Upper Lake Mary Dam Access provides two paved boat ramps with adjacent parking and picnic facilities (tables, ramadas, grills) for day-use access to Arizona's largest twin lake near Flagstaff.

The site requires a day-use pass ($10/vehicle) and is accessible via paved Lake Mary Road, making it suitable for all vehicle types; note that there are no restrooms or potable water available at this specific access point.

This location is popular with both motorized and non-motorized boaters, with the deep end near the dam being particularly good for observing waterfowl and raptors.
