Recently, we talked about the unusual underground lake Hamilton Pool. Now we will focus on the most famous underground river in the world, which in the past year, according to the results of a worldwide vote was recognized as one of the new seven wonders of nature.
The length of the river is 8 kilometers, is the world's largest underground river, is navigable: it is possible to boat for a distance of 4 km from the sea. However, river cruises at such a distance are not allowed here due to security reasons tourists because in the depths of the cave, on which the river flows, feel the lack of oxygen. However, tourists are still there, where to swim: boats are allowed on the 1.2 km in the depths of the cave, where you can admire the stalactites and stalagmites. At this distance from the sea, plenty of oxygen, because periodically, the dome of the cave there are holes, which let in daylight and air. The cave through which an underground river flows, is one of the largest in the world.
In addition to the trip down the underground river, tourists can explore the unique flora and fauna of these places, for example, here you can find the rare mammal - sea-cow, and also to see the unusual bearded pigs, monitor lizards and their animal, at once reminiscent of cat and bear, tourists and call them "cat-bear".
The best time to visit the underground river from January to may when the sea is more calm and a lot of sun.
