Chesham Moor Gym and Swim

A proper leisure facility rather than a tourist attraction, Chesham Moor Gym and Swim serves the local community near Amersham with the kind of no-nonsense approach you'd expect from a British sports centre. There's a swimming pool, gym equipment, and fitness classes - the sort of place you'd actually use if you lived round here rather than visit as a holiday highlight.

If you're staying at one of the nearby campsites like Fuzzy's Farm or Penn Meadow Farm with restless teenagers in tow, it's worth knowing about. A wet afternoon when the weather's turned can be solved with an hour in the pool, and the gym facilities mean adults can get a proper workout without driving miles. The staff are straightforward and the place runs efficiently, even if it's not going to set anyone's heart racing.

You'll need to check their website for current opening hours and membership or day pass rates - these change seasonally and depend on whether you're a local or a visitor. Allow a couple of hours if you're bringing the family, less if you're just popping in for a swim. It's functional rather than fancy, which is exactly what you want when you've got a few days' holiday to manage and the kids need burning out.

Not a reason to choose a holiday in Buckinghamshire on its own, but a practical backup option if you're already based at one of the surrounding campsites and need somewhere indoors.
