Several interesting limestone caves are located in the Andamans, home to swiftlet birds, bats, sea snakes and other endemic wildlife. The large cave system on North Andaman Island is mainly an unexplored and undeveloped attraction, but the caves of Baratang Island offer easy access by boat for tourists to visit and see the interesting rock formations formed by erosion. Other limestone caves have been created due to the action of the ocean, which has been eroding sea caves along the coastline on Neil and Little Andaman islands for thousands of years. Exploring the different limestone cave locations offer visitors a glimpse of the geological uniqueness of the Andaman Islands.
