Touring northern Thailand takes you to some of the most amazing historical and natural attractions Thailand has to offer. You can get there using the regular, efficient and comfortable transport available. Air-conditioned trains run between Bangkok and Chiang Mai with large bus coaches connecting Chiang Mai to Chiang Rai. The northern provinces of Thailand are cooler and less humid than the other popular southern regions of Bangkok, Pattaya and Phuket. See the self tours article on Northern Thailand Chiang Mai and Chiang Rai for details.
