Hovenweep National Monument is a little "off the beaten path"(about 30 miles via the route we took) but well worth the drive. The Visitor's Center is located near the head of a canyon where there are about a dozen stone structures. The level of craftsmanship and effort is really remarkable. According to the trail guide these buildings were constructed around 1200. Unlike other sites where the buildings are under the canyon rim or in alcoves, the structures in Hovenweep are in the canyon or on the rim. The precision of the stonework is impressive. There is a concrete sidewalk that leads to a view of all the structures and there is a "path" around and through the canyon that can be done in about an hour. The path is not handicapped accessible in my opinion as it is laid out over the native rock.
