One of the insider tips of the Phang Nga National Park: Koh Hong Island, which has not yet been discovered by mass tourism. Hong means "space" in Thai, and you quickly learn why the island is so called: Every day - in a period of just half an hour - you can swim or wade through a narrow gap in the rock and arrive at a grotto surrounded by cliffs, which is open at the top. A very exotic room... A dreamy beach in the midst of this unreal environment is just waiting guest which like to enjoy the exclusive envoirement.
The entry to this area is 300 THB / Adult, which have to be paid cash to the Park Rangers. There are different rates for Thai nationals, foreigners, adults and kids.
Please note: In some areas additional park fees have to be payed cash to the Park Ranger. Due to the double pricing system it might be different for nationals and non-nationals.
