The sheer size of this well-preserved dwelling inspires visitors to imagine how the Sinaguan people lived centuries ago. The monument is actually a misnomer, as the Sinaguan people occupied this terrain pre-Colombus and pre-Montezuma. The "Castle" in fact functioned much like an apartment building: a communal living space with multiple dwellings. While visiting, you may look up and wonder why the dwelling is so high up; while there is no doubt safety from invasion built-in to this location, researchers also believe the situation helped avoid seasonal flooding brought on by monsoons.
Additionally, do not miss the Montezuma Well. What appears to be a mere pond is filled with 15 million gallons of daily-refreshed water, percolated over millennia and fed by what was once a subterranean flowage. View additional dwellings and prehistoric structures around Montezuma Well, and hike down along the well's outlet into Beaver Creek.

Another well-preserved Sinaguan ruin, Tuzigoot is a perfect place to explore the landscape and history of the valley. Featuring a small museum, ruins, and Tavasci marsh (yes, a marsh in the desert!), the Monument is well connected by accessible walking trails. After your visit, follow the road in to one of the many river access points. At the very least dip your toes in the historic river; however, if you have time, renting kayaks or taking a guided trip with one of the many companies in Verde Valley is highly recommended.
