DoiInthanon has a cool climate all year-round. The Air Force Radar Station and King Inthawichayanon’s Stupa are located on the mountaintop. King Inthawichayanon, the last king of Chiang Mai, was concerned about the importance of forests and wanted to preserve the forests for future generations. He was so familiar with DoiInthanon that he asked that part of his ashes be kept here.
This short trail, winding through pristine forest for about 2.5 km., a 3-hour walk, allows the hiker to experience the natural beauty of the forest first hand. The Rhododendrons, commonly found in the Himalayas, are found along the trail and they are in full bloom during December-February.
Trekkers on this route should seek permission from the Park headquarters at km. 31 for safety reasons. A group of not more than 15 people is recommended. Food consumption is not allowed while trekking. This nature trail is closed for reforestation from June 1 to October 30 annually.
The Inthanon Bird Watching Information Centre (Uncle Daeng’s Shop) is located at km. 31. This is a bird information exchange centre among bird watchers, nature students, and the general public. The information details the habitat and food of birds and animals living on DoiInthanon. The aim is to pass on this knowledge to future generations. It also provides the DoiInthanon Bird Watching Diary, bird sketches by various bird-watching experts, bird-watching trails, bird pictures, and slides.
Winter is the best time for bird watching when indigenous and migrant birds are found including the Eurasian Woodcock, White Wagtail, Grey Wagtail, Yellow Wagtail, Citrine Wagtail, Forest Wagtail, Chestnut Thrush, Scarlet Finch, Little Bunting, and Crested Bunting.
