Dont waste your time searching your way around Chiang Mai and northern Thailand. I can highliy recommend to leave all the planning, thinking and arranging to Wilai. She is a great guide, with excellent English, lovable, cultivated, honest and truly loves her country. We spent a great day exploring the National Park, Waterfalls, the Karen-Tribe and much more. Every minute was a pleasure. We will be back for sure. Thank you Wilai and all the guys who worked with her!
