Water Safety

We just want to reassure you that you are in very safe hands while taking part in your swim. We have lots of fully trained water safety kayakers, lifeguards and boats monitoring you all the way around, so you're never far from some friendly support.

If you find yourself struggling, or in need of a little breather, just lay on your back and pop your hand up, and one of our safety team will make their way to you to check everything is ok.


If you're looking for somewhere to stay for your Great East Swim why not get the tent out and make it a real family adventure. The Alton Water Camping and Caravanning site opens Friday 1 June and is ideally situated for the Great East Swim so you can just roll out of bed, into your wetsuit and into the water. Plus with its newly refurbished Tea Room serving hot food throughout the day and brand new shower and washing facilities it'll be like a home away from home.
