The park is 12 kms. from town and covers an area of 400 square kilometres. It mainly consists of a mass of limestone islands, rock formations and evergreen mangroves. Boats are available at some landings near the park office to explore a number of interesting islands. These include:
Khao Khien This mountain cave, which contains primitive rock paintings of various animals such as fish, water lizards and dolphin, is believed to be some 3,000 years old.
Ko Panyi Around this island, there is an entire Muslim fishing village of about 500 households built on stilts on stilts in the sea and connected by wooden bridges.
Ko Thalu This island with a big cave eroded by sea water offers a spectacular scene of enormous stalactites when boat trips are made through the water-filled cave.
Khao Phing Kan This gigantic cliff appears to be cloven in two ; the halves supported by leaning against each other offers a sight of rare and exquisite beauty.
Khao Tapu This spectacular tall island stands in front of Khao Phing Kan. Its broad peak and narrow base gives the strange appearance of a spike driven into the sea.
Tham Lot Similar in appearance but larger than the cave at Ko Thalu, this cave is about 100 metres long and a small boat may pass through it.
Khao Machu Here on a hilltop, there is a rock formation resembling a dog.
Ko Yao It takes 2 hours by boat from Phangnga or 1 1/2 hours from Ao Po, Phuket. Ko Yao covers an area of 137 square kilometres consisting of two main islands: Ko Yao Noi and Ko Yao Yai. There are several beaches on the islands including Hat Pa Sai, Hat Tha Khao, Hat Ao Tikut, Hat Khlong Son and Hat Loparaet. Bungalows are available.
