The best spots for swimming outdoors in the South West

Outdoor and open water swimming is experiencing a surge in popularity, with more and more of us searching for spots to cool off on a warm summer’s day, and the hardier among us continuing to swim all year round. Many people swear by the health benefits of open water swimming, including a boosted immune system, increased happiness and better sleep. Sound good? Why not try it yourself?

The South West of England is blessed with a long coastline, which means there’s no shortage of beaches for you to take the plunge from, but our region is also home to many lakes, rivers and open-air swimming pools that are perfect for an al fresco dip.

Pull on your swimmers and grab your towel and goggles as we dive into some of the best spots for outdoor swimming in the South West. We’ve broken down our suggestions so you can go as wild as you want to, from a gentle freshwater splash in a purpose-built pool right through to totally rugged rivers and natural pools.

The beauty of these spots is that they’re all relatively remote, so you’ll often need to take a taxi from the station or, alternatively, take your bike on the train with you and cycle to your chosen swimming spot.

Lidos and outdoor swimming pools in London and the South West

All up for an al-fresco soak but not quite ready to take to wilder waters? Then why not dip your toes into this activity by heading to an open-air swimming pool. With options that include heated pools and those with lifeguards on duty, this is a more family friendly way to swim outdoors.

Chagford Swimming Pool, near Newton Abbot

This charming location features a heated, open-air pool that’s fed by the River Teign – the largest freshwater swimming pool in the South West of England.

Set on the edge of pleasant Brockwell Park, this open- air pool in London is a sight to behold. Surrounded on all sides by Grade II-listed art deco architecture and lush greenery beyond it, the brisk waters certainly look tempting, no matter the weather. You can visit Brockwell Lido and take a dip or get yourself booked in for an activity such as an aqua dance or Pilates class. Either way, you’ll find it easy to reach from London Waterloo – just use southbound Northern and Victoria Line services to get to Brixton. The Lido is just 16 minutes’ walk from there.

Lymington Sea Water Swimming Baths, Lymington

Right on the harbour where the Lymington River meets The Solent, this sea water baths has been entertaining guests since 1833. Back then, this spot was renowned for its health-giving waters and natural mud minerals, but it’s high-octane family fun that’s the main draw for crowds today. Guests can attempt to tackle more than 200 metres of wacky inflatable assault courses, alongside other activities like aqua jousting, stand-up paddle boards and hot tubs to hang around in. If that sounds up your street, get yourself to Lymington Town station. The baths are just 14 minutes’ walk along the waterfront from there.

The Serpentine, London

You may not have thought that London would have much to offer when it comes to outdoor swimming spots, but as well as several lidos dotted around, there are also a few lakes that are a haven on sticky summer days in the city. The Serpentine, in Hyde Park, was created in 1730 and was one of the first manmade lakes in England that was designed to look natural. Nowadays, it’s a peaceful place to escape the hustle and bustle of London and cool off – you'll need to join The Serpentine Swimming Club first though! Take the train to London Waterloo then jump on the Jubilee Line to Green Park and walk from there.

Eastleigh Lakeside, Eastleigh

Located in the picturesque Lakeside Country Park in the New Forest, Eastleigh Lakeside is a large lake that’s perfect for open-air swimming. It’s shallow enough to stand the whole way around – so it’s a good spot for beginners as well as avid swimmers – and you can swim small sections of it or try the whole 350m loop. Register online before your first swim, then dive right in and admire the idyllic surroundings. Catch a train to Southampton Airport Parkway, and you’ll find the lake less than 15 minutes’ walk away.

Salmon Leaps, near Castle Drogo

Rapids are a recurring theme in Dartmoor, and Salmon Leaps is the ideal spot for wild swimming with a twist. Set below the National Trust’s Castle Drogo, Salmon Leaps is part of the River Teign and is made up of three plunge pools with connecting “slides”. The water is shallow (and approximately 1.5 metres at its deepest point), and adults and children alike will enjoy moving with the current between pools. Be cautious at the bottom pool, as the current can be strong and there’s a hidden underwater rock, so if you’re there with kids, make sure an adult is there to catch them at the bottom. Visit in autumn for the chance to see salmon leaping over the dam! The nearest station is Exeter St. David’s. From there, it’s a 30-minute taxi ride to Castle Drogo, and then a scenic woodland walk will lead you to Salmon Leaps.

Colber Bridge, Sturminster Newton

Glide into the serene and still waters beneath Colber Bridge on the River Stour and let all your troubles float away.
