In these dog days of summer for a good chunk of the world (no offense to dogs; it's just an expression), we thought it would be an appropriate time to check out some of the unusual ways people can beat the heat.
We begin with the world's largest swimming pool, a highlight of the San Alfonso del Mar resort in Algarrobo, Chile. Completed in 2006, the artificial lagoon occupies nearly 20 acres and is more than half of a mile long.
If you happen to be in Bali, you'll be within reach of the Hanging Gardens Ubud swimming pool. Perched high atop a jungle drop, the split-level pool has an "infinity"-horizon edge and boasts a wall of solidified volcanic ash. Nice swim, if you can get it.
If you skipped Bali and headed for Turkey on your vacation instead, you might be able to dip a toe in the famous travertine pools in Pamukkale. Travertines are terraces of carbonate minerals left by the flowing water.
Who says you need good weather to swim? In good or bad outdoor elements, the splashy fun remains the same inside Tropical Island, the biggest indoor water park in the world, in Brand, Germany. It was built inside a former airplane hangar.
New York may have a floating beach outside its collective window, if City Beach NYC comes to fruition. The idea will be to build a beach on a barge in the Hudson River. Organizers hope to launch the floating fun spot by 2016, if they can crowdfund their way to the starting capital.
From a planned barge project to one that's been floating for eight years, we see the Josephine Baker swimming pool on the Seine in Paris. It was named after the American artist and civil rights activist who died in Paris as a French citizen.
Not to be outdone, Germany too has made creative use of a barge. Shown here, Berlin's futuristic Badeschiff public bath floating on the Spree.
Here's another infinity pool that might be a tough swim for those afraid of heights. It sits atop the Marina Bay Sands hotel towers in Singapore.
Surf's up, or at least it will be. The world's first publicly accessible artificial surfing lagoon is planned for the village of Dolgarrog, in the Conwy Valley of North Wales. The Surf Snowdonia park will generate waves up to 6 feet high in a pool nearly 1,000 feet long.
Of course, there's no law that says swimming has to be done in warm weather. You could be surrounded by snow and still take a nice dip. Here people enjoy a therapeutic soak in the mineral hot springs at Banff Upper Hot Springs, Banff National Park, Canada.
