I've been going here for open water swimming since the summer. Lovely venue. Very friendly staff and regulars. Easy to book online.

Brilliant place for open water swimming. Well managed and friendly atmosphere for any ability. Woke me up better than any coffee or yoga session this morning.

A great place. For large and small groups. I've taken my 9, 10 & 11 year old with friends over school holidays and a whole class of 30 for their leaving celebration. They've done paddle boarding, rafting, kayaking and more. The price is great for all day and I have no worries leaving them, the staff are friendly and knowledgeable. There are wet suits and changing facilities. A basic shower. There is also a cheap tuck shop which the kids love too. Highly recommended.
