There is a Tourist Information Center about 9 kilometers along Route 1009, which leaves the Chiang Mai - Hod Highway just before Chom Thong's town center and heads over Doi Inthanon to Mae Chaem. Just one kilometer or so past the entrance the Information Center is on the left. personally. Many exhibits and a slide show in English about the park are on display. There are also stiff fines for those who break park rules (such as picking flowers) that need to be known. The park rules are written on the back of the map and brochures.
In the Angkga - Inthanon mountain range, close to the Mae Glang waterfall, is the huge Borijinda Cave. To reach the cave, turn right off the Chiang Mai - Hod route at km. 58, on the road to the waterfall. After 8 kilometers turn right and keep going 1 kilometer toward Doi Inthanon. There one will find a sign pointing to the cave. Before the cave, there is a sign with the history of the cave's discovery. Many kilometers deep, the cave has many beautiful stalactites and stalagmites, appropriately called Nom Pha, or milk of the cliff, in the northern Thai language.
There is a Buddha image in the cave, and an underground stream of such purity that light sparkles from the surface like a million diamonds. The roof has collapsed in places and much of the cave is flooded with sunlight. When exploring, be sure to bring your own flashlight with extra batteries.
The Wachiratharn Waterfall is a large cascade which plummets over the edge of a high cliff into a deep pool below. Opposite the fall is a tall and precipitous cliff called Pha Mon Kaew or, more lyrically, Pha Gorn Kaew. The waterfall, some 750 meters above sea level, which was formerly called Tad Kong Yong, is an excellent picnic spot. To get there, turn right off the main road up Doi Inthanon at about 21 kilometers, then follow the signpost to the waterfall a further 350 meters on foot. At km 20 a new road is under construction to reduce the walk to the waterfalls.
The Doi Inthanon Park Headquarters is located at km 31,
Beside the main road over Doi Inthanon is the Royal Project Station in Baan Khun Klang (Glang), quite close to the National Park Office. This project was initiated in 1979 as part of His Majesty the King's efforts to help the hilltribes to cultivate cash crops other than opium, to introduce them to modern agricultural practices and to help them protect forests and river catchments.
This particular station has responsibility for research into temperate. Zone plant species as well as providing agricultural advice and support for 510 neighborhood Karen and Hmong families.
Between km. 41 and 42 are two fine opportunities for experiencing nature along the whole of the road over Doi Inthanon. At about the 41 km marker is one of the finest views to be had from Thailand's highest peak. A short walk of about 30 meters from the left side of the road gives the viewer a chance to see a sea of mist filling the valley below. A little further on, at about km 42, is the nature trail called Gew Mae Paan. This short trail, winding through tall pristine forest for about 2.5 kilometers, a 3-hour walk, allows the hiker to experience the natural beauty of the forest at first hand.
This is where to see warblers and kingfishers as they feed on insects in the bushes. Travelers wishing to use this path should seek permission from the National Park Office at km. 31, not only for their own safety, but also to ensure that no damage is caused to the precious environment.
NOTE: Every year from June 1 to October 31 the area is closed to the public.
For a truly splendid view from Doi Inthanon, as well as gaining insight into the reverence of the Thai people for their Royal Family, visit the twin pagodas Phra Mahathart Napametaneedon and Phra Mahathart Napapol Poomisiri. These beautiful structures were built by the Royal Thai Air Force and the people of Thailand to commemorate the 5th cycle birthdays (one cycle being 12 years) of Their Majesties the King and Queen The first of these pa godas, erected on the occasion of The King's 60th birthday in 1987, is 50 meters wide and 60 meters tall. Inside a Buddha relic and an image of the Buddha is housed.
