What's the attraction?
The lure of the big blue – and the steely grey and choppy – is getting stronger. If "open water" sounds a bit daunting, don't worry; there are plenty of specialist companies willing to hold your hand as you dip a tentative toe in. Swimtrek (01273 739713; swimtrek.com) was launched 10 years ago by Channel swimmer and coach, Simon Murie. Then, the number of people booking a swimming holiday was in the hundreds. This year, Swimtrek expects to take around 4,000 swimmers on holidays ranging from a week-long island-hopping trip around the Sporades in Greece to shorter breaks in Mallorca and Slovenia.
Other companies offering swimming holidays include The Big Blue (0113 2169 434; thebig blueswim.com) for trips in Greece and Gone Swimming (01244 940 740; goneswimming.co.uk) if you fancy a "Wet Weekend" in Wales. And there are dozens of opportunities to take the plunge in more controlled environments too, with learn-to-swim and improvement holidays in pools around the world.

In hot water
In Iceland, they take their bathing so seriously that the word laugardagur means both Saturday and pool- or hot-springs day. The Blue Lagoon (00 354 420 8800; bluelagoon.com) is one of the country's most renowned attractions, where the mineral-rich water is a balmy 37–39C. Entrance costs from €33. Iceland also has numerous geothermally heated swimming pools, 13 around Reykjavik alone. The Laugardalslaug Geothermal Pool (00 354 411 5102; reykjavik.is) is the largest in the country with an Olympic-sized indoor pool as well as an outdoor pool, a whirlpool and a steam bath. Entrance costs IKr550 (£3.40). Swimminginiceland.com lists more hot springs and geothermal pools around the country.

The tour departs from Beccles in Suffolk on 10 and 17 August and ends in Norwich, with plenty of swimming in the Norfolk Broads in between.
A whale of a time
Thousands of beluga whales summer in the waters of the Hudson Bay and Churchill River in Canada each year before migrating north to the Arctic Ocean. Discover the World (01737 214250; discover-the-world.co.uk) offers the chance to jump into the water and snorkel with them. The five-night trip in July and August costs from £1,553 per person and includes return flights between Winnipeg and Churchill, transfers, five nights' accommodation, half-day tundra buggy tour, a tour of Churchill, a three-hour beluga whale-watching cruise and a two-hour beluga-watching zodiac cruise; international flights not included.

Slovenian Martin Strel, aka Big River Man, was the first man to swim the five great rivers of the world: the Amazon, Yangtze, Paraná, Mississippi and Danube. He has since set up Strel Swimming Adventures (07700 061236; strel-swimming.com) with his son, Borut. They run swimming holidays in Slovenia, Austria, Croatia, Montenegro and Lake Powell, Arizona. The four-day Slovenian Lakes and River trip takes you to the lush forests and glacial lakes of Triglav National Park to bathe in the Kozjak waterfall.

As you trek along the Costa da Morte (Coast of Death) you can veer off the path to head down to wild beaches and jump into the Atlantic breakers. The six-night trip costs from €539 per person half board, excluding flights.
Nicole Kidman swam in the remote waterfalls and natural pools of the El Questro Wilderness Park in Kimberley, Western Australia (00 61 3 9426 7550; elquestro.com.au) while filming Baz Luhrmann's Australia.

Swim Barbados Vacations (swimbarbadosvacations.com) is staging two open-water sea races on 6-7 July and 26-27 October. The swimming festival, featuring a 1.5km race and a 5km race, plus watersports, a beach barbecue and live music, is open to swimmers from across the world. Entry is US$18 (£12); closes 5 July.
"Swimming is so much more than plodding up and down the lane of your local pool. In open water, no two experiences are the same. My favourite swim is the Hellespont in Turkey which divides Europe from Asia and which Leander made famous in Greek mythology by swimming to his lover Hero every night. Lord Byron repeated the feat in 1810. This 4km swim starts at Gallipoli and finishes near the ancient city of Troy." – Simon Murie, founder of SwimTrek
