We start from our pier to Ko Tachai by speedboat. Arriving at the island you have time to enjoy the feeling of the finest sandy beach under your feet and to explore the island step by step. If you wish, we take you with us into the jungle to search for chicken crabs, lizards and other wildlife.

And if you fell in love with the dreamlike landscape at first side you maybe might want to stay there a little longer. This is absolutely fine for us – we will pick you up later, no worries.

Everyone else can join us on the boat to head off to our first snorkel stop. A colourful underwater world with lovely coral reefs and hundreds of fish – big and small – will make it easy to enjoy your time in the warm but still refreshing water. At about one hour later we will return to the beach to take some tasty Thai lunch together.

And then it is time to seek for another beautiful snorkel spot, to look for the most beautiful fish, sea stars and corals. After a long and exciting day we will head back to the pier and to your hotel. For you it means time to relax, as our drivers will take good care of you.
