Doi, Khao, Phu all mean mountain. Khao is central and southern dialect, Phu is north eastern, and Doi is northern. So these mountains have the same name. They're not too far apart - about 70km in a straight line - and I did them in the same week, so let's put them in the same thread. Starting with Doi Luang, Tak.
Doi Luang (Nam Tok Huai Mae Khai Forest Park) Tak
I did this as a dayhike on a Sunday so as I was going up there were a lot of trekkers walking down the mountain after spending the night there, I'd say 30-40, with 5 accompanying guides and a couple of porters. I think if this had been in a national park or wildlife sanctuary I might have been turned around but since it's 'just' a forest park they aren't so strict, a couple of them asked me where I was going and when I was coming back, nothing more. One of the guides was carrying a gun, not sure what he was figuring on shooting. If going independently it's perhaps better to do it on a weekday to avoid other people. If going with a guide, best to contact the forest park ahead of time or check out their facebook for more info

The roads on the final stretch are not good; dirt and gravel. That's the mountain, centre:
Trailhead is at 16°58'3.76"N 98°59'19.26"E
The first few km are fairly flat, criss-crossing a stream. There are lots of domestic cattle roaming free. They make their own tracks all over so it would be easy to get lost without a guide or GPS file. From then it's uphill with the occasional flat section. There's about 1km of elevation gain, starting from 200m elevation and topping out at 1149m. It's 8km each way. It will be a full day hike for most people so if not camping, plan to start early AM. Moderate/Hard difficulty. Not super steep, but quite long.
Here is the GPS track.
Typical patch of forest, near the bottom:
A little further up, a view of the summit. The peak to the left which looks highest is actually a lower elevation. The actual summit is that grassy knoll to the right of it:
