From a distance, the Cypress Creek opening resembles a dark sink hole.
While some dare to jump into the abyss, others take things a step further by diving beneath the surface.
A series of underwater chambers lie beneath the US spring.
While the pool spans just 3.7m in diameter, it is more than 37m in depth.
WATER MYSTERY: More than nine people have perished in these waters
Diving to the bottom of Jacobs Well can take more than five hours.
To touch the spring floor, divers are forced to swim through a number of narrow passages.
This difficult task is rewarded with a breathtaking view towards the surface – but it comes at a big risk.
Even some of the most experienced divers have lost their lives at the location.
The haunting passages have become known as “one of the most dangerous diving spots in the world”.
They have claimed the lives of more than nine people who have dared to explore their depths.
The way out is especially dangerous, as there is said to be a fake exit that has trapped and killed at least one explorer.
As it is extremely tricky to work your way through the chambers, only licensed SCUBA divers are allowed down.
The springs reputation doesnt stop thousands of visitors taking a dip every year.
Those who visit Texas have the option to book a tour to the Country Park attraction.
This doesnt always involve setting foot in the waters.
Many tourists have left reviews of enjoying the wildlife in the region.
Turtles, sunfish and salamanders are among the creatures you can see if you visit.
