Water flows into the lake, but doesn’t have an outlet to drain out of. The extreme waters of Tanzania’s Lake Natron are as deadly as they are beautiful. But if you’re looking for a slightly less-thrilling day at the lake, feel free to dip your toes or swim around the opening to Texas’ second largest fully submerged cave. Only researchers with proper permits are allowed to explore the depths of Jacob’s Well, due to its high fatality rate. About 6,000ft of passages have been documented going down to well till date. The elaborate network of underwater caves stretching endlessly down the well plunge over 100ft down. The stifling Texas heat makes Jacob’s Well a welcome escape to divers to jump into its cool, deep waters-some, to their deaths.

Needless to say, jumping into this misty wonder is not a great idea, unless severe burns sounds like a good time. Nick-named the Boiling Lake, this lake is a far cry from cool and breezy, in fact, it’s almost boiling hot.įuelled by the lava underneath, this flooded fumarole (a crack or a hole in the Earth's crust), has a bubbling maelstrom of water in the centre and emanates a thick cloud of steam, which ominously surrounds it. There are many mountain lakes atop the Watt Mountain in Morne Trois Pitons National Park, but there’s one that’s quite unlike the rest.
