Around 2016-17 I had the opportunity to go to Dorokha from Samtse but I didn't go as people said it too remote and there is not there. But watching your video and seeing the beautiful paddy field made me to regret it. I have been to sombaykha from Haa via tergola. The bridge was incomplete with road that can be ridden only by 4WD. It's good to see the road is blacktopped and people are well connected. Ride safe and keep traveling. Life is for the living!
