Billed as the world’s largest open-air museum, Ancient Siam covers more than 80 hectares of peaceful countryside scattered with 109 scaled-down facsimiles of many of the kingdom’s most famous monuments. Visions of Las Vegas and its corny replicas of world treasures might spring to mind, but Ancient Siam does have some architectural integrity and is a preservation site for classical buildings and art forms. It’s a great place for long, undistracted bicycle rides (rental from the admission office is 50B), as it’s usually quiet and never crowded.
