Timed use permits will be required for each personal vehicle accessing federal lands adjacent to the Waterfall Corridor of the Historic Columbia River Highway from just east of Bridal Veil to Ainsworth State Park between 9 a.m. and 6 p.m. each day beginning on Tuesday. Columbia River Gorge National Scenic Area Recreation Officer Stan Hinatsu says this is a pilot project in partnership with Oregon State Parks, the Oregon Department of Transportation, and Multnomah County to try to deal with the increase in visitor use of public lands. Daily permits are available for a $2 transaction fee at recreation.gov, and a limited number will be available each day at no cost at the Cascade Locks Historical Museum and at the Gateway to the Gorge Visitors Center in Troutdale.
