First timers in Thailand - we'll be in Chiang Mai for four nights in July. I'm having a really hard time deciding what we should be doing while we're here. We're young, active, interested in culture and mainly non-touristy experiences. We enjoy hiking, nature, checking out markets, and eating great food. We will be spending one day at ENP, probably on the Pamper a Pachyderm experience. What are the other must-dos for us? I've looked into hill tribes (can't seem to find something non-touristy around CM), treks, tours to temples... but it's too overwhelming. Should we break our time up between CM and Chiang Rai to experience more culture? Should we spend a night or two on a trek (worry about the weather)? I'm worried that we'll be spending too much time traveling and not enough time experiencing. What would you suggest?
