The name Kamphaeng Phet literally means “strong as walls” or “forts make of diamonds”.
Kamphaeng Phet is a charming balance of old and new worlds, with comfortable accommodation available in the new city, while historical attractions await visitors in the wall-encircled old city. The town also features a lively street market, and day trip attractions include nearby Khlong Lan National Park, an area of outstanding natural beauty filled with exotic flora and fauna.
