The town, which is named for Montezuma, the Emperor of the Aztecs, consists largely of historical buildings and houses lining unpaved streets at the end of the paved county road that ascends the Snake River from Keystone near the west side of Loveland Pass. The town sits in a high steep valley surrounded by forested peaks offering good access to higher national forest land destinations. The paved road up from Keystone leads mainly through national forest right up to the entrance of town, which is marked by a sign over the county road.
