Places You Should NEVER Swim

[Narrator] As temperatures start to climb, there's no better way to cool down than to take a dip in the pool. But be careful, because not all bodies of water are made for swimming. Some of these lakes, rivers, and pools may look inviting, but taking a dip in them might be the last thing you ever do. From pretty pools that are actually brimming with acid, to flooded holes that are impossible to escape, let's dive into some swimming spots you should approach with caution and others you shouldn't approach at all. (upbeat music)

Bleach Bath: Lake Natron in Tanzania is a real-life example of a place that can turn living things into stone. The lake's high salt content and alkaline environment make it extremely inhospitable for most life forms, including migratory birds, which can become coated in salt crystals and mummified alive.

Narrow Escape: Jacob's Well in Texas is a karstic spring connected to an underwater cave system. Divers who explore the cave face the risk of getting lost in narrow tunnels, sometimes having to remove their oxygen tanks to squeeze through tight spaces. Several divers have lost their lives in Jacob's Well due to getting stuck.

The Underwater Labyrinth: The Eagle's Nest Sinkhole in Florida is a flooded sinkhole with a network of caves and tunnels. Cave divers are drawn to this location, but it's easy to get lost in the dark, labyrinthine passages. Over the years, many divers have lost their lives in this underwater maze.

Black and Blue: The Blue Lagoon in the UK may look beautiful, but it's a former limestone quarry filled with highly alkaline water. Swimming in the lagoon can lead to skin irritation, stomach problems, and chemical burns. Despite warnings, some people still risk swimming in these dangerous waters.

Yellowstone's Secret Weapon: The Grand Prismatic Spring in Yellowstone National Park is the third largest natural hot spring in the world. Its colorful appearance is due to different types of bacteria that thrive at different temperatures. The extremely hot water can cause severe burns, and tragic accidents have occurred when visitors disregarded warning signs and entered restricted areas.

Hot And High: The Strokkur Geyser in Iceland is a powerful geothermal feature that shoots boiling water and steam high into the air. Jumping into this geyser would be extremely dangerous, as it could lead to severe burns or fatal falls.

Whirlpool Worry: The Naruto Strait in Japan experiences strong tidal currents that create large whirlpools. While boats can navigate these waters safely, swimmers can be overpowered by the currents and dragged out to sea. Tragic incidents have occurred when individuals ignored warnings and ventured into these dangerous waters.

Risky Reservoirs: Manmade reservoirs like Lake Berryessa and Ladybower Reservoir may seem inviting, but they have hidden dangers, including powerful currents near spillways. Swimming near these areas can lead to dangerous situations, and some have tragically lost their lives by ignoring warnings.

Big Hole: The Big Hole in South Africa is a former diamond mine that's incredibly deep. The walls of the pit are sheer and difficult to scale, making it a hazardous place to swim. In one incident, a dog fell into the pit and was unable to escape, highlighting the dangers of this location.

Life's a Beach: Hanakapiai Beach in Hawaii may appear idyllic, but it's known for its deadly rip currents. Strong ocean currents make swimming here extremely hazardous, and many visitors have been swept out to sea. Despite warning signs, some continue to underestimate the danger.

Colorful Caution: Lake Hillier in Australia and the crater lake in El Chichon, Mexico, both have vibrant colors due to natural factors. However, these colorful lakes can be highly acidic and contain dangerous chemicals, making them unsuitable for swimming.

Big Pit: The Berkeley Pit in Montana is an abandoned copper mine filled with toxic water. The water is highly acidic and contains harmful metals. Even birds have been killed by the water's acidity, emphasizing the dangers of swimming in this pit.

Remember, when it comes to bodies of water, it's essential to heed warning signs, follow safety guidelines, and prioritize your well-being. Some beautiful-looking spots can hide dangerous secrets, so always exercise caution and prioritize safety when swimming in natural environments.
