Doi Inthanon National Park

Thailand's highest peak, Doi Inthanon (ดอยอินทนนท์) soars to 2565m above sea level, an impressive altitude for the kingdom. Surrounding this granite massif is a 1000-sq-km national park, dotted with hiking trails and waterfalls and enveloped in an impenetrable curtain of jungle. When the heat of Chiang Mai gets too much, locals decamp to Doi Inthanon for day trips, especially during the New Year holiday when there's the rarely seen phenomenon of frost at the summit.
