Fantastic Activity

YANNICK_C, Mar 2026
We joined "Captain Jacks(parrow)" and his friendly crew for an amazing full day long-tail boat tour discovering 4 islands near Koh Lanta. The highlight was certainly discovering Emerald Cave and the amazing and immersive experience that it offers despite the crowds. The crew did absolutely everything they could to entertain our group throughout the tour and cooked an amazing lunch on the beach! This bunch of young lads were great ambassadors to their country - funny, respectful and helpful. Highly recommended to others in quest of a water adventure! Cheers

A Great Day

This trip was exceptional. I was picked up at my hotel, no hassle to find a ride to a meeting place. The boat ride was exciting, the snorkeling just beautiful and the swimming through the cave and into the isolated beach among the cliffs, was nothing less than breathtaking. I am a solo traveler yet was part of a fun group of people. The tour guides worked hard to make sure we were all safe also. I recommend this trip.

This tour was very good, however we where a bit unlucky with the weather, as it was overcast and rainy. It didn't affect the tour though as the water was still fine, the beaches where great and lunch was al fresco on a lovely beach! Well worth recommending!

Excellent 👌

Response from Host, Apr 2024

Dear Mohamed_G Thank you so much for your fantastic review! We're thrilled to hear you had an excellent excursion and that our crew was top-notch and kind. We're especially happy to hear the guide helped your daughter through the cave – that's what we're here for! We hope to welcome you back on another tour soon.

Bien qu'ils soient énormément...

Bien qu'ils soient énormément touristiques, nous avons apprécié les sites visités, tout particulièrement la cave d'Emeraude. La plage était magnifique et le repas délicieux. Par contre, dans l'offre, il était indiqué 45 minutes de bateau longue queue pour rejoindre le premier site et nous avons mis 1h30 !!! La mer était un peu agitée et l'eau rentrait dans le bateau, toutes les affaires étaient détrempées sauf si vous aviez la chance d'être au fond. Notre choix s'était porté sur un bateau longue queue en pensant que nous allions être peu de monde mais au final nous étions plus de 20. Si vous souffrez du mal de mer, nous vous déconseillons de choisir les bateaux longue queue, notre fille a vécu une galère...
