Established as a national park in 1980, the Khao Sok National Park is a virgin rainforest surrounded by limestone mountain ranges and high cliffs. With an area of approximately 646 square kilometers, the main attractions in the park include Namtok Mae Yai and Namtok Sip Ed Chan which can be reached by car while other waterfalls and caves are accessible by foot.
The area is home to wildlife animals like elephants, leopard, serow, langurs, tigers and bear. Rare flowers can also be found here, but what most visitors are looking forward to see is the Bua Phut or Rafflesia kerri meyer, a flower which can only be found here and is claimed as the largest flower in the world with its diameter reaching up to 80 centimeters when in full bloom during October and December. Note that a 5-8 hour walk is required to see such flower. The park’s and other entrepreneur’s bungalows, camping area and raft-houses are available at the park.
