Pang Ung, officially known as the Pang Tong 2 Royal Project (Pang Ung), is a large reservoir on a high mountain peak, surrounded by magnificent pine forests, earning it the nickname "Switzerland of Thailand." It is one of Mae Hong Son province's most popular tourist destinations, attracting visitors to experience its natural beauty, especially during the winter.

This place has a long history. Originally, the area was used for shifting cultivation by hill tribes, leading to deforestation. Later, His Majesty King Bhumibol Adulyadej The Great (Rama IX) initiated a royal project to restore the forest and build the reservoir to improve the livelihood of the locals and conserve natural resources.

It was further developed to preserve the cultural values and faith of the community. Her Majesty Queen Sirikit, the Queen Mother, graciously gifted a pair of white swans and a pair of black swans, which were released into the reservoir, adding a lively and memorable charm to Pang Ung.

During special seasons, particularly the cool winter from October to February, the scenery is at its most beautiful. Visitors can witness the enchanting sight of mist hovering over the water's surface in the early morning, contrasted with the golden rays of the rising sun, creating a truly romantic and impressive scene.

This location is also perfect for photography lovers and outdoor enthusiasts. Popular activities include camping under the pine trees, taking a bamboo raft to enjoy the reservoir's scenery, or simply strolling around the project to appreciate nature.

If you wish to experience a blend of natural beauty and the inspiring story of a royal project, a visit to Pang Ung is an unmissable part of any trip to Mae Hong Son.
