Nestled on Chaweng Beach shore on the island of Koh Samui in Thailand, The Library Resort boasts minimalist-styled, luxurious suites, lush topiary, and an extensive collection of books for guests to peruse. Yet The Library’s most striking feature is the bright red pool situated against the ocean. Housing daybeds, Thai antiques, and a mini-library, The Red Pool is the resort’s most intriguing and appealing accommodation.

The Red Pool is perfect for those who have grown tired of the traditional pool experience. The aquatic destination looks blood-red from afar, though due to the mass of orange, yellow, and red tiles that cover the bottom, it becomes a beautiful mosaic of inviting color up close. Almost every room in the hotel provides a view of the pool’s fire engine red coloring against the sparkling blue ocean.

Unsurprisingly, The Red Pool has been featured on CNN and Tripadvisors’ lists of the world’s most spectacular hotel pools.

Though colorful pools are hard to come by, The Red Pool isn’t the only red-water tourist attraction in the world. The Blood Pond Hot Springs in Japan feature a naturally orange-red body of water that’s been around for centuries. Many believe that the Blood Pond Hot Springs are the oldest springs in the area.

While the Red Pool gets its crimson hue via tile, the Blood Pond is cherry-cheeked thanks to high levels of iron in the water. It’s also incredibly hot, coming in at more than 70 degrees Celsius. Locally referred to as “Chinoike Jigoku,” the Blood Pond is one of eight hot springs in the area referred to as “hell” or “jigoku,” as they are only for viewing and not for swimming. Many consider the Blood Pond the most spectacular and photogenic of the eight hellish hot springs.

While red seems to be the most visually bizarre liquid color, bodies of water also come in a variety of other shades, usually depending on the type and amount of minerals within the water source. The Yellow Hot Springs in Yellowstone National Park has garnered the patronage of many over the years due to its striking canary coloring. Lake Ngakoro in New Zealand has a cool green tone that’s also incredibly vivid and breathtaking.
