  Our whole family absolutely loves it here. It’s a fantastic place, with amazing facilities and lovely staff. They do everything from classes and open sessions to kids’ holiday clubs; canoeing kayaking, paddle boarding, sailing, open water swimming, archery, climbing and more besides. For young and old, and all with lake loads joy!
