A rectangle two kilometres long either side of a long central canal, with international monasteries built or being built by Buddhist nations and orders from across the world. The east side hosts the Theravada countries (Sri Lanka, Burma, Thailand, Cambodia); the west the Mahayana schools (China, Japan, Korea, Vietnam, Tibet).
You can walk the zone in about three hours but it is more pleasant by rickshaw or bicycle from the Tourism Village. Most monasteries welcome visitors; remove shoes at the entrance, dress modestly, and avoid photographing meditating monks. The architectural variety in such a small area is unmatched anywhere in the Buddhist world — a global pilgrimage site condensed into a single garden.
