To/From Doi Inthanon
Transport for Doi Inthanon leaves from the car park in front of Wat Prathat Si Chom Thong, costing 140 baht per person by songthaew or 180 baht per person by minibus.
You can alternatively hire a whole pick-up or minibus for 1,500 or 1,800 baht respectively. These will take you to the summit of Inthanon with stops at Wachiratarn Waterfall, a hilltribe market and twin chedis on the way. Entry fees are not included in transport costs. Departure times are whenever the bus is full so on quiet days you could be waiting a while!
There is no other public transport for Inthanon, though Mae Chaem-bound songthaews will drop you at the ticket booth. Songthaews also depart from Chom Thong’s central square in front of the wat for other local destinations like Chiang Mai, Sanpatong, Mae Chaem and Hot.
To/From Mae Chaem
Irregular songthaews for Chom Thong depart throughout the day from in front of the school past the Kasikorn bank on Inthanon Road in Mae Chaem. Fare is 70 baht per person for a two-hour or so drive. That’s it -- no public transport is available for Khun Yuam from here.
If you’re travelling by motorbike, Khun Yuam’s more than 100 kilometres of ups and downs and corners and hairpins away, with a few villages en route for refreshments and petrol. It is of course scenic and the road’s in pretty good condition.
Heading south it’s approximately 45 kilometres to the junction with Route 108, where a left turn takes you past Ob Luang National Park into Hot, or a right turn leads off to Mae Sariang. This follows the Mae Chaem valley for stretches and isn’t quite so hilly.
Another precipitous ride however takes you over forested hills to the Chom Thong, Inthanon Road and national park checkpoint some 24 kilometres distant. Here a left turn takes you up the mountain itself while a right leads 40 kilometres or so down a spectacular valley to Chom Thong and the main Chiang Mai highway.
