North part of route is through valley of tourist traps, tiger kingdom, insect zoo, ATVs, bungee, monkey show, orchid garden, snake farm, elephant stay...waterfalls. After waterfalls nice part of route begins. Good surface, corners, nice landscape. You can stop at Samoeng. There are some tribes, you can maybe visit there
Sources for me going there were.
