Open Water Swimming is closed.
We will re-open Wednesday 7 May 2025.
Enjoy a refreshing open water swim around our 400-meter course 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 2024 season all open water swimming sessions are Wednesday evenings only from 6:30pm - 8pm. The season will start on Wednesday 8 May and finish on Wednesday 4 September. Please note that the water temperature must be at least 11.5°C for us to run these sessions.
If you are new to open water swimming and have swum less than four times in open water you must inform the beach master of this before you enter the water. A tow float must also be used.
If the water temperature is under 16°C wearing a wetsuit is compulsory. Everyone's reaction to the cold water is different and if you have not done open water swimming before you will find it very cold. Should you wish to wear one, a well-fitting wetsuit will offer you warmth and buoyancy. 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 Evesham
- 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: You still take part in the rain. Our theory is that you are going to get wet anyway! It is good fun in the rain.
Lightening: If we have lightening overhead, then we will pause and resume once the storm has passed. Then your time will continue as normal. This does mean we may have to delay later sessions if this does occur.
