The park contains over 42 islands, which are largely limestone plateaus with tropical rainforests and deserted beaches reflected in lime stone walls. The park has a geometric design in contrast to the other islands in the area. Erosion has created a lovely shoreline and small coves, in addition to the stunning colors of Mae Ko (a beautiful beach) and Thale Nai (an emerald saltwater lake). Koh Sam Sao contains a coral reef and a huge rock arch as well as a picturesque hill with breathtaking views. In addition to the Asian long tailed monkey (langur), hair-nosed otters, Pacific reef egrets, white-bellied sea eagles, ashy drongos, tortoises, sea turtles, lizards, and pythons, there are a great deal of animals on islands. That is the source of the mackerel, a mouthwatering Thai cuisine. Snorkelling, trekking, and swimming are the top attractions in the location. It's the optimal time to get to this region is late March to October when visibility is greatest. Get a boat and venture to the 'Golden Basin' yourself.
