At the heart of the northern uplands, Chiang Mai is both an attractive historic city and a vibrant cultural centre, with a strong tradition of arts, crafts and festivals.While the overriding enticement of the surrounding region is the prospect of trekking through villages inhabited by a richly mixed population of tribal peoples. Plenty of outdoor activities and courses, as well as hot springs and massages, can be enjoyed at Pai, a surprisingly cosmopolitan hill station for travellers.
