For some snorkelling action you could take a trip in one of the typically open fishing boats that offer excursions from every beach in the region. Half and full-day excursions bring you to quiet, pristine snorkelling areas and beautiful, secluded beaches and islands.

Some of these tours are operated on a private basis and therefore guarantee a day that runs at your pace. These trips are perfect for couples, families or small groups as parts of the day can be customised to suit your needs.

Koh Chang Marine National Park offers some of the most delightful diving and snorkelling sites. The best sites are on the west and south of Chang Island where the abundance of healthy and unspoilt corals and the great diversity of fish are the main draw.

A lunch box can be arranged by the boat owner and you can really enjoy the refreshing crystal clear waters of these magnificent islands as you marvel at the marine ecology of the area.

Off the west coast of Chang Island is a small group of islands within view from Khlong Prao and Kai Bae beaches. These include Yuak Island which has a small beachfront of sand formed from decayed corals. The water is clear and shallow qualifying it a good snorkeling spot.

Next to Yuak Island are Plee and Suwan Island, both of which have rocky shores. Around the area of Suwan Island is another isle which harbours colourful corals in 6 metres depth. As it is home to to an outstanding beautiful big tree, the locals call it "Koh Rom" what means Umbrella Island.

Further down south is Man Nai Island which is directly facing the shores of Kai Bae Beach. During low tide, the water is so shallow that it is possible to walk from the island to Seaview Resort that is located south of Kai Bae Beach.

Another island called Man Nok Island looks as if it's behind Suwan Island. It is the twin island to Man Nai Island and is linked together by shallow waters with gold-coloured seaweed.
