Thai National Observatory

The Thai National Observatory is a research facility on Doi Inthanon Mountain, equipped with a large reflecting telescope for astronomical observations. The station includes information displays, researcher accommodations, and sits within a national park at high elevation.

The research facility was established in 2013 to advance astronomical research in Southeast Asia. The project marks a turning point for scientific development and international cooperation in the region.

The observatory represents Thailand's commitment to astronomy and science education in the region. Visitors experience a window into international research and how the country develops its scientific community.

Visitors reach the facility through Doi Inthanon National Park and should be prepared for thin air at this elevation. An information station at the entrance helps guests understand the site and plan the best time for viewing.

The facility houses Southeast Asia's largest optical telescope with a primary mirror manufactured in Russia and assembled in Arizona. This international manufacturing process shows the global cooperation behind this scientific resource.
