Mon Jing Mountain

The Mon Jing loop over Doi Nang Mo

Mon Jing Mountain is where the Mon Jing Loop climbs over Doi Nang Mo, 20–40 minutes from Baanpong Lodge. I walked it on a clear morning in March. It is a proper hike rather than a stroll, and the view from the top takes in the Mae Pha Naen Reservoir and the hills around it.

Getting to the trailhead

The usual start is the Mae Pha Naen Reservoir. From the lodge in Ontai it is 20–40 minutes by scooter or car (the lodge can arrange a scooter) on rural roads that are mostly paved, winding, and bumpier towards the end. Parking at the reservoir is free or a small donation, and there is no fee for the trail. Start at 7–8 am, while it is cool and before other walkers arrive. There is almost nothing at the trailhead, so bring what you need.

The route

The loop is 4.9–8 km depending on the route you take, with 500–600 metres of climbing to the rocky summit of Doi Nang Mo. Most of the way is under the canopy of dense forest. Steep climbs lead onto narrow ridges and some scrambling over boulders, and finally onto open rock with views all round: the reservoir below, ridges of hills behind it, and on a clear day the Chiang Mai plain.

A small golden Buddha and prayer flags mark the summit. The trail is rough and unimproved, with none of the steps and railings of the better-known viewpoints.

What I would tell anyone going

The steep sections are hard work, and the loose rock is the main hazard on the way down — wear shoes with a good grip in sound condition (another walker’s sole came off on the day I went). Carry 2–3 litres of water, snacks, sun cream, a hat and insect repellent; the humidity builds quickly once the sun is up. Take it slowly on the descent, and go with someone else if you can, because some stretches are exposed.

November to February is the best season. March was still fine in the shade, but go early. For photographs, the summit rocks frame the reservoir well, the ridge clearings give the wide shots, and the Buddha catches the late light.

Practical information

• Hours: an open trail, with no gate; walk it in daylight only.
• Cost: free, apart from a possible small parking tip at the reservoir.
• Facilities: none on the trail — no toilets or shops. There may be simple food stalls near the reservoir. Take your rubbish home with you.
• Afterwards: eat in San Kamphaeng, soak at San Kamphaeng Hot Springs, or detour to Mae Kampong village and its waterfalls.

Back at the lodge

Because the trailhead is so close, you can be back by early afternoon and spend the rest of the day by the pool.
