We saw Maya Bay and Phi Phi Island, where we stopped for lunch and had a swim in the water. We also stopped for snorkelling, and then visited Bamboo Island. The tour was very well organised from start to finish. We were given free water, Coca-Cola, watermelon, and pineapple. Our tour guide was brilliant, and the staff on the boat were excellent. No complaints at all just beautiful photos and plenty of memories ❤️ Highly recommend it!”

11.4 Islands Tour by Speedboat with Snorkeling

★★★★★★★★★★3.9 · 21 reviews · 8 hours · from $51

Review of Koh Lanta’s 4 Islands speedboat tour, including Emerald Cave, snorkeling, lunch on Koh Kradan, costs, crowds, and practical tips.

“Liian kiire joka paikassa ja liikaa ihmisiä. Opas epäselvästi kertoi ajan paikoissa. Snorglaus paikkassa ei mitään katsottavaa ja ihmisiä todellakin liian paljon. Vieri vieressä kymmeniä ihmisiä pienellä alueelle . Ja vielä opas unohti laskea porukat kun lähdettiin luola uinilta ja yksi asiakas jäi matkasta. kuski huomasi virheen ja äkkikäännös takaisin luolille. Mies löytyi luolien edestä ja onneksi oli pelastusliivit päällä, mutta paikalla oli enään kaksi pitkähäntävenettä. Todella huonoa asiakaspalvelua.”

“Departure was later than posted. Safety aspect can be improved as it felt more than 20 person in the long-tail boat at a time was too many. Some of us missed the Emerald Cave tour as the tour guide did not wait for those who last left the long-tail boat hence we have to head back to the boat.”
