Phuphayon National Park

Phuphayon National Park sits on the Phu Phan mountain range in the Tao Ngoi zone near Sakon Nakhon city center. The access road has moderate gradients suitable for regular vehicles. The park is known for its purple Dusita flower fields that bloom from August through January, though some areas fall within patrol zones and require permission from staff before visiting. Certified as a Dark Sky Park, the site offers excellent stargazing opportunities. The recommended viewing point is the dam at Huai Huad reservoir, where visitors can observe stars in all directions, the Milky Way, and meteor showers including the Geminids in December. The park provides shaded camping areas with restroom and washing facilities, while accommodation can be reserved through the national park booking system. Kham Nam Sang waterfall is located nearby. Visitors should plan trips during waning or crescent moon phases, bring warm clothing, pack out all waste, maintain quiet after 10pm, and use lights responsibly without spotlights to preserve the dark sky environment. Rates range from 30 to 950 baht per person per night, and equipment rental is available.
