Starting Point and Transportation

The tour begins in Cat Ba town, where you can either meet at the tour office or be picked up from your hotel within 3 km. We appreciate the convenience of hotel pickup, especially after a day of travel or exploring the island. The transfer to the cruise is quick—roughly 10 minutes—allowing you to settle into the experience without long delays.

Day One: Welcome to Lan Ha Bay

As the day winds down, you’ll cruise towards Lan Ha Bay, enjoying views of the bay’s rugged limestone formations and tranquil waters. The highlight? Watching the sunset while sipping drinks on the boat’s deck; a perfect moment to unwind and soak in the scenery.

After arriving at your floating homestay, you’ll check in to your room. Expectations here are mixed—some reviewers mention comfort and others note cleanliness issues, like a room with urine smell or a leaky ceiling during rain. Be prepared for a basic stay that’s more about the experience than luxury. Dinner is served aboard the floating home, giving you a chance to savor local-style meals while floating among the islands.

Night Kayaking and Plankton Lightshow

One of the tour’s standout moments is the kayaking trip at night to observe the bioluminescent plankton lighting up the water. We loved the way the tiny organisms glow when disturbed, creating a starry effect in the water that’s hard to describe. It’s a mesmerizing sight—almost like paddling through a galaxy of tiny stars. The tour guide’s expertise helps make this a safe and enjoyable activity.

A reviewer notes that the kayak trip with bioluminescent plankton was a real highlight, though they also mention some frustrations with the management—such as inconsistent company handling and language barriers at the homestay. Still, the unique experience of seeing this natural light show makes it worthwhile for those open to some adventure.
