    Crystal clear water, soft sand, nice island vibes. This was one of the highlights of our trip to Thailand. Loved every stop, especially snorkeling near the coral (the cave was less interesting). Our guide was funny and made the day fun.

    Super expérience ! Très bien organisée, les guides sont très sympathiques, attentifs et serviables. Et évidemment le cadre est splendide. L’expérience snorkelling est top : nombreux et superbes poissons. Et le déjeuner du midi est vraiment très bon. Le timing est très bien équilibré sur la totalité de la journée.Nous recommandons vivement.

    Super day of snorkelling at Koh Rok and Koh Haa. Beautiful clear water with abundant fish. Koh Haa beach is picture postcard. Helpful team from pick up, boarding, lunch offering and taking back to hotel. A professional company who know their stuff.

  • Cameron Johnson

    Truly a great experience! Time at the market to learn about the products that we would require for the dishes being presented. Then a fun but educational class of preparing Family Thai dishes.

  • Ma T

    Fantastic longboat tour of 4 islands around Koh Lanta. The tour guides were excellent and explained everything along the way very well. Overall a great experience and would recommend.

  • Mephisto Pheles

    We had a great time with Non and his team. The trip was smooth and well organised. You have ample time to enjoy each location. Value for money. The food was delicious.
