The original, iconic 15km staged swim challenge between the islands.

6 swims, 6 walks - complete over 1 or 2 days.

Outstandingly beautiful, remote and unspoilt, the Isles of Scilly are every open water swimmer's dream.

Event date/s: Two Day event: Thurs 17th & Fri 18th September, One Day event Sunday 20th September 2026

Just off the coast of Cornwall, this special place boasts ice-white beaches, Caribbean-like blue waters and picture-perfect harbours and bays.

Now in its 13th year, the Scilly Swim Challenge showcases some of the very best swimming the UK has to offer, offering participants the chance to swim and walk between the islands, safe in the knowledge they will be looked after by a team of open water experts.

The combination of swimming in the cold sea with the backdrop of the beautiful islands & changing (often challenging) conditions is an incredible experience.

But this isn’t just about ticking off a bucket list.

It’s about raising money for Level Water – a charity giving children with disabilities the chance to learn to swim. These 1-to-1 lessons build confidence and joy in the water and wouldn’t exist without your support.

Every £15 funds a lesson.

Together, we’re opening up the water to everyone.

This is one of the greats – and it fills up fast.
