The 10 most beautiful wild swimming spots in the UK

Looking like something straight out of a Gainsborough landscape, Port Meadow is a stretch of common land roamed by cows and horses that sprawls out from the upper reaches of the Thames (known in these parts as the Isis). It’s no wonder it’s such a popular spot for a dip on hot days. Aim to dive in down by Fiddler’s Island, the bit nearest central Oxford, or upriver at Godstow and Wolvercote, where you’ll find the remains of a former official bathing place.

You’ll be hard-pressed to find a more striking backdrop for a wild swim than this fairytale plunge pool with an 18-metre waterfall crashing down into it. Surrounded by a wooded glade in the middle of Northumberland National Park, the foaming pool is just big enough for a small group to wade in on a hot day. 

Set in the shadow of snow-capped mountain Ben Lui, this alfresco swimming spot is framed by a dramatic ten-metre waterfall and delicate woodland canopies. Just off the West Highland Way – and accessed via a bumpy farm track – the large circular plunge pool is known locally as Rob Roy’s Bathtub (a fabled Scottish outlaw who may or may not have bathed here). It makes for a tranquil spot to spend an hour or two lolling around in the cool water.

Margate’s elusive tidal pool is impossible to spot at high tide, as it is only when the sea draws away from the shore that its concrete walls are visible over the lapping waves. During winter, this enclosed four-acre section of Walpole Bay attracts mostly pretty hardcore pro swimmers who brave the chilly waters that flow in from the North Sea. But as soon as the sun makes an appearance, less hardy types also take the plunge.

Forget jetting off to Iceland – Wales’s very own Blue Lagoon is just as beguiling. The sea has flooded this former quarry, creating a glistening, seemingly bottomless pool that shines azure in the sun. Surrounded by sandy beaches and craggy cliffs, the lagoon’s depth makes it perfect for plunging into from the high cliffs (you can dive in as part of an organised group). It’s also a haven for coasteering and kayaking. 

Thanks to Scotland’s extremely lenient open-access laws, it’s possible to swim in nearly all of its atmospheric lochs – and Morlich is the perfect place to start. In the foothills of the country’s largest mountain range, it’s home to Britain’s highest beach, an invitingly sandy stretch where people can sunbathe, picnic or launch themselves into the loch’s cool waters. If watersports are more your thing, paddleboards, kayaks and canoes are available at the on-site activity centre.

There’s nothing more refreshing on a sticky, sweltering day in London than escaping to Hampstead Heath’s boundless greenery and plunging into one of its swimming ponds. The Heath has three swimming pools (ladies, men and mixed) which are open at various times of year. Originally dammed-off clay pits, the ponds are run by the City of London Corporation, but they have a loyal local following. In 2004, the regular swimmers took the corporation to court after they threatened to close the ponds. (They won – preserving this treasured London institution.) 

£4.70 for a one-day ticket. £2.80 concessions.

The Lake District’s epic lakes can get stupidly busy come wild swimming season. Kailpot Crag is on Ullswater’s quieter east side, which, crucially, doesn’t have a main road running alongside it. Walk from Sandwick or Howtown to the high, rocky cliff from which you can jump straight into the still, deep waters. There’s also a small lakeside beach if you’d prefer a more easy-going way in.

This tiny village in the Yorkshire Dales National Park is just as idyllically quaint as its name suggests. A track road opposite the New Inn takes you away from the chocolate-box stone cottages to the River Wharfe, where rocks and shingle lead down to a pool with a small rocky island and gentle rapids. Really want to make a splash? Have a go on the rope swing dangling from one of the waterside trees. 

This may be London’s newest wild swimming spot, but technically, it’s pretty ancient. In 2019 the park refilled its lost Georgian lake and converted it into a bucolic open-water hangout with a wooden jetty for jumping straight into the chilly waters. The long grasses, wet woodland and green hills sloping towards the water’s edge make the pool feel strangely secluded for an inner-city spot. Head to the café in the park’s charmingly ramshackle mansion for a post-swim snack.

From £3.95.
