History
The Bronze Drum of Dongson Culture (500BC - 100BC) that was found on Ko Samui in 1977 is evidence that there were settlements of people on Ko Samui, Ko Pha Ngan, and their islets from more than two thousand years ago. Some historians and archaeologists believe that the first group who migrated to Ko Pha Ngan were the Muslim sea Gypsies (Pygmy, Semung, and Proto-Malay) who travelled by boat from the Malay Peninsula. However, nowadays there are few Muslims who live on the island. The name of Ko Pha Ngan comes from the word 'Ngan', the southern dialect meaning 'sand bar', for there are many sand bars offshore around the island.
Administration
Ko Pha Ngan together with Ko Tao forms the district (amphoe) Ko Pha Ngan. The district is subdivided into three subdistricts (tambon):
Originally the island was administrated from Ko Samui district. The minor district (King Amphoe) Ko Pha Ngan was established on October 1 1970, then consisting of the two tambon Ko Pha Ngan and Ban Tai. [1]. It was upgraded to a full district on April 12 1977.
Parts of the tambon Ko Pha Ngan and Ban Tai form the township (thesaban tambon) Ko Pha Ngan. There are further three Tambon administrative organizations (TAO).
Attractions
As a natural paradise island in the Southern Gulf of Thailand, Ko Pha Ngan serves as the perfect getaway retreat, where one may go relaxing on the many quiet deserted beaches including the beautiful Chalok lam Bay, Ban Tai, Ban Khai, Haad Yao, Haad Salat, Haad Son and the Mae Haed beaches. There are many activities in which to participate including snorkeling and learning to dive at the distinctive island of Ko Ma, trekking in the footsteps of Thai Royalty at Than Sadet National Park steeped in history and culture, or seeking adventure in the nearby Ang Thong archipelago composed of over 40 islands endowed with pristine beaches, natural caves and the tranquil Tha Laem Nai. Ko Pha Ngan has over 250 resorts to choose from, ranging from the budget 80 baht a night beach hut without private toilet to luxury air-conditioned accommodation with private swimming pool.
It's the simple beach life which continues to attract visitors each year along with the island's reputation for full moon parties and a hedonistic approach to life. The backpackers, budget tourists and aging hippies are beginning to give way to families and more mainstream tourists as all the beaches are fully developed.

The full moon party consists of tens of thousands in high season - all on the beach. Revelers from all over the world still flock to the world's biggest beach party every month. The music from the multiple sound systems is made up mostly of electronic styles such as Psytrance, house, techno and drum & bass and a predominantly youthful crowd dance 'til dawn on party nights. It has been reported that western tourists have been victims of unprovoked assaults by gangs on a number of occasions, particularly around the time of the full moon parties late at night in the vicinity of bars in Haad Rin. Other events such as the Half Moon Party and Black Moon Party also attract large crowds. Despite the special titles the events on the beach are identical every single night. However, it is still possible to visit the island and avoid the full moon party altogether, with dozens of quiet, secluded resorts and beach huts dotted all over the island for a variety of prices. Many of the more costly resorts offer such facilities as daily yoga, yoga teachers' training, meditation, a variety of healing, healthy & natural therapies, spa massage & pampering services and herbal steam rooms.
