Heron Lake Swimming 2014

Heron Lake is one of the largest Open Water Swimming venues in England

Located just 100 metres off the M25 junction 13, not only does it have beautiful surroundings, safe and clean water but there is also a clubhouse with showers, changing facilities, food and hot drinks available. There is ample parking available for over 150 cars, and we regularly get 600+ swimmers a week.

Heron lake is one of the premier open water swimming locations to swim in Berkshire and Thames Valley, where Safety is our priority.

Open Water Swimming and Triathlon

As the popularity of both open water swimming and triathlons continues to grow, Heron Lake is a perfect facility to test out your new wetsuit, get coaching to improve your open water swimming or just train for your next event.

Whether you are a first time swimmer or a seasoned professional, Heron Lake Open Water Swimming encourages everyone to come down and use the lake.

Significant payments are made to the British Disabled Water Skiing Assocation (BDWSA) who have their head quarters at Heron Lake. This money helps provide support to disabled athletes and those rehabilitating from injury.

Heron Lake is the Premier Open Water Swim Venue in the south of England and is a not for profit organisation.

It is a great place to train with other swimmers and meet other like minded athletes aiming for a common goal.
