On the motorbike making a detour to Phu An Ma in Chiang Kham

While making a motorbike trip from Pua to Doi Chang I took route 1148 from Tha Wang Pha to Chiang Kham. But I made a little detour via route 4029 that goes to route 1345. At the place where route 4029 enters route 1345 you can go to the left to Chiang Kham or to the right to a small village. I did the latter as a few km before that small village is a road going to Phu An Ma. This is a mountain with a viewpoint at said to be 1.658m above sea-level. Route 1345 to that small road is already at some points very steep and has very sharp curves..... is there a road after the curve? Here in Thailand you never know!  All along the road are good signs for Phu An Ma, except at the last place where you have to take a right to the Phu An Ma. Luckily I saw it and stopped. Now that last 300m to Phu An Ma looks like an abandoned road, about 4 meter width and partly overgrown. And very steep and with a sharp curve. I was not sure if that road was in good conditioning and if there would be a place to make a u-turn at the end ..... so I did walk instead of riding. But in hindsight I could have ride up as the road is good and there is a huge parking. At the parking is a 200m steep walking trail to the summit. Following are a few photos.
