Nestled in the heart of Lan Ha Bay, the Dark and Bright Cave is a natural wonder that captivates visitors with its stunning beauty and unique features. This blog post will take you on a journey through this remarkable cave system, highlighting its key attractions and providing useful tips for your visit.
Get to know about Dark and Bright Cave
Dark and Bright Cave sits in the Cat Ba Biosphere Reserve, right where Halong Bay meets Lan Ha Bay. This special spot combines the best of both bays – you’ll see Halong’s famous rock formations and Cat Ba’s rich plant and animal life.
Near the cave, you can visit fishing villages where locals live in harmony with nature. They make a living from the sea while also helping to protect the marine environment.
The cave itself formed over millions of years. It’s what geologists call a “frog-jaw-shaped cave” because part of it is underwater while the ceiling stays above sea level. This unique shape lets visitors explore the cave by boat or kayak.
Dark and Bright Cave is actually two caves in one. The Dark Cave is deeper and narrower, often filled with water, so visitors can’t go inside. The Bright Cave is bigger and more welcoming. It’s about 3 meters high, 4 meters wide, and 100 meters long. The water level in the Bright Cave changes with the tides, but it’s usually open for visitors to explore.
The area around the cave is full of natural beauty. You’ll see monkeys playing in the trees, big fig trees providing shade, and colorful orchids blooming on the rocks. If you look closely at the cave walls, you might even spot ancient snail fossils from thousands of years ago.

Why you shouldn’t miss Dark and Bright Cave?
A natural wonder shaped by time
When you enter Dark and Bright Cave, you’ll see countless stalactites hanging from the ceiling. These formations look like stone icicles, created drop by drop over millions of years as water slowly deposited minerals. The stalactites come in all shapes and sizes, making the cave ceiling look like a mysterious underground forest.
A tunnel through the mountain
The cave’s arched ceiling and dark interior create a tunnel-like feel as you travel through it. As you move through this 100-meter passage, you’ll feel like you’re journeying to another world.
A hidden paradise
At the end of the cave, you’ll find a surprise – a peaceful lake surrounded by tall limestone cliffs. The mountains around the lake are covered in lush plants, including beautiful orchids. This green oasis is a stark contrast to the dark cave you just passed through.
Two caves in one
The Dark and Bright Cave system is actually made up of two separate caves. The Dark Cave lives up to its name – it’s 100 meters long and very dark inside. You’ll need a flashlight to explore it. The Bright Cave is shorter but filled with natural light that comes in through holes in the rock. This makes it feel almost like a natural cathedral.

What to do in Dark and Bright Cave
Kayaking to discover the cave
Kayaking is a popular way to explore Dark and Bright Cave. Many cruises provide kayaks and safety gear, along with a guide to help you navigate.
As you paddle through the cave, you’ll see the limestone formations up close. The bright part of the cave offers clear views of the rock walls and water, while the dark part provides a thrilling adventure.
Keep in mind that kayaking can be tiring, especially if you’re not used to it. Wear comfortable clothes and shoes that can get wet, and don’t forget sun protection.
Take a boat tour
If kayaking isn’t your thing, you can still enjoy Dark and Bright Cave on a small boat tour. These tours take you through the cave system, allowing you to see all the sights without the physical effort of paddling.
A boat tour is a great option for families with small children or anyone who wants a more relaxed experience. Your guide will point out interesting features and share information about the cave’s history and formation.
Admire how seawater erosion affects the limestone foothill
The limestone rocks in Halong Bay have been shaped by seawater over millions of years. In Dark and Bright Cave, you can see this process up close. Remember to look but not touch. These formations are delicate and need to be preserved for future visitors.
Look for interesting patterns and shapes in the rock walls. These were all created by the constant action of water against stone. It’s like seeing a giant natural sculpture that’s still being carved today.
Discover sparkling stalactites in the cave
One of the most impressive sights in Dark and Bright Cave is the stalactites hanging from the ceiling. These pointed rock formations grow very slowly over thousands of years.
In this cave, many stalactites have crystal formations that sparkle when light hits them. It’s like nature’s own chandelier. Take time to look up and appreciate these natural wonders.
Watching the sunset on the sea
For a perfect end to your visit, try to time your trip so you can watch the sunset from the cave entrance. As the sun goes down, the sky turns beautiful shades of orange, pink, and purple.
You can watch this show from a boat near the cave mouth. The calm water reflects the colorful sky, creating a 360-degree sunset experience. It’s a peaceful and beautiful way to end your adventure.
Exploring a green valley inside the cave
As you move through the cave, you’ll come to a surprising sight – a green valley hidden inside the rock. This area gets enough light for plants to grow, creating a lush oasis.
You’ll see different types of plants that have adapted to grow in this unusual environment. The green leaves create a beautiful contrast with the dark rock walls. Take a moment to enjoy the cool, fresh air and the peaceful atmosphere of this hidden valley.
