London and the South East’s Prettiest Diving Site
Mercers lake offers great diving in a beautiful location. The lake is surrounded by a country park with green forests that dog walkers and families are free to enjoy. Our partners at Aqua Sports have given us EXCLUSIVITY ON DIVING to the lake, so you won’t find lots of other dive schools here fighting for platforms or stirring up the bottom.
The lake was formerly a sand quarry but has now been turned in to a fantastic watersports and diving centre. This conservation area is home to lots of wildlife in and out of the water.
Divers benefit from clear waters, with visibility normally in excess of 8m. The lake is surrounded by an underwater forest which is home to tonnes of fish including perch, pike, bream and giant carp. We are still discovering new and exciting parts of the lake but our explorations have found an average depth of around 8m with a maximum depth of 15m.
What is there to see?
This area of outstanding natural beauty continues under the waterline. The clear waters (average of 5-8m viz) are home to a variety of small and large fish including perch, pike, carp and large schools of juvenile fish.
The water level was increased by around 4m a few years ago so the old shoreline is clearly visible. You can bimble through underwater woodland and see the old infrastructure.
There are a few wrecks of old sail boats to swim around as well as the remains of an old plane.
For customers enrolled on courses we have platforms to make completion of skills more comfortable.
- The Cafe is inside the centre has a sunny terrace and dry lounge, offering the finest Barista-style coffee, teas of many descriptions, snacks and cold drinks, hot chocolate for the less sunny days, plus toasties in season.
- Toilets including disabled facilities
- Changing room and hot showers
- Rinse tanks
- We have our own pontoon
- On the Sunday we typically visit a local country pub for some refreshments and complete the paperwork
As the lake is very large we have two main dive sites:
Named after the ‘Hanging Gardens of Babylon’, one of the seven wonders of the World, this is our main training site located in front of the pontoon. Once you pass the training platforms and the sunken boats you will arrive along the old shore line. The old woodland is draped in natural curtains resembling an ancient natural garden. This is home to large numbers of fish life. Maximum depth tends to be around 8m.
Named in homage to the worlds best dive site. Like it’s name sake this is where the largest fish in the lake tend to hang out and hunt on the large schools of smaller fish. Among tree branches and under sunken fencing you frequently see sleeping pike in excess of 2 feet, huge carp lazing around and schools of smaller fish keeping an eye out. This roped off area has a maximum depth of 12m.
