Phrae is often overlooked when visitors come to Northern Thailand, and there lies its quaint charm. The old city is surrounded by a moat and within are some preserved and restored teak houses. Phrae was once the main provider of teak before the logging industry became extremely restricted in preserving what’s left of the teak forests. Besides its quiet, tree laned charm, Phrae is most famous for Phae Muang Phi, an unusual spot in Northern Thailand with its famous rock formations. Its original name means “city of ghosts” and is commonly thought of as "Thailand’s Grand Canyon" for its distinctive mushroom-shaped formations and pillars shaped by natural erosion.
