One of the best rides you will have anywhere in the world. From valleys into the mountains, rice patties and tea fields. This is an amazing to trip to do over 3-5 days. Curvy, hilly, challenging with some of the best scenery around.
Awesome ride through the national park. It's like riding through the Forrest of Jarasic Park, but with a really winding road. Can't recommend it enough, whenever I have to ride to Phuket this is def the way to go.
