Hampton Pool is open 365 days a year (yes you can even take a dip on Christmas Day!) and it’s heated! Sitting next to Royal Bushy Park, this 36m long pool has plenty of space for everyone and being hidden away in South West London you might even get a proper swim on a summers weekend.
Stoke Newington West Reservoir is not really the kinda place you’d take a dip in your bikini, but it is the kinda place you can dive on in with a wetsuit to go open water swimming. This is one for those hardy swimmers out there.
Kings Oak Lido is nestled in Epping Forest, and is more than a little bit swish. The 1930s lido is part of the Kings Oak Hotel and comes with fountains, champagne beds, tiki bar and waitress service.
Pools On The Park is on the Old Deer Park to be precise. Built in the 1960s, this outdoor heated pool is only open in the summer and has lots of space for sunbathing.
Unless you’re a hardcore swimmer you probably didn’t know you could take a dip in the Royal Docks. This is proper open water swimming and temperatures tend to stick around 18°, but who doesn’t want to take a dip in one of the most iconic spots in London?!
If you fancy swimming amongst the swans and ducks, jump on into Serpentine Lido. Open to the public throughout the summer, this unheated lido is perfect for a hot summer day and even has a private sunbathing area.
Measuring 50m x 23m, Park Road is one of the largest lidos in London. It dates back to 1929 and comes with diving boards, a cafe and grassy slopes that you could easily spend all-day sunbathing on.
If you’re not down with swimming with the wildlife at Hampstead Heath, dive on into Parliament Hill Lido. Even though this pool is unheated, it’s surrounded by a beaut Art Deco building and has a swanky stainless steel liner that gives the water a real shimmer.
After a £2million re-furb is 2013, Charlton Lido is one of the swishier outdoor pools in town. The 50m pool comes with two sun terraces and a cafe, and is the perfect place to spend a sunny afternoon.
Hillingdon Lido was restored back to its glory days in 2010 and even comes with fountains. Looking just like it did in the 30s, this Grade-II listed, 50m lido is West London’s hidden gem and perfect for a bit of backstroke.
As the name suggests this is a little OASIS in the centre of London. Measuring 27.5m, this heated pool is the perfect place to cool off in the summer and even has a little sun terrace to top up your tan.
West Finchley Finchley Central
Finchley lido might not be the biggest pool at only 25m, but it’s the perfect spot to cool down on a hot summer’s day. And if you’re not down with swimming you can always catch some rays and enjoy an ice cream on a sun lounger.
If you really want to get back to nature go for a dip in Hampstead Heath Ponds – you’ll be taking a swim with the wildlife. Open all-year round and unheated (it is a pond!), this one is only for the brave.
Measuring at 91.5m Tooting Bec Lido is the largest outdoor fresh-water pool in the UK and has been around since 1906. Famed for its iconic Pantone-coloured changing huts, this one is as pretty as a picture and pretty bloody cold unless you go in the height of summer.
