There’s something undeniably special about arriving on the Isles of Scilly. The light feels softer, the pace slower, and the sea impossibly clear. But beyond the white-sand beaches and calm island charm lies a wilder side—one best discovered not from the shore, but right at the rugged edge of it. Welcome to coasteering on Scilly.
What is Coasteering?
Coasteering is an exhilarating way to explore a coastline by scrambling over rocks, swimming through sea caves, and leaping into deep, turquoise pools. It’s part adventure, part exploration—and on Scilly, it takes on a whole new level of magic thanks to the islands’ pristine waters and dramatic granite formations.
The Perfect Playground
The Isles of Scilly offer an ideal natural playground for coasteering. Around St Mary’s and St Martin’s, you’ll find hidden coves, natural arches, and sheltered inlets that are perfect for both beginners and more experienced adventurers. The clarity of the water is astonishing—you can often see straight to the seabed as you swim.
Expect to navigate barnacle-covered rocks, discover secret caves, and climb up to natural jump spots where you can plunge into the Atlantic below. Each route is different depending on tides and conditions, making every trip unique.
Guided Adventures : Kernow Coasteering
For safety and local knowledge, coasteering trips are typically led by expert guides. Kernow Coasteering is one of the main providers, offering sessions tailored to all abilities. Their experienced instructors know the coastline intimately—meaning they’ll take you to the best spots on the day, whether that’s a calm, sunlit cove or a more adrenaline-fuelled stretch of exposed rock.
Discover the wild side of Scilly as you swim, scramble and jump your way along this beautiful granite landscape. Weave your way through amazing rock formations, narrow gullies, and under giant boulders. And of course, a wide array of cliff jumps awaits you, from simple step-offs to huge precipices – but don’t worry, all jumps are optional.
Kernow Coasteering will provide you with a winter wetsuit, helmet and buoyancy aid. All you need to bring is a pair of lace-up shoes to wear in the sea and an extra pair of shorts to go over the wetsuit. The minimum age is 9 and all levels of experience are welcome. Advance booking required here.
Wildlife Encounters
One of the unexpected highlights of coasteering on Scilly is the wildlife. As you swim between rocks, you might spot curious seals bobbing nearby, or catch glimpses of starfish and crabs beneath the surface. The islands are part of a designated Area of Outstanding Natural Beauty, and the marine life here is thriving.
A Different Perspective
Coasteering gives you a completely different view of the Isles of Scilly. You’ll see parts of the islands that most visitors never reach—hidden corners only accessible from the sea. It’s a chance to connect with the landscape in a raw, physical way, feeling the swell of the ocean and the texture of the rock beneath your hands.
Tips for Your Trip
- Book ahead in peak season – summer slots fill quickly
- Bring swimwear and trainers – you’ll need sturdy footwear for grip
- Trust your guide – jumps are always optional, and safety comes first
- Embrace the adventure – it’s as much about fun as it is about challenge
Make It Part of Your Stay
Whether you’re visiting for a weekend or a longer island escape, coasteering is a fantastic addition to your Scilly itinerary. Pair it with slower days spent beachcombing, island hopping, or enjoying fresh seafood by the harbour.
In a place known for tranquillity, coasteering offers a thrilling contrast—an opportunity to experience the Isles of Scilly at their most untamed. And as you float in the clear Atlantic, surrounded by ancient rocks and endless sky, you’ll realise there’s no better way to feel truly immersed in this remarkable corner of the world.
