Doi Samer Dao is a prominent hilltop viewpoint inside Si Nan National Park in Na Noi District, Nan Province, northern Thailand. At about 888 meters elevation, it is known for panoramic views of forested mountains and the Nan River valley, sea of mist at sunrise, and clear night skies for stargazing. The site features a grassy ridge, viewpoint platforms and a designated camping area managed by the national park.

Visitors can expect an open grassy ridge with 360-degree views over forested hills and valleys, with a paved viewpoint area and wooden viewing platforms. The site is primarily a sunrise and sea-of-mist viewpoint with camping grounds on the hilltop. Facilities are basic national park style with tent pitches, rental tents, toilets and small food shops. The environment is natural and exposed with little shade, cool in the morning and evening.
