Where to Swim Outdoors in London

Brockwell Lido

Swimming outdoors might be something you only associate with foreign holidays but hurrah, it is possible to swim in the outdoors in London. A multitude of lidos and ponds give city dwellers the chance to dive in a cool off. Many lidos offer kids the chance to splash and play or take swimming lessons. Here are some of the best to choose from when you feel the need to cool off, float or get some aquacise.

Before setting out to any of these swimming locations be sure to check opening details on their websites or social media accounts. Some require pre-booking and some have limited hours.

Hampton Pool

Swim outdoors in heated water all year round! Hampton Pool, known as “South West London’s best kept secret” is situated next to Royal Bushy Park. The main pool is 36 metres long and there is a learner pool dedicated to children and their parents. There is also a pool-side gym and fitness classes, outdoor concerts and events. Kids can partake in lessons and activity camps.

Hillingdon Outdoor Pool

There is a paddling pool and play area for kids, as well as sun loungers.

Hampstead Heath Swimming Options

Choose from four options in gorgeous Hampstead Heath: Parliament Lido, the men’s pond, the women’s pond or the mixed pond. The lido is a big unheated outdoor pool popular with families and the ponds are adult havens, set in lush natural settings with birds bobbing along with you.

Finchley Lido Leisure Centre

Finchley Lido Leisure Centre is located in Great North Leisure Park in Barnet. It is a great place for family swimming with a leisure pool that includes a wave machine, jets and other fun features. The 25m pool offers a comprehensive ‘Learn to swim’ programme and during the summer the outdoor pool is a great place to swim and have fun.

Brockwell Lido

And one last thing…

Outdoor or “wild” swimming might not be your thing but perhaps you’re feeling a little bit adventurous. If so, the Wild Swimming site lists potential spots all over the country (although, to be honest, I don’t know if I’d be brave enough to swim in the Thames). And one last special mention for that famous west London landmark, the rather confusingly named Ruislip Lido. Of course, it’s not a lido in the sense of the outdoor swimming pools mentioned above, but a 60-acre lake with its very own sandy beach on the edge of Ruislip Woods. At present, swimming is not permitted but there is a playground, a water splash pad, and this is still a natural beauty spot that would be perfect for a picnic.


If you’re planning on visiting any of the above pools, we highly recommend you check the sites first, not only for opening times and price information but also to make sure you’re not going to gate-crash any pre-booked activities or classes. And if it’s a hot day, there’s a very good chance you won’t be the only person taking their family for a dip in the pool—aim to leave early or be prepared to join the queue!
