This is, quite simply, the most wonderful setting for open water swimming. Calm, peaceful, exceptionally well maintained and with friendly and informative staff. I attended my first session today and will definitely return on a regular basis. I particularly love the fact that it has been sympathetically designed to embrace nature and is in a stunning location in the heart of Lincolnshire . The water was clean and surprisingly warm, the changing facilities excellent and the grounds exceptionally well cared for. I am new to open water swimming but felt extremely safe and it has given me so much confidence to continue . There is absolutely nothing to dislike if you want to swim at one with the natural environment.
