Lester State Ultralight Flightpark covered an area of at an elevation of 1,693 feet above mean sea level. It has one runway designated 5/23 with a turf surface measuring 400 by 100 feet. It also has one helipad designated H1 with a turf surface measuring 100 by 100 feet.
In 1989, the Green River washed away the runway, but it remained listed; the 2016 Airport/Facility Directory noted the runway was "closed indefinitely due to severe erosion from the river", and the grass helipad was available for emergency use.
