The Sirinath National Marine Park is an exceptionally large ocean park. With Phuket International Airport to the west and the city of Phuket to the north, the park encompasses the four beaches of Nai Thon, Nai Yang, Mai Kao and Sai Kao. This area is especially precious as, every year, a large number of leatherback sea turtles come here to lay eggs. This is one of the best places in Phuket to see all kinds of unique flora and fauna. While here, visitors can appreciate the special ecological environment of the saltwater marshlands.
