This will be a 9.4 km, there and back hike. From the Chiang Mai Railway station we will travel 56.4km out to near the border of Chiang Rai and Chiang Mai provinces along route 108. We will drive right up to the peak of Radar Mountain which is 1386 m above sea level and walk from there to an unnamed peak at 1667m above sea level in 2.26km then another 2.29km back down the ridge on the over side and on to Doi Pa Ngom which is 1724m above sea level. Following this path along the Chiang Mai and Chiang Rai provincial border will be one of the groups most challenging hikes. It will be very steep at times with some dangerous sections where the trail gets so steep we must be very careful. It will involve a lot of work to ascend and descend the peaks. The scenery over on this side of town is fantastic though!

Comparison of this Trail With Other Trails We Do

In total, over the 9.4km there and back trip, we will be climbing 930m (634m on the way out and 296m on the way back) and descending 930m (296m on the way out and 634m on the way back). Compare the trail one way with that of other hikes we do often :

  • The trail one way on this trip – 634 m altitude gain over 4.69 km. Max slope 54.6 %, average slope 20.3 %.
  • The trail up to Doi Langka Noi – 598 m altitude gain over 3.15 km. Max slope 48.5 %, average slope 21 %.
  • The trail up the back of the peak of Doi Pui – 340 m altitude gain over 1.64 km. Max slope 35.7 %, average slope 20.5 %.
  • The Palaad Trail from the start of the Palaad Nature Trail (which is near the radio antenna) to Wat Palaad – 278 m altitude gain over 2.4 km. Max slope 26.3 %, average slope 12.8 %.
  • Start of the Galare Loop up from the Galare Restaurant to the sala on the road to Doi Suthep where there is a view point, and some times a coffee van – 342 m altitude gain over 2.14 km. Max slope 33.3%, average slope 16.9%.
  • Start of the Chiang Kian Waterfall Loop – 223 m altitude gain over 2.01 km. Max slope 27.8 %, average slope 11.3%.

Finding the way to the trail head and up to the first unnamed peak

Up to the second peak Doi Pa Ngom / Doi Mae Tho

The second peak on the trail it seems has two names. The military map marks it as Doi Mae Tho but the sign on top says Doi Pa Ngom.

GPS Trail

Attached is the GPX and Google Earth KML trail showing our track across the mountain range on our 2 day exploratory trip. We will only be covering the first 4.69 km of this trail from the first peak.

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

Chiang Mai Railway Sation Main Entrance

Chiang Mai Railway Sation Main Entrance

This time we will meet at 8 a.m sharp at the main entrance of Chiang Mai Railway Station (pictured above).

  • Head out to Nawarat Bridge.
  • Cross the birdge and keep going out on Charoen Mueang Rd.
  • The Railway Station is on the right after 1.9 km.
  • Enter the railway station and meet us at the main entrance to the station itself. It is better to park outside as there is a charge for parking after 20 minutes in the car park.

Transportation from the meeting point

We will share cars to drive out to Radar Mountain. It is 56.4km from the Railway Station and will take a little more 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. 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 56.4km journey, if sharing a car. If we need to rent a songtaew the shared cost may be a little more.


  • Bring around 2-3 liters of water or more, some kind of lunch and snacks
  • Good footwear etc. hat, mozzie repellant and sunblock

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.
