Doi Inthanon

Doi Inthanon, or Mountain Inthanon, is the tallest mountain (2565 meters high) in Thailand, located in northern Thailand, about 1 hour drive away southwest to Chiang Mai. Inthanon refers to the last King of Chiang Mai.

Summit

The mountain has many type of forests, near the summit, the cloud rainforest, lower elevations pine forest and mixed forest. The summit of Doi Inthanon is relative flat and covered by rainforest; from the summit, we can not see surrounding mountains, even not the lower slopes of the mountain. There is a short boardwalk trail through the rainforest around the summit area and a small monument - King Inthawichayanon's Stupa.

We got to the summit around 9:30 am. It was cool, 10C, the surroundings were clear of smoke and the sky was blue above our head. Sunlight shone through the dense forest, bird chirped all around, it was a great time to be there.

Kew Mae Pan Trail

Many trails are short, but there are a handful long trails. We picked Kew Mae Pan nature trail, the acclaimed most beautiful trail in Thailand, its trailhead is about 400 meters lower than the summit elevation. The trail is a ~ 2 mile long loop, with an elevation change of 138 meters, portion of it is pretty steep. 

The first  mile ascends to the Kew Mae Pan viewpoint, the highest point of the trail,  it passes through a cloud rainforest, with crossing with a creek and a small water fall. Before reaching the viewpoint, the last 100 meter or so of the first mile is in an open meadow.  The grasses in the meadow were brownish due to the dry hot season, but still lively, they swayed in the breeze with chirping birds flying over.

The viewpoint has a panorama view of the area west to Doi Inthanon. Unfortunately we could not see far due to smoke at lower elevation. The middle 1/3 of the trail, is on the west facing slope of Doi Inthanon, the trail is narrow, and descending. There is a big rock seemingly out of place with its surroundings. White and Red wild flowers dotted the trail, and slopes. 

A short detour allowed us to see the twin pagodas -  Pagoda Noppamethanedon & Pagoda Nopphonphusiri.

The chorus of birds accompanied us almost all the time, which made the hike so much more pleasant.

Water Falls

Doi Inthanon has many waterfalls at lower elevations, we went to 4 of them. The most famous of them all is the Mae Klang waterfall. This is a beautiful waterfall, with two cascading falls. There is also a trail by the canyon. We hiked on the trail, and got close to the upper fall. 

Interestingly there was nobody there except us at the waterfall. It turned out that local vacationers actually rented shelters by the creek downstream, they enjoyed the water in the shade of shelters under trees along the creek, while kids were playing in the stream.

Another desolated water fall is Siriphum waterfall, again we were the only people there at the waterfall. We could view the waterfall much better on the road to the waterfall than at the official viewpoint of the waterfalls. There is a beautiful tropical garden at the official viewpoint of the waterfall, but we could not see the waterfall itself from there due to dense vegetations. We found a trail going uphill, and through it we hiked to the bottom of the second waterfall cascade. 

Strangely we saw many hoses on the ground and across the creek. Were they used to divert the water from the water falls? Were they used to pump water to the top of waterfall to make water running during dry season? It seemed to be former.

The other less visited waterfall is Sirithan Waterfall. The reason for less visitation was due to the closure of waterfall viewing platform for repair. We hiked down 40 meters from where the platform is. The unofficial trail was very steep, 70 degree slope. The hiking was treacherous, but the views and tranquility at the bottom of the waterfall made it worthwhile.

The most visited waterfall was Wachirathan Waterfall. In addition strong water flow there, another reason for the high number of visitors was that the parking lot is only 30 meters away from the waterfall. There is a trail starting from the bottom of the waterfall, and going downstream 100 meter or so where the trail is blocked due to safety concerns. This is a beautiful waterfall, with good amenities. We had an ice cream break after the short hike.

We enjoyed visiting and hiking at Doi Inthanon. 

A season without smoke and heat should have made it 100 times better.

Notes

1. Doi Inthanon national park has fees for entrance

2. Kew Mae Pan Nature trail requires hiring of local guide (200 Bhats) for each visiting group - this helps igneous people economically and let them get the benefits of conservation.
