Waianapanapa State Park in Hawaii began requiring entry and parking reservations for non-residents. State officials hope the managed entry will reduce illegal roadside parking. Trails elsewhere in New York's 6 million-acre Adirondack Park remain reservation-free but hikers throughout the reserve are now checked in by staff in the parking lot and at the trailhead. She was advised to return between three and five hours later. There, too, she encountered a wait but was able to enter after an hour.
after the check has gone, the park will be open.
