The cave connects to the ocean with a “tunnel” water cave. To get inside, travellers have to row a kayak or take the rowboat. Inside the closed cave, an ecosystem with lush plants, giant trees, fragrant orchids, monkeys and a rich marine life underwater appear in front of your eyes. Locals believe there was village life here due to the discovery of many fresh-water snails which has been fossilized on the grotto’s wall.


It is recommended for tourists to travel around the Bay by boat or book a cruise to stay on the water for a night. You can look for “Ha Long Bay Cruise” as a preferred option. They would include Luon Cave on the agenda. It takes only 20 minutes for a tour in and out of the cave. However, if you are rowing your own kayak, you definitely want to standby for a good floating relax session in the middle of a magnificent harmony between great mountains, blue sky, green plants and fresh air. Some Halong Bay tourism agency includes Luon Cave visiting in the agenda. Nevertheless, you can rent a kayak from Cat Ba island and row your way to the beautiful cave and enjoy yourself with nature.
