Starting Point and Transportation

The journey begins in Cat Ba town, where pickup is included for those staying nearby. You can either meet at the tour office or arrange for a hotel pickup if you’re staying within 3 km—an arrangement that adds flexibility. The transfer is a short 10-minute bus ride that leaves plenty of time to settle in and enjoy the scenic cruise ahead.

Day 1: Sunset Cruise and Bioluminescent Plankton

As the afternoon unfolds, you’ll board a fancy boat around 4 pm or be picked up directly from your hotel. The cruise to Lan Ha Bay offers a picturesque transition from land to water, with the sunset views setting the perfect mood. Expect to cruise past some iconic islets and enjoy the fresh air while watching the horizon shift colors.

Once you arrive at your floating homestay, you’ll check-in for an overnight stay. The experience is quite different from standard accommodations—think of it as a cozy, floating retreat. Dinner is served on the homestay or boat, giving you a taste of local flavors with a laid-back, communal vibe.

The most talked-about activity of the night? Kayaking to see plankton light up the water. Tour guides will demonstrate how the tiny creatures glow when disturbed, turning the water into a shimmering sea of stars. One reviewer, Amanda, noted how beautiful the bioluminescence was during the kayak trip, which she described as “great.” It’s a peaceful, almost magical moment you won’t forget, especially when you realize you’re paddling through a natural light show.

However, Amanda also pointed out some downsides, including inconsistent management and some discomforts at the homestay—such as cleanliness issues and leaking ceilings during a rainstorm. These are reminders that rustic floating accommodations can vary widely in comfort, so temper expectations accordingly.

Day 2: Full-Day Exploration of Lan Ha Bay

Early mornings on the bay are quite special. If you’re an early riser, you’ll appreciate the dawn views and fresh air before breakfast. At 9 am, you’ll set out on a full-day cruise to take in the bay’s breathtaking scenery.

The route includes stops at Bat Cave, Dark Cave, and Bright Cave for kayaking. Each offers something unique—caves to paddle through, dark and light contrasting in the water, and plenty of opportunities to enjoy nature’s architecture up close. The guide will lead you through these caves, sharing insights into their formations and local stories.

The cruise continues further south, where you’ll encounter fewer travelers and more tranquil waters. Here, you can swim and snorkel in a calm lagoon, a perfect way to cool off after kayaking. Visiting a local fish farm adds an authentic touch, giving you a glimpse into the local fishing industry and the chance to buy fresh seafood directly from the source.

Lunchtime features a set menu on the boat, highlighting the fresh, local ingredients that keep the meal simple yet satisfying. The sundeck provides a great spot to relax and take in the views as the boat moves between islets like Pen Islet, Sailing Islet, and Frog Islet.

A highlight is a stop at Three Peach Beach, where you can jump into the bay for swimming and snorkeling—an activity appreciated by many for its fun and refreshing qualities. You’ll also visit a local fish farm, which offers an authentic insight into the region’s livelihood, and likely some memorable photos along the way.

Authentic Experiences and Challenges

Based on reviews, guides are generally knowledgeable, especially during kayaking trips. Amanda highlighted the “spectacular views” and the uncrowded routes taken by the second kayak company, which added a layer of authenticity and tranquility.

That said, some travelers experienced management inconsistencies, especially at the homestay. Amanda’s account mentions “no English spoken” staff and uncomfortable conditions such as a leaking ceiling and unclean rooms, which remind us that rustic stays can sometimes fall short of expectations.

This highlights the importance of setting realistic expectations: this isn’t a luxury cruise, but rather a chance to connect with nature and local life from a cozy floating base.
