The Buddha Mountain or Khao Chi Chan (Thai: เขาชีจรรย์) is a limestone hill in Na Chom Thian that has become a Pattaya landmark due to its large 109 m (358 ft) by 70 m (230 ft) golden Buddha laser engraving. It was created in 1996 to commemorate the 50th anniversary of the coronation of His Majesty King Bhumibol Adulyadej, and for Thai people and Buddhists for spiritual practice. The Khao Chi Chan Buddha image is the largest carved Buddha image in the world.

The area surrounding the mountain is full of heavy clusters of grasses, shrubs, and trees including teak, acacia, Siamese rosewood, black rosewood, and various fruit trees such as Indian gooseberry, black plum, and ramontchi. The lush green surroundings seen in the 2020s go back to the development of the Siri Charoenwat Forest Plantation Project in 1990, named after Queen Sirikit, which was initiated by His Majesty King Bhumibol Adulyadej in 1992 on the occasion of Sirikit's 60th birthday.

The Buddha Mountain together with the nearby Buddhist monastery Wat Yansangwararam Woramahawihan, the royal Chinese temple Viharn Sien, the Nong Nooch Tropical Garden, Silverlake Vineyard and the National Park form a large tourist attraction near Na Chom Thian, Jomtien and Pattaya.

The Buddha Mountain is a popular place for leisure activities, mediation, celebrations, and dance performances. As of 2016, Thai, Chinese and Russian tourists made up the majority of visitors to the area. According to the Forest Training Department, around 1,000 monkeys were living around the mountain in 2015.
