The main campus of Chiang Mai's famous public university occupies a 2.9-sq-km wedge of land about 2km west of the city centre, partly covered by forest and open greenery. It's a peaceful place to wander and there are bike lanes throughout the campus and plenty of cafes for pit-stops.
The entry fee for tourists – introduced after Chinese tourists started dressing up in school uniforms and sneaking into classes! – is charged at the Information Center near the Th Huay Kaew entrance; this includes a tram ride to the Ang Kaew reservoir in the grounds.
