We'll pick you up from your hotel in Chiang Mai and transfer to the base of the climb in Chom Tong. The duration of the drive is approximately 1 hour. An early start (around 6:00 am) is recommended to make the most of the riding in the cool morning temperatures.

DOI INTHANON RIDE | 45 km | 2,500 m

We start cycling in Chom Tong, barely 45 km from the top. The initial 7 kilometers are a good warm up as the only flat section on this ride.

Then we'll need to cross the entrance gate to the National Park (the THB 300 fee is not included), and we'll start the climbing.

After almost 20 km we'll encounter the gorgeous Wachirathan waterfall, where we can take a break to enjoy some snacks and drinks, or we can keep going if you want to set a PR time on the climb!

The last 9 km of the Inthanon climb feature a demanding average gradient of 9%, when you already have 1500 meters of climbing in your legs! Some ramps up to 25% will surely take away all the energy left in you.

At 2200 m above sea level, we will leave the iconic stupas on our left and then we’ll reach a huge viewpoint on our right. It might feel like the top of the mountain but we still need to climb over 300 meters to get to the highest point in Thailand!

You’ll feel a great deal of pride at the summit of Doi Inthanon, it's no mean achievement, so a photograph at the altitude marker is in order. If you ride between October and January you might need a jacket since it’s likely that the temperature goes below 10 degree Celsius at the top!

Enjoy a cold beer on the summit and jump on the support vehicle for a comfortable and safe descent. There is the option to ride down* but extreme caution is advised due to the steep gradients.

*MAY 2023 UPDATE: downhill by bicycle has been banned and riders in violation of this ban will be fined by the National Park officials THB1,000.


We'll drive you back to your hotel and we'll stop on the way for lunch to celebrate conquering this epic climb!
