This will be a very grueling hike about 15km in length. We must keep up a brisk pace with only short stops for refreshments. A good level of physical fitness is required & hikers must be comfortable following narrow rocky trails with steep drop-offs. In places the track is not easy to find & we will be walking across rocky forest floors until we relocate it. Good boots with ankle support recommended. About halfway round the hike, we ascend a very steep rocky scramble to the highest peak at about 1000m. If it is too hot at this stage, we can decide whether to continue the walk along the ridge or drop down through the forest to the dry stream bed & back to the start point.

We will drive about 30km from CM Railway Station & park at the east end of the southernmost dam at the Huay Lan Royal Project. A short level walk along a dirt road will bring us to the start of a steep climb of 400m following a pilgrim’s trail up to a shrine & stupa on top of a cliff overlooking the Chiang Mai valley. This path has steps cut into the hill in places & steel step ladders to climb up a gap in the cliffs. After a short break we will continue the hike along the ridge. The path follows a series of peaks around the rim of the watershed. We will eventually drop down to another reservoir & then walk back 1km along a road to our starting point. I did this circuit a week ago, took 3 litres of water. It wasn’t enough. Recommend 4 litres. And lunch & snacks.

Transportation from the meeting point

We will share cars to drive out to On Tai. It is 30 km from the Railway Station and will take a little less than one hour to drive out there. For those who do not have a car there are normally just enough spaces in cars to fit everybody in. We do this all the time and there have always been enough spare places. If there are not we can arrange transportation by songtaew. We would suggest a 150 B donation towards petrol for a lift there and back for the 30 km journey, if sharing a car.


  • Bring around 4 liters of water or more, some kind of lunch and snacks
  • Good footwear etc. hat, mozzie repellant and sunblock
