Montezuma Well is a sub-unit of Montezuma Castle.  This is a unique area in both a biological and geological sense. The area itself includes the Montezuma Well, which is an attraction in its own right.  There is also a very pleasant trail along the drainage stream from the Well, a National Park Service trail along the desert surrounding the Well, and a ranger station with restrooms. Just around the corner is a great picnic area has its own birding trail.
