In 2017 I was traveling from Nan to Chiang Kham and where route 1148 crosses the small river Mae Lao a small tourist attraction has been created. There are 3 small restaurants and 2 of them also have a Coffee Shop. Along the small river are a few sala's where you can sit, relax and eat. A lovely place for a short stop. So going to Phu Chi Fa we stopped on the left side after the river and did sit at one of the sala's where we did eat. And you can buy fish-food to give to the many fish in the small river. On the way back we stopped again at the left side but before the river. Here is a small strawberry farm and a Coffee Shop.
Update 2021 : Most of the shops / restaurants are not in functioning order anymore. This could be because of COVID. There is 1 new shop with beautiful flowers.
