A Sunset Cruise and Bioluminescent Swim in Krabi: An Authentic Beach Day

If you’re dreaming of exploring Krabi’s famed coastline, this 4 Island Sunset Snorkeling Cruise offers a perfect blend of adventure, relaxation, and unforgettable sights. For around $116 per person, you’ll spend roughly six hours hopping between some of the most scenic islands near Railay and Ao Nang, with plenty of opportunities to snorkel, paddleboard, kayak, or simply soak in the views. The highlight? An evening swim in waters glowing with bioluminescent plankton—a truly surreal experience that you won’t forget.
What we love about this tour is how it balances active fun with laid-back comfort. The crew is praised for their friendliness and expertise—making snorkeling accessible even for first-timers—and the boat itself is spacious, stylish, and equipped with all the gear you’ll need. Plus, the delicious Thai buffet dinner prepares you for a magical night, especially when you get the chance to swim in the glowing waters after dusk.
One thing to keep in mind is that this tour requires good weather—like most boat trips in tropical waters, it can be canceled if the sea gets too rough. Also, while most travelers find it perfect for a diverse group, those seeking a very quiet or private experience might find the group size (up to 24 people) a bit lively. But overall, this tour suits most visitors eager to combine island hopping, snorkeling, and a bit of magic into one memorable day.

What Makes This Tour Special?
This tour offers a well-rounded day exploring Krabi’s scenic coastline, with plenty of time to enjoy snorkeling, paddling, or just relaxing on the teak-decked boat.

One reviewer highlighted that the crew “really helped you get through the first-time jitters,” which makes this tour perfect for beginners or those who aren’t confident swimmers. They even carry guests around with a buoy if needed, ensuring everyone feels safe and comfortable.
The Itinerary: Why Each Stop Matters
The day is packed with five stops, each offering distinct scenery and activities.
First, at Ko Ya Wa Sam, you’ll find pristine coral reefs teeming with marine life. The reviewer Julianna called it “one of the best snorkeling spots,” with “plenty of marine life and beautiful coral.” Spending ample time here means you’ll get to see a vibrant underwater world, which is especially welcome if snorkeling is your main goal.
Next, a visit to Koh Si and Ko Ta Ming provides more opportunities to snorkel, though the exact stops may change based on conditions. The flexibility means your guide can find the best spots for the day’s weather, which can be a real advantage.
Chicken Island, famous for its distinctive rocky outcrop, becomes the perfect spot for swimming, paddling, or just soaking up the sun. One guest appreciated the “not crowded” feel and mentioned that the cocktails and food were “also good,” emphasizing the relaxed vibe.
Poda Island is where you’ll enjoy a Thai buffet dinner as the sunset paints the sky. The setting is idyllic, with a small private beach that some can paddle to—perfect for a post-dinner swim or photo session.
Finally, as darkness falls, the bioluminescent plankton at Pranang Cave Beach put on a magical display. The reviews rave about this being “the most magical experience,” with one guest describing it as “incredible” and “unforgettable.” It’s a rare chance to see this natural light show, and it caps off the day beautifully.
What’s Included and What’s Not
The tour is notable for its inclusiveness. You’re provided with premium snorkeling gear (including prescription masks), kayaks, paddleboards, and life jackets. Snacks, fresh fruit, and free-flowing drinks (water, juice, soft drinks) keep you refreshed, while the Thai buffet dinner caters to vegetarians and vegans alike.
The bar offers alcoholic drinks for purchase, and amenities like a waterproof bag and USB charging ports make your day comfortable and convenient. The boat is equipped with a quality music system and spacious seating, perfect for relaxing between activities.
Keep in mind, hotel transfers are not included, so you’ll meet the tour at designated points in Ao Nang or Railay. This setup works well for most travelers, especially since the meeting points are central and easy to find.
