The Full Moon Party is an all-night beach party that takes place in Haad Rin on the island of Ko Pha Ngan, Thailand on the night of every full moon.

Background
The party was originally a small affair with a small number of backpacking travellers dancing through the night of the full moon, mainly to psychedelic trance music. Originally, the music was some tapes coming from Goa'Party (India), and the first Full Moon Party was improvised at a wooden disco not far from the beach. The Full Moon Party gained fame quickly through word of mouth, and the event now draws a crowd in excess of 10,000 every full moon evening. The party carries on until the sun rises the next day. All the bars on the sunset beach of Haad Rin town stay open and play music such as drum and bass, house and reggae. The event has become a part of the itinerary of many travellers to Asia. Entry to the event is completely free. In recent years, local entrepreneurs have attempted to expand upon the event with spinoffs like the Half Moon Party and Black Moon Party.

Drinking & dancing
Thai alcohol brands such as Sang Som rum, Mekong whiskey, and Singha beer are most popular among travellers. A signature of the Full Moon Party are the buckets - mixed drinks served in small plastic pails. A bottle of alcohol (usually Sang Som rum) is poured over ice and topped up with a can of Coke and a bottle of Red Bull syrup. Several straws are then thrown in. The price in 2007 for a bucket was around 200 baht, roughly £3/$5.50.

Drugs
In the past there has been some association with illegal drug use. Although the use, possession, and/or sale of drugs is illegal under Thai law, club drugs such as ecstasy, methamphetamine, Yaa Baa, marijuana, opium, mushrooms and even over the counter diet pills have been reported. As of 2002, the Thai government has pursued a stricter defense against illegal drugs at these events. The standard bribe for possession is about 50,000 baht (£750/$1200) and foreigners do go to jail for possession. Drug use at Full Moon Parties has lessened in recent years, in part due to greater fear of being caught but also because the parties now draw attendees from a wider range of backgrounds.

Other attractions
Fire Poi - burning, fuel-soaked balls on chains - are a common sight at Full Moon Parties. Performers, both locals and tourists, whirl these balls of fire around in the air to create a spectacular visual display.

Never went to Ko Pha Ngan but then I'm not into all night drug fueled dancing.

sounds good but sorry pattaya will do me fine

Where are the photos?

ya i only was in pataya and dont know much about the partys.
are only "farangs" there or do thais party there too?=

To be honest the partys have had their day.
Ive been going to Pha Ngan every other year since 90,and have unfortunatly seen it degrade into a Island that has sold its soul to tourism.
Even staying around the back of the island is now only a stopgap,as the sealed roads are now encrouching on even the most far flung corners.
The parties themselves have degraded from 500-1000 stoned chilled out tourists into an event that attract L/B'S,Police and other such leaches from all over....not to mention the average Farang is now a 2 week package tourist from Liverpool staying in a 3 star on Samui.
I'm sorry if i seem overly synical,but Pha Ngan used to be my own little escape to heaven...this year ive decided to pull the trigger and just spend 3 weeks in Patt with a few days on Samet,rather than have the memories ive accumulated in the Gulf trodden on...Mercutio

Went there a few years ago. Didn't like it, but my mates loved it. Two hours later,I bribed one of the speedboats 300 baht to take me back to Koh Samui, otherwise had to wait until 7 a.m. to catch the slow "ferry" (fishing boat), and we didn't have any accomodation.

No accomadation?...surly it wasnt nessasary???
In recent years just fall asleep down the south end of the beach,and wait to be woken up by a courtious,EVER so appealing,invite from any one of the local Katoey's!! ....Mercutio

I went on the 24th of November and had a good time. Wish I could of spent more time on phangan but I only ferried over for the party and then back the next day.
