It’s easily the warmest lake in the region from October to March because of its depth, which retains the summer heat longer, compared to most local lakes which are much shallower, and lose their heat quickly.  e.g. as ambient temperatures hit their low-point, shallow lakes can dip under 2 degrees, while Dosthill Quarry is comfortably at 7 degrees. So the lake will be warmer than the region’s shallow lakes until around April each year.

If you already have a full wetsuit with arms & legs, consider wearing a shortie wetsuit over the top to keep the body core warm. You’ll get more water time, and get more cardio-respiratory benefit from the longer swim, with very little affect on the crawl stroke. Ian has been an ASA Swim Teacher for 52 years, so he knows the shortie technique really works.

Dosthill Quarry spring water is 500 times more pure than UK standards for tap water
So you’ll be missing out if you swim anywhere else!!

Not only have independent water tests confirmed the purity and clarity of the spring-fed lake, but also the presence of the spa mineral magnesium, considered to be the most important health mineral in the world. Read about the many health benefits here Magnesium – the most important mineral we all overlook.

No Swimmer’s Itch!

Unlike many shallow man-made lakes and former gravel pits that harbor freshwater snails, and parasites that infect swimmers, local residents and swimmers from many areas of the UK have enjoyed their sport free of the dreaded “swimmer’s itch” for more than 80 years. In fact, visiting swimmers who do have “the itch” often get better in this magnesium-rich, therapeutic spa lake.

Healthy Outdoor Training Centre

All abilities and ages are welcome, including costume-only and wetsuit swimmers (see our safety policy below). Whether you’re trying open water swimming for the first time, a child wanting to enjoy some splash time, or a member of our English Channel relay team you’ll get fitter and healthier at this amazing venue. Triathletes, in particular, can benefit from the variable rugged terrain of this 32 acre training centre by adding off-road bike and run phases to their swim session. Or anyone just looking to get fitter, or lose weight, can benefit from the healthy outdoor environment.

Our Own Swim-Bike-Run & Fitness Coach

ASA Swimming Teacher, Middle Distance Coach and former British team member, Ian Forster, is available for training tips and schedules.

Information on Outdoor Swimming

Safety Policy. Whether you wear a costume only or a wetsuit, you are welcome. But to protect you in the deep water, you need adequate buoyancy. Wearing a wetsuit is the preferred way to prevent you sinking in the event of cramp (and keep you warm), and to increase your confidence if you are new to open water swimming. Many of our strong & confident swimmers tow a swim float summer & winter alike! If you don’t have a wet suit or tow float you can hire one for £2 tow float, £6 shortie wetsuit, £8 full wetsuit, or buy your own on site at heavily discounted prices.

Course. If you prefer to swim around the 500 metre scenic route, swim anti-clockwise around the lake staying approximately 3 metres in from the granite cliffs. Alternatively, the above outdoor swimming course has been carefully planned to provide a single anti-clockwise 400 metre lap with 2 x 100 metre, and 4 x 50 metre legs for split times, and to help you practice the important open water skills of spotting & swimming in a straight line towards a buoy. 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 quarry walls, particularly at the southern end of the lap (bottom of photo) where occasional loose rockfalls 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 outdoor swimming 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. Should you see bubbles on the surface in front of you, during your swim be prepared to avoid the bubbles. However, by the time you get close to where you first saw the bubbles, normally the divers have moved well away.

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

Outdoor Swimming Declaration. The ASA require a declaration to be made on an individual’s ability to complete a planned outdoor swimming activity. “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. Our registration below includes this declaration.
