The Earth is covered by a quarter of sea and ocean water, and humans only understand 5% of the aquatic environment, so there are also many most dangerous places to swim beside the safe seas that are allowed to operate. Here, I will list some of the most beautiful and strange-looking seas or lakes in the world, but they are full of danger to humans and some animals.
Most dangerous places to swim in the world
Monte Neme Lake
A lake of emerald green water can be found on Spain’s El Monte Neme mountain. Many social media influencers have come here to capture virtual images because of the lake’s surreal beauty.
Those that elect to swim in the pool, on the other hand, will become quite unwell, developing rashes, vomiting, and a variety of other symptoms.

El Monte Neme has been a tungsten and tin mining location with considerable deposits since 1915, with mining continuing until 2012, when the last mines were closed.
Toxic waste from decades of ore mining has contaminated adjacent regions, notably Lake Monte Neme, making the water unsafe for swimmers. Therefore, it deserves one of the most dangerous places to swim in the world.
Kawah Ijen Acid Lake
There is a 1 km wide lake filled with blue water in the Kawah Ijen crater in Java, Indonesia. Despite the fact that this lake appears to be serene and appealing, swimming in it is certainly not a good idea! This is the world’s most acidic crater lake as well as the world’s most dangerous place to swim.
In 2008, an explorer went out on the lake in a rubber boat to evaluate the acidity. Due to the presence of significant concentrations of sulfuric acid, the pH of the water near the lake’s margin is around 0.5, while the pH at the lake’s center is 0.13.
Boiling Lake, Dominica
Don’t put your toe in Dominica’s boiling lake if you’re planning a Caribbean vacation. Although it is located on a high mountainside in the Morne Trois Pitons National Park, it is not a pleasant hot spring. This lake is on the verge of boiling over.
This is effectively a submerged fumarole (an opening in the planet’s crust that emits water vapor as well as gases including carbon dioxide, sulfur dioxide, hydrogen chloride, and hydrogen sulfide). It is the world’s second-largest hot spring, with a width of 60 to 80 meters!

Although the water temperature varies from 82 to 92 degrees Celsius around the lake’s shore, the poisonous heat of the water exceeds 100 degrees Celsius in the hottest region of the lake. Two individuals drowned in the lake in 1900. After succumbing to asphyxia as a result of the abrupt discharge of volcanic gases, he died on the ground.
Hanakapi’ai Beach, Hawaii
Hawaii is a vacation fantasy, with its many beautiful beaches and sunny weather, but it also contains unsafe beaches where you should never swim. Hanakapi’ai Beach on Kauai is at the top of the list. To begin with, you must walk a challenging (but lovely) 2 miles to reach this beach.
Then, when you arrive here, you’ll notice that the water contains dangerous currents, that have caused several individuals to drown. Best of all, this beach has no sand in the winter, so it’s not perfect for a beach bum vacation. If you’re going trekking, avoid the water. This is really one of the most dangerous places to swim.
Samaesan Hole, Thailand
While Thailand has a lot to offer interested travelers and can be a terrific vacation spot, the Samaesan Hole is better left to the most experienced divers, if there are any. In the center of a busy shipping lane, it was around 280 feet deep and incredibly dark.
Strong currents add to the dangers of this dive location, which are compounded by the depth and lack of visibility. If all of this isn’t enough to make you want to swim here, the site is also a former military waste. According to AquaWorld, there are still unexploded bombs at Samaesan Hole.
Lake Victoria, Africa
Lake Victoria is a massive body of water that lies between Uganda, Tanzania, and Kenya. Millions of people live along its coasts and make a living from its resources. However, 5,000 people perish in the lake each year, making it the world’s deadliest body of water in terms of deaths per square kilometer.

The most serious danger in Lake Victoria is the unpredictably stormy weather, which may easily sweep up small ships in the area. A lot of the fishermen working on the lake don’t have life jackets, so it’s a disaster waiting to happen. A new text-message-based weather warning system, on the other hand, is helping to save lives.
Rio Tinto, Spain
This river in Spain is known for its history rather than for river rafting. Its material wealth (copper, gold, silver, and iron) drew so much interest in antiquity that it was dubbed “the birthplace of the Bronze and Bronze Ages.”
However, because the red river has been extensively dredged and mined, it has become extremely acidic, making it unsuitable for swimming. If you’re a science fan, it may be similar to an underground acidic ocean on Jupiter’s moon Europa, as it has amphibian bacteria living in it. So, if you enjoy science and history, go to Rio Tinto, but don’t go swimming because it seems to be one of the most dangerous places to swim in recorded.
Shark Alley, South Africa
If you’re looking for a snorkeling or whale-watching vacation, South Africa is a fantastic choice. Because Shark Alley, a canal packed with great white sharks, is just near Gansbaai’s coastline, the town calls itself the “Great White Shark Capital of the World.”
It’s a famous place for cage diving (where you’re enclosed in a large underwater cage with jars or bait to attract sharks). While you can cage dive in Shark Alley, swimming in these waters without special authorization is not permitted.
Citarum River, Indonesia
The Citarum River in Indonesia, like the Ganges, is severely polluted and has been dubbed the “dirtiest” river on the planet. It is extremely essential to those who live in and near huge cities like Jakarta, yet industrialization has drastically altered it.

Textile mills along the river’s banks discharged poisonous waste into it. Furthermore, despite the fact that it was also a source of water, the people who lived beside it utilized it as a dump. To accommodate all of the additional citizens flocking to the industries, there just isn’t an adequate waste management infrastructure in the neighborhood.
Some South Carolina, South Carolina Beaches
In general, swimming is fairly safe on South Carolina beaches. They do, however, pose certain possible risks. Rattlesnakes, for example, come at random on beaches: some emerge from the ocean, others swim, and yet others relax on the surrounding grass.

There are six kinds of venomous snakes in South Carolina, with many of them found on the coastal islands. They prefer to live on land, but they do occasionally live in swamps, on the beach, or in the ocean. Furthermore, the water in Myrtle Beach might be contaminated the day following a very strong rain.
To summarize above are 10 of the most dangerous places to swim in the world that people should stay away from because of naturally active substances as well as chemicals released from industrial plants or garbage from human domestic waste. Everyone needs to consult to avoid life-threatening incidents.
