Op Luang National ParkAbout Op Luang National Park
Op Luang National Park is a protected area in northern Thailand known for a deep river-carved gorge, waterfalls and archaeological cave sites. The park preserves steep-sided rock formations and river scenery rather than developed tourist facilities.
The primary highlight is the Op Luang Canyon, a narrow gorge carved by the Mae Chaem or Mae Wang river with cliffs that reach tens of meters in height, plus riverside trails and viewpoints. The park also contains waterfalls and caves with prehistoric archaeological finds.
Archaeological surveys in the area have recorded prehistoric artefacts and rock paintings in caves and rock shelters, indicating long-term human use of parts of the canyon and surrounding landscape. The site has been managed for conservation and low-intensity tourism.
The park is located in northern Thailand’s mountainous region, within Chiang Mai Province, southwest of the city of Chiang Mai. It is reached by road from nearby district centers and sits in a forested river valley landscape.
- Viewing tip: Best views of the main gorge are often reached via short trails from the park entrance, and the canyon is most photogenic in late dry season when river levels are lower.
Best Time to Visit Op Luang National Park

Tips for Visiting Op Luang National Park
- Arrive early to see the marble cliffs and the waterfall before crowds and mid-day haze.
- Wear sturdy shoes; the trail into the gorge has steep, sometimes slippery sections and a few ladders.
- Bring a refillable water bottle - there are no reliable shops inside the park, and the remoteness makes resupply difficult.
