Ruins of one of Thailand's oldest Lanna cities — 8 km of ancient city walls, dozens of crumbling temple ruins, and a small but excellent national museum. Almost no tourists come here.
Local tip: Genuine archaeological magic, and almost completely overlooked. Combine naturally with the Golden Triangle (20 minutes further north). Don't make it a standalone 120 km round trip from the city.

Most places on this list sit outside the city and have no return Grab, so plan the ride before you go — see how to get around Chiang Rai for what each option costs. If you would rather not work out the logistics, a local operator runs a shared day tour that links the main sights with hotel pickup: how a full day in Chiang Rai usually runs.
