Lake Swimming

With its sheltered, peaceful location and clean, fresh water, Trevassack Lake is lovely for open water swimming, all year round.

Whether you’re a recent chlorine convert or have plenty of experience in Cornwall’s wild waterways, we’d love to welcome you to Trevassack Lake. Whilst in the water, marked areas will guide you to swim where suitable for your session, be it a quick dip or triathlon training around the lake’s edge. 

We have changing rooms, warm showers and toilets available for use, included in your price. The waterside cafe is perfect for warming up with a coffee and cake after your swim!

By swimming at Trevassack Lake, you’ll not only spend time immersed in nature, reaping the benefits that wild swimming can bring to your mental and physical health, you’ll also be supporting the work of Children’s Sailing Trust to create affordable and accessible watersports in Cornwall.
