover the story behind Kernow Coasteering

Kernow Coasteering began in 2013 with a handful of wetsuits and a mission: to share the wild joy of exploring Cornwall’s coastline. What started in West Cornwall soon expanded to include guided climbing routes and coasteering trips on the Isles of Scilly. Since then, we’ve guided thousands of people through some of the most exciting coastal terrain in the UK.

The Person Behind the Adventure

Kernow Coasteering is run by Matt George, who founded the company in 2013. A lifelong adventurer and experienced coasteering guide and climbing instructor, Matt has a deep knowledge of Cornwall’s cliffs, sea caves, and hidden gems. He’s guided thousands along this coastline with a careful, grounded approach. Matt also has an ongoing project to coasteer every inch of Cornwall’s coastline. So when we say that no one has explored more of Cornwall’s coastline than us — we mean it!

He’s joined by a small, trusted team of freelance coasteering guides and rock climbing instructors who share his approach: professional, grounded, and focused on the experience.

Project Cornwall: Coasteering Every Inch of the Cornish Coast

Exploring the Coastline, One Wild Section at a Time

A long-term mission to coasteer the entire Cornish coastline. From sea caves and zawns to remote cliffs and hidden beaches, this is coastal exploration in its rawest form.

Each section is tackled on its own terms — no shortcuts, no skipping the awkward bits. Over time, a detailed picture of Cornwall’s coastline is emerging, built from first-hand experience in the water.

Why it Matters

There’s a tragically underexplored world waiting to be discovered. You don’t need to go to the Himalayas or Antarctica to find adventure — new ground is waiting all around the coast. Most people just don’t look.

Cornwall’s Coastline: How Far We’ve Come

Our journey around Cornwall is logged section by section — each new stretch adding to a growing picture of the whole. From Land’s End to the River Tamar, every mile tells a different story.

Cornish Sea Caves & Arches

Every cave and arch here was logged through hands-on exploration of Cornwall’s coastline — from narrow squeezes to colossal coastal labyrinths. In many of these caves, it’s likely no human had ever reached the back before.
