Upper Lake Mary #1 is a paved boat ramp located 12 miles southeast of Flagstaff with a paved parking lot and picnic facilities available on a first-come, first-served basis.

A day-use pass ($10/vehicle) is required, and swimming is prohibited within 50 feet of the ramp.

The site offers access to Arizona's largest of the twin lakes, popular for both motorized and non-motorized boating, though restrooms and potable water are not available.
