Doi Sa Ngo is a mountain peak in Chiang Rai. It is a beautiful eco-tourism destination and ideal for nature lovers. What makes it a unique place is that from its summit you can see Thailand, Myanmar and Laos all from one great point; It is called the Golden Triangle, and here you are surrounded by natural beauty on all sides, and if you come at the right time (in the early morning hours), you can even see an unparalleled view of a sea of clouds.
