Lemnap Blue Cave

Tanna's Blue Cave is a must-see attraction on the island's northwest coast. This stunning natural wonder is accessible by boat or car, and it's an easy swim into the cave.

To enter the cave, you'll need to swim a short distance. During low tide, you can easily swim under a rock ledge. During high tide, you'll have to swim underwater for a brief moment to get inside. The cave itself is spacious with a large hole in the roof that lets in a shaft of beautiful blue light, creating incredible photo opportunities.

You don't need to be a strong swimmer to enter, but if you're nervous about swimming underwater, it's best to visit during low tide. The cave's owners, Daniel and Rachel Talap, recommend checking with your tour operator for the day's tide schedule. Tours won't operate if the sea is too rough, as strong currents can push into the cave.

Once inside, you'll have plenty of time to explore. For the adventurous, there are platforms outside the cave for jumping into the water. If you prefer to relax, you can climb a ladder up the cliff to a small lookout area. Here, you'll find hammocks, a great view of the Pacific Ocean, and a chance to see the hole in the cave's roof from above. It's also a great opportunity to chat with the friendly local family who owns the property.

Some tours include food and refreshments, but it's best to confirm with your tour company about any additional extras.

If you don't book a tour, you can visit the cave on your own by boat, yacht, or 4WD. The entrance fee is 2,000 vatu per person, and it must be paid in cash. This fee is typically included in the price of a tour.

For a more immersive experience, the owners have recently built a bungalow on a ridge above the cave. You can book an overnight stay to get more time at the Blue Cave and explore other nearby attractions.
