Open Water Swimming will re-open Wednesday 7 May
Enjoy a refreshing open water swim at Aztec Adventure Upton Warren. The lake is stream-fed and the water is regularly tested for water quality. All our sessions are supervised with lifeguards both on and off the water.
All swim courses are to be swam in a 'clockwise' direction around the lake. Changing rooms and showers are available.
For our 2025 season all open water swimming sessions are Wednesday and Friday evenings only from 6pm - 7:30pm. The season will start on Wednesday 7 May and finish on Friday 12 September. Please note that the water temperature must be at least 11.5°C for us to run these sessions.
All swimmers must wear a brightly coloured swimming hat, and we strongly recommend that tow floats be worn by all swimmers.
If you wish to wear a wetsuit, a well-fitting one will provide both warmth and buoyancy.
If the water temperature is under 16°C wearing a wetsuit is compulsory. However, everyone's tolerance to cold water varies, and if the water temperature is above 16°C, you may still find it colder than expected, especially if you are new to open water swimming.
Please see our facebook page for updates on the water temperature.
We are thrilled to be offering Adults' Open Water Swimming Courses if you are new to open water swimming or if you would like to improve.

Pets and assistance dogs
Currently, we do not allow dogs at:

- Aztec Adventure Upton Warren
Aztec Adventure Upton Warren is very fortunate that its home is on a Site of Special Scientific Interest (SSSI). We have a duty to protect our flora and fauna; a condition of this is that Natural England do not allow dogs on site.
Aztec Adventure The Lost Valley welcomes well behaved dogs and their owners! The Valley is dog friendly with walks, dog events and benefits from having some dog-friendly stores.
Dogs are allowed at Aztec Adventure Lower Moor but must be on a lead at all times. Please note that dogs are not allowed in the lake.
Please note no other animals are permitted at Aztec Adventure The Lost Valley and Aztec Adventure Lower Moor.
All of our sites do allow assistance dogs.
Wildlife and fish
There are ducks and geese that live on and around the lakes at Upton Warren and Lower Moor. There are also fish in the lakes, both large and small.
What happens with bad weather?
Rain: Our sessions will still go ahead if it’s raining—after all, you’re going to get wet anyway!
Lightening: If we observe lightning and hear thunder in the vicinity, we must pause the session for safety reasons. Ensure all participants are on the shore. We unfortunately will not be able to restart the session for at least 30 minutes. If conditions improve and we can safely resume without affecting other sessions, we will do so. If not, you have the following options:
- Rebook onto a session later in the day, subject to availability.
- Rebook for a different day.
- Request a refund.
Your safety is our priority, and we appreciate your understanding.
