This cave is located off a water stream at Kuala Kubang Badak and north of the main Langkawi island. You can reach there by taking a boat ride from Tanjung Rhu Jetty area. Once there, you will need to climb for about 20 minutes through hard and thorny vegetation to reach the cave. It is estimated that the cave and the surrounding area was under the sea thousands of years ago. It is indicated by the many sea shells on the walls of the cave. The entrance is small and by the side of a huge limestone outcrop. A passage leads down to the chambers below. The passage gets narrower and darker as you climb down the stairs. And inside there are thousands of bats (known as Asian roundleaf bats) hanging from the ceiling and flying around as you can see them in flash lights. It is estimated that the Gua Pinang has close to 10,000 bats which is more than any other caves in Langkawi. You can see huge formations of stalactites and stalagmites in the cave as well as many different types of insects, lichens etc. It takes about 20 minutes before you can see sunlight again as you come out from another side, but it takes much longer to explore the whole cave. An estimate says that Gua Pinang is about three times the size of Gua Kelawar (Bat Cave), but still due to difficult access, it's hardly visited by tourists.
