This is an attraction worthy of at least one full day and access to a car. Recommend staying nearby, seems too far away for a day trip tour from Chiang Mai, and for access by motorbike. In my opinion it was absolutely worth the 300 thb entry fee. If you must choose just a few attractions, I would drive to the end of the road first and visit the summit (20 minutes) and walk the Ang Ka nature trail (45 minutes). It's cold up there, so bring extra clothes. It was 12 C and very damp when I visited in mid November. Next head back downhill and walk the Kew Mae Pan nature trail (1.5 to 2 hours, you must hire a local guide for 200 thb, but absolutely worth the time and money). Then you can visit waterfalls as you continue the descent. Sirithan waterfall was dramatic, but you can't get close, you can only view from a distance. No facilities here. Wachirathan waterfall is worth stopping for. Very dramatic falls and you can park very close. Food sellers and toilets here too. Mae Klang waterfall is also nice, but in a different way. Yes it's a big drop, no you can't get too close to the main part of the falls, but you won't have as many people to fight for photo space. There are food sellers and toilets here as well. And finally, Mae Ya waterfall. I was determined to visit this place based on descriptions on the national park website, however I found it too difficult to access. Map program sent me along the tiniest roads through the tiniest villages, each turn resulting in a narrower road. Turned back with 10km to go. Know there's a better way to access this place, but my gps failed me today.

It was a very cool experience to drive all the way to the roof of Thailand. We unfortunately drove on the mountain via Highway 1192, but had to take a mandatory right turn at the National Park checkpoint and make a U turn at the Hmong market. We were very lucky with the weather which was quite clear. And cool. Very strange to experience near zero temperatures in Thailand. A must do experience if you have the chance!

The Doi Inthanon National Park does indeed merit its name as the most popular national park in Thailand. The tour we signed up for consists of visiting the region's famous waterfalls, mountain trails and a stopover at a remote Karen hilltribe village. The park is located about two hours drive from Chiang Mai. Our guide told us that the park is also known as "The Roof of Thailand" as we are literally at the highest point of the country. The park is part of the Himalayan mountain range with elevations going up 2600 metres above sea level. Perhaps it was December, so there was cool air everywhere. The temperature is similar to that of being in an air-con room, so bring a sweater with you.

Very pleasant to roam through the gardens at the Twin Pagodas and stand by the waterfalls (given good weather). Great day-trip to take in nature and enjoy mountain views. Wachirathan waterfall was magnificent and Twin Pagodas were a romantic, picturesque location to take photos and relaxedly spend 45mins-1hr. Things to note are that all these spots are open to the elements and your experience will likely be affected by rain or sun and that there is a significant amount of climbing to be done.

The day we went was very drizzly, cool, and foggy, but that is what made it great! It was a welcome reprieve from the heat and humidity in Chiang Mai! Granted, you can't see the views with fog, but it was still worth a trip. We drove into the area and had to take one of their taxis up higher. We were able to take an escalator to go to one of the pagodas (only on the way up--had to walk down).
