Swimming in nature or taking a dip in an open-air pool is one of the best ways to cool down during summer. If you’re planning something a little different to a visit to your local pool next summer, we’ve created a wild swimming map of the UK and Ireland so you can plan ahead and jump in.

Wild swimming has become increasingly popular over the past few years. Open-air swimming brings you closer to nature, and nothing beats swimming under the open sky. There are hundreds of serene locations across the country that provide ideal alfresco swimming conditions, but it pays to plan ahead so you get ahead of crowds that can descent in summer.

Wild swimming – safety first

As with any wild swimming, safety is incredibly important. Just be sure to stay safe in the water; don’t swim alone or under the influence of alcohol, stay close to the bank or shore, and you should be a strong swimmer. The water can be cold and depths can be unknown, so don’t jump or dive in.

Wise Living has rounded up 14 of the best wild swimming and open-air swimming locations across the UK and Ireland. It includes a mix of genuine wild locations, as well as more organised open-air pools if you fancy something a little less wild.

A renowned swimming spot in Ireland, the Forty Foot was made famous by James Joyce’s Ulysses, where character Buck Mulligan takes a dip at the once men-only bathing area.

Glanmore Lake on the Beara Peninsula, County Kerry, Ireland.

A calm, accessible lake freckled with rocky islets, guarded by the imposing Caha Mountains, Glandale is the sort of place you build a day around. Large, tree-lined, and equally excellent for walking, it’s just as good for forest bathing as it is for the real thing.

We don’t know just how many ‘Blue Lagoons’ there are the world over, but if they’re anything like this one it’s still not enough.

Pembrokeshire is a hub for wild swimming and it’s easy to see why looking at  the idyllic waters of the Blue Lagoon. The site was formerly a slate quarry until its channel to the sea was destroyed, resulting in the ultimate spot for adrenaline seekers. The Red Bull Cliff Diving World Series have been held here multiple times, making it the first British site to host the series, but those just wanting a paddle are catered for too.

Sister lake Windermere often gobbles up all the column inches, but for swimming Butter is the better ‘mere’ by miles. Voted one of the top ten views in the country in a 2017 poll, it’s motorboat-free and boasts several small pubs perfect for a post-plunge pint.

The temperatures can be, er, invigorating, but for determined dippers it’s one of the most scenic swims you’ll find.

Goldiggins Quarry, Cornwall

A pristine pool of sun-soaked stillness ringed by a rocky amphitheatre, this disused mine is calm, cool, and often deserted.

There are different jumping off points for every level of bravery (take care though) and the water is deep and crystal clear. There are even a few fish, though how they got there we really don’t know.

Tinside Lido, Plymouth

Tinside Lido, Plymouth.

Outdoor swimming doesn’t have to be in the wild, but nor is this any normal pool. A Grade II-listed, art deco, salt water lido dating from the 1930s, Tinside occupies a rocky outcrop looking straight out over Plymouth harbour.

It’s not quite an infinity pool, but at the right angle it looks like one.
