Luon Cave - The Picture of Paradise

Luon Cave is an amazing spot in Halong Bay! If you're planning a kayaking adventure in Halong Bay, you should check out Luon Cave. It's perfect for a 2-day, 1-night, or even a 3-day, 2-night kayaking trip. The cave is a favorite among travelers because of its beautiful lagoon, tranquility, and the peaceful escape it offers from the hustle and bustle of the larger cruises outside the lagoon.

1. What is Luon Cave?

Translating to ‘Tunnel Cave’, Luon Cave sits about one kilometer away from the Amazing Cave in the center of UNESCO World Heritage-listed Halong Bay. Luon Cave is one of the most spectacular wet caves in all of Halong Bay, meaning that it is only accessible by kayak or local sampan boat. The actual ‘cave’ bit of Luon Cave is only about 60 meters long, opening with one mouth onto the ocean and the other end onto a glorious grotto, enclosed with high rock walls dressed with verdant trees.

2. What do I do at Luon Cave?

Being one of the most beautiful Halong Bay Caves, the natural splendor of Luon Cave and the environment around it gives it an amazingly tranquil atmosphere, one in which visitors to the cave love to unwind. The mouth of the cave looks almost man-made; cut out of a perfectly flat piece of rock, with several interesting rock formations almost dripping into the water from the cave ceiling above.

It is not so much the ‘tunnel’ part of Tunnel Cave that makes it a popular destination, but the open-air grotto that serves as its garden. 60 meters from the sea, Luon Cave opens up spectacularly into a picture of pure serenity. Jutting limestone walls enclose the magical area, where Benjamin fig trees, banyan trees, and orchids cling to the steeped and sheer mountain faces, with emerald water reflecting the color of the greenery around it.

Impressive kites and colorful kingfishers can be seen nesting in the trees high above, while some mischievous monkeys make their home here, swinging between the dangerous branches in search of fruit.

Luon Cave can only be explored by kayak and sampan boat during Halong Bay cruises. Although it is one of the more popular Halong Bay caves, the absence of big ships adds to the wonderful quietness of the cave and helps it retain its whimsical aura.

3. What is the history of Luon Cave?

Fossils found in Luon Cave affirmed its habitation by humans thousands of years ago; freshwater snail fossils indicate that they were farmed in small quantities by the original humans living in this area. Halong Bay’s caves were a good spot for habitation because of the shelter and cool air that they provided. Luon Cave, in particular, has a rich food supply within its brackish waters, with prawns, squid, cuttlefish, and snails flourishing, along with several varieties of birds attracted by the abundance of small fruits.
