This will be a short sedately paced hike on level ground beside a river, there may be some clambering over rocks though.

Ob Khan in Feb 2009

So far as I can see 15 persons joined this walk on 24th January 2010. My own record of an earlier walk on 14 December 2008 tells me that we did 5 kms there and back; other data is lost in the depths of my human memory. As the water level in the river here, Mae Nam Khan, is fairly low the first half of the walk will be on the shore. There may be some tricky steps due to debris left during the rainy season, but mainly it is not a difficult walk. The return will be along the path on a slope which offers a little bit more of ups and downs.
We shall follow the Ob Khan Nature Trail which is a ‘there and back’ walk along the valley and gorge with some sections not shaded, partly through forest, by a river. It is very picturesque.

It is a nice walk on a nice day (something I cannot promise) with a possibility to get a closer look at all the rock formations created by the river. My description is based on the reports of the walk of 24 Jan 2010 and on an exploration of 19 Dec 2010. However, on last year’s walk we were able to venture further up stream by about a half kilometre. On my recent exploration I could not find the track for that extension so we are likely to walk only 4 kms unless we all decide to go a bit higher and walk up the hill to some disused facilities.
Although we may stop for a “water” break up stream the plan is to take lunch at the restaurant at the end of the walk.

The hike leader for this hike is Brian.

If you want to join

Just turn up at the meeting place on the day. There is no need to let us know you are coming unless you are coming in a big group.

Meeting Place

This time we will meet at 8 a.m in the car park of the Huay Kaeow Arboretum (also known as the exercise park).

  • Head straight out from the moat 3.5 km towards Doi Suthep on Huay Kaeow Road.
  • The arboretum is on the left after the front entrance to Chiang Mai University and just before the entrance to the Zoo.
  • The car park of the arboretum is at the end of the park near the zoo.

See the maps below (click to enlarge them).


  • Bring around 1.5-2 liters of water or more and snacks
  • Good footwear etc. hat, mozzie repellant, sunblock and rain gear

If by chance it is raining heavily we will probably cancel the hike. But in the case of lighter rain if it looks like the weather might clear up we will probably go ahead with the hike and brave the rain which will at least cool us down.
