Swimming at Gildenburgh Water

Below is all the information you’ll need regarding swimming at Gildenburgh Water.


Opening Times. Swimming is available during daylight hours all year round during normal site opening times, provided you have adequate thermal and buoyancy protection i.e. a wetsuit to keep you warm and prevent you sinking. We recommend you check the Opening Times page to see if these standard times have been modified, particularly on bank holidays.

Monday to Thursday 9am-4:30pm. Last check-in at 3:00pm. Exit from the water by 4:00pm
Friday 9am-8pm. Last check-in at 6:30pm. Exit from the water by 7:30pm
Saturday & Sunday 8am-5:30pm. Last check-in at 4pm. Exit from the water by 5pm

Price. £5 per swimmer per session.

Course. The above course has been carefully planned and set out to provide a single 400 metre lap with 8 integral 50 metre legs for split times. Four laps (1600 metres) is 5 metres short of a mile. 1000 metres would be 2.5 laps. The course has been positioned away from the edge of the lake where branches from underwater trees, and reeds, can occur, and away from the diver training areas where diver ascents are more frequent. Other than when avoiding a diver, please ensure you stay close to the course buoys and on the course line.

Divers. Your swim may coincide with times when scuba divers are using the quarry. You can see where they are in relation to you by bubbles breaking the surface of the water. One of the safe practices all divers should follow when surfacing is to extend their arm, look up and around and surface slowly. We will advise them when swimmers are using the lake and remind them not to surface under or close to a swimmer.

However, should you see bubbles on the surface in front of you, during your swim please take evasive action immediately, by giving a wide berth to avoid any collision with surfacing divers.

Footwear. We recommend bringing suitable footwear, such as flip-flops, crocs, or some old trainers, for the transition in and out of the water to avoid any discomfort or injury to your feet.

Declaration. The ASA require a declaration to be made on an individual’s ability to complete an planned swim. “It should be quite clear to the swimmer that they are declaring that they are not only fit enough and have the stamina to complete the distance, but also that the swimmer is medically fit to do so”. Any pre-existing medical condition including medication and/or sensitivity to particular drugs should be included on the form.
