RNLI Castle to Castle Swim 2024

The Castle 2 Castle Swim is an iconic one mile open water sea swim across the Carrick Roads. It starts at Pendennis Castle in Falmouth and finishes at St Mawes Castle on the Roseland Peninsula.

This popular event is strictly limited to 500 swimmers and is open to anyone over the age of 14. Please note, participants should be intermediate or experienced open water swimmers.

Registration for the swim is £30 and while we ask everyone to pledge to raise at least £70 through sponsorship, being the RNLI's 200th anniversary it would be amazing if you were able to raise £200, one pound for every year our volunteers have been saving lives.

The swim is an absolutely fantastic event largely run by volunteers, without whom it wouldn’t be possible. It promises to be great fun with a fantastic atmosphere, so do come along and get involved.

If swimming isn't your thing but you would still like to be involved, please get in touch as there are many volunteering opportunities available on the day.

Please read our Terms and Conditions, as well as the event specific terms and conditions below. You will need to agree to these as part of the sign up process.

• You must be at least 14 years of age on the day of the event to enter.
