Reviews: Thailand Ko Rok + Ko Haa 1-day tour|Island hopping + snorkeling|Optional departure from Phuket, Krabi, or Lanta
Guest User2026-10-06
Krabi's Koh Loc and Koh Ha island hopping day trip was fantastic! Hotel pick-up was very punctual, and the driver was waiting at the resort entrance early. The boat guide and instructor were very friendly, spoke Chinese, and patiently guided us throughout the snorkeling session; the underwater corals and fish were especially beautiful. The seawater on both islands was a beautiful turquoise blue, and the beaches were fine and clean. The itinerary was well-paced and the equipment was complete; life jackets and snorkeling masks were all clean. Overall, it was a very hassle-free experience, highly recommended!

The trip was a bit tiring, with long drive and boat rides. There weren't many fish at the dive sites, and visibility was average.

Reviews: Mangrove Tour by Kayaking in Ko Lanta With Lunch
Guest User2026-05-16
We went on this activity in May, and it was amazing! ​We received a WhatsApp message the day before to organize the transport. The driver arrived the next day right on time, which was perfect. Then, our guide Ramadon welcomed us. He is a very pleasant young man with good English. ​We set off to explore the mangroves. Our guide was very attentive, highly knowledgeable about the area, and made the whole tour incredibly enjoyable. We were able to see a snake, monkeys, hawks, crabs, and snails. Since it was the low season, we were lucky enough to be the only ones with the guide. I highly recommend doing this kind of activity during this period. ​The activity isn't particularly physical, as the current carries you most of the time. We had to paddle against the current for a short while, but it wasn't very difficult. ​The food was very good and served quickly. ​I highly recommend this activity; the staff is lovely. Just remember to bring sunscreen and a hat for the sun!
