4.Koh Lanta: 4-Island Adventure Tour to Emerald Cave

★★★★★★★★★★4.6 · 128 reviews · 7h 30m · from $51

Spend 7.5 hours island-hopping by speedboat from Koh Lanta. Swim through Koh Mook’s 80-meter Emerald Cave, snorkel at Koh Kradan and Koh Chuak, then relax at road-free Koh Ngai. Guides such as Bon and Non lead the day in English or Thai.

“We couldn’t see much when snorkeling due to weathercondition unfortunately and there were some jellyfish in the water. Just bad luck and nothing to do with TIN who did a great job and maybe because of that they took the eastern side back home so we got to see Mangrove and monkeys. Last time we got picked up at beach but now by car to Saladan. Prefer beachpickup before a bumpy ride but on the other hand then we wouldn’t have seen the Mangrove and monkeys on the eastern side of the Island. So you win some you lose some. Over all a very pleasant trip that I highly recommend…”
