Si Nan National Park – Doi Samer Dao (Nan)

Doi Samer Dao is one of Thailand’s most beloved dark-sky campgrounds, perched on rolling ridges above Nan’s misty valleys. On clear midwinter nights, expect around 10–15°C, occasionally dipping a bit lower with a cold snap. The grassy campsite arcs along a gentle slope, giving most tents a star-filled sky and an easy stumble to sunrise viewpoints without a strenuous hike.

Rentals are usually available at the Doi Samer Dao visitor area, including tents, sleeping mats, and blankets. Weekends and holidays are popular, so reserve tent space through the DNP system when offered, and arrive early to secure the flattest ground. Standard park permits apply at the entrance gate. For photography, plan around new moon dates, shield your headlamp, and step away from communal lights to let your eyes fully adjust.
