Our Journey on the Mae Hong Son Loop continues. Leaving Mae Hong Son City, we continue on Highway 108 southwards towards Khun Yuam town where we will then turn east on Route 1263. A chance Whatsapp conversation with a friend in Thailand convinced us to detour to Doi Mae U Kho to catch a fleeting annual event; fields of sunflowers blooming and turning the mountain sides a golden hue for only 2 weeks in November. This sounded like a detour that we should not miss.
Heading south on Highway 108 out of Mae Hong Son City, we soon came upon Pha Bong Viewpoint after about a 15 minutes drive. There are many viewpoints along the Mae Hong Son Loop but Pha Bong has got to be one of the most breath taking. offering a sweeping panorama of mountains and valleys that perfectly captures the rugged beauty of northern Thailand..
After a short stop to admire the view, we continued for another 1.5 hrs to Doi Mae U Koh. Traffic this side of the loop is light with more gradual turns compared to the roads further up north, and we could make faster time while still enjoying the scenery along the way.
After reaching Khun Yuam, we tuned east on Route 1263 before taking a small road winding its way north towards Doi Mae U Koh. As we neared the sunflower fields, the scenery changed dramatically. The green forests gave way to hillsides ablaze with colour, the roadside suddenly lined with a brilliant wall of yellow blooms swaying in the breeze.
I’ve seen patches of these yellow flowers growing wild along the roadside while driving along the Mae Hong Son Loop. However, at Doi Mae U Koh, they are grown in large fields confined to a certain area. The Mexican Sunflower, known as Thung Bua Tong in Thai, is not native to Thailand and is an invasive species of plant that was introduced to Thailand decades ago. They thrived in the cool highland climate of Mae Hong Son, and over time, the spectacular seasonal bloom typically from mid November to early December, turned these hills into a celebrated winter attraction, now promoted as one of the region’s signature natural sights. What was once just a remote highland slope is now a protected area and festival site, with simple facilities, viewpoints and camping options for visitors who want to wake up right beside the fields
After spending about an hour admiring the views, we decided to leave for our next stop at Mae Chaem. We passed several home stays and campsites catering to visitors wanting to stay close to the sunflower blooms, eventually stopped at a charming glamping style cafe for lunch. This was a relaxed break with mountain air, local dishes, and a final view of the sunflower fields before heading back on the road and the long drive ahead.
Final Thoughts on Doi Mae U Kho
Most of the visitors to Doi Mae U Kho are Thai locals, with only a handful of foreign travellers making the trip. Those who do usually come with Thai friends or guides, which adds to the place’s quiet, off‑the‑radar charm. This isn’t a mass‑market attraction and it feels like a hidden gem tucked away in the mountains.
Because the sunflowers bloom only briefly, usually from mid‑November to early December, timing your visit is everything. Miss that window and you’ll find only green hills. There’s also no public transport to the site, so the only practical way to get here is by driving, either with a rental car or motorbike, making it a rewarding stop for those exploring the Mae Hong Son Loop at their own pace.
