Limestone Caves in Andaman and Nicobar Islands are located on the Baratang Island that had been hidden from the world for a long time now. The island is home to Jarawa tribe, the most dangerous tribe in the world. The once-forbidden island is rich with dense jungles, mud volcanoes, mangrove jungles, and of course, limestone caves. Only recently, the ministry opened its gate to the gorgeous island to promote tourism on the island. These marvelous Andaman limestone caves are some million years old. Inside the caves, you will find conical rock-like structure protruding from the floor of the caves. These formations are called Stalagmites which is the creation of single-celled algae called cyanobacteria. It is fascinating to see how beautifully these rocks have been arranged inside the cave, the flowy calcium deposits in the form of waves look like an artwork. You will find yourself gaping at the structures inside the cave. It is almost unbelievable how nature is capable of conceiving such an ecstatic thing.
