Home of Milton Keynes BSAC club (MKSAC) the Blue Lagoon at Bletchley or ‘Bluey’ is available to dive by prior arrangement with MKSAC.

The lake is spring fed and can have a large temperature gradient, we have experienced 8°C at depth while the surface is 19°C so come prepared.

The max depth is 18m and there are a number of underwater attractions, cars, boats etc. as well as a large population of crayfish.

The lake is in an area of parkland used by locals so can be busy with dog walkers in good weather.

There are no facilities of any sort so bear this in mind when planning your visit!
