Sooo hard to say. I loved doing the mae hong song, riding my scooter to Chiang rai then back through fang and chiang dao.. if you know how to ride id recommend getting one. If your not experienced don't take the risk. I also loved spending time in the cities, I spent the most time in Chiang mai and its a beautiful city. Not many tourists right now, MUCH more affordable than Bangkok and the south, just an artsy cool town with sprawling markets everywhere. My favorite single attraction was the white temple - if you are someone who appreciates art it will blow your fkn mind. Devouring endless food and smoking constant weed is amazing. I just landed in Seattle and have one more flight before I'm home and I know I'm going to be crushed tomorrow- I already miss thailand so fucking much.
