Phi Ta Khon or Pee Ta Khon (the Ghost Festival) is the name for a festival held annually in Dan Sai, Northeast Thailand. The events take place over three days some time between March and July, the dates being selected annually by the town??? mediums.

The Ghost Festival is also called Wan Ruam (assembly day). The town??? residents invite protection from Phra U-pakut, the spirit of the Mun River. They then hold a series of games and take part in a procession wearing masks made of rice husks or coconut leaves with hats made from rice steamers, plus patchwork clothing. They also wear bells and wave wooden phalluses.

The province is covered with low mountains, while the capital Loei is located in a fertile basin. The Loei River, which flows through the province, is a tributary of the Mekong which, together with the smaller Hueang River, forms the northern boundary of the province with neighboring Laos.

Although temperatures in the hot season (April-May) can be more than 40 degrees Celsius, the province is the only one in Thailand where temperatures regularly drops below freezing at night in the cold season (December-January).

Loei is rich in national parks, including especially Phu Kradung, Phu Ruea, Phu Suan Sai (also known as Na Haeo) and Phu Luang Wildlife Sanctuary.
