Krabi 4 Island Sunset Snorkeling Cruise + Bioluminescent Swim

2.Krabi 4 Island Sunset Snorkeling Cruise + Bioluminescent Swim

★★★★★★★★★★5.0 · 1,861 reviews · from $130Top rated

Spend six to seven hours aboard a traditional Thai junk with Michael and his crew, visiting Ko Ya Wa Sam, Chicken Island, and Poda Island. Snorkel, kayak, paddleboard, eat a Thai buffet, watch the sunset, then swim among glowing plankton near Phra Nang Cave Beach. Transfers from Ao Nang and Railay are included.

“DO IT!!! Absolutely amazing day, excellent snorkeling spots, even saw a shark! The boat is big enough, not a big crowd on-board which is a plus. All 4 islands were beautiful, dinner served was of good quality. Very good visibility for snorkeling, can paddle as well if you prefer. The sunset was absolutely breathtaking and is worth everything. Snorkeling with bioluminescent planton was probably a once in a lifetime experience, I highly recommend it. The crew was just amazing, they take care of photos and videos (included in the price) as well. The boat runs with sunflower so it's a greener alternative than any other speedboats departing from Krabi. Don't…”

★★★★★★★★★★5.0 · 987 reviews · from $145

Board at Cayman Islands Yacht Club for a 20-minute night boat ride to Bioluminescent Bay. Crew members such as Michael, Thomas, Mike, Alton, Sean, and Elton provide equipment, wetsuits on some trips, water, and soda.

“Michael and Thomas were fantastic hosts! The boat is new, spacious, and incredibly comfortable — even featuring an upper deck perfect for stargazing. The bioluminescence was absolutely magical and made for one of the most unforgettable night swims I’ve ever experienced. This is truly a must-do excursion for anyone visiting the area!”

Launch from 951 Kiwanis Island Park Road near Merritt Island for a two-hour guided night kayak trip. In summer, look for blue-green dinoflagellate glow.

“Sean was the best guide we could have had for my family! He totally geeked out with the biology of how bioluminescence works and why it happens. I mean right down to the molecular details!! It was awesome! My 16 yo son was captivated: masking questions and bantering with Sean. It was so great to see and he didn’t even want to go on this kayak! Sean was funny and engaging with the whole group, paddling backwards for most of the trip making sure we all were together and knew everything that was going on around us from the manatees to the mullets swimming and darting like lightning flashes around…”

The experience was amazing, and Alex explained everything behind the sparkling water. He also showed us some constellations! The pickup and drop off process was also seamless.
