Nestled on Bo Hon island, Luon Cave is surrounded by breathtaking scenery. Opposite the cave, you’ll find Con Rua islet, and to the right of the island is the majestic Sky Gate.

How to Explore
To explore Luon Cave, you can only do so by boat. As cruise ships and tour boats are too large to enter, most travelers choose to take a local Sampan boat, which comfortably accommodates 10 to 15 people. This guided tour within the cave takes approximately 20 minutes and offers a unique perspective on its mesmerizing beauty.
If you prefer a more independent experience, renting a kayak and exploring the cave on your own is also an option. The cave stretches approximately 60 meters long, and depending on the tide, its height can vary from 2.5 to 4 meters.
