Hundreds of these "condos" were built into and alongside the limestone cliffs of Walnut Canyon some 800 years ago by the Sinagua people. By 1250 AD, just 200 years after they were built, these homes and the canyon were abandoned. As you walk into the canyon, you can see the homes everywhere - what a thriving community it once was! Bring binoculars to enhance the experience. Best on a weekday, early, before the crowds - for an intimate moment with the spirits of this ancient civilization. Excellent visitors center & museum staffed by friendly & knowledgeable docents and rangers.
