The U.S. Forest Service has implemented a reservation system through rec.gov to manage crowd size and provide assured public access to Multnomah Falls and the Multnomah Falls Historic Lodge.  Columbia River Gorge National Scenic Area Manager Lynn Burditt says the ticketing system is an attempt to ensure a sense of people able to visit the site when they want to while managing crowd sizes.  It’s available at rec.gov.  Upon arrival at Multnomah Falls, visitors must use the Interstate 84 parking lot at exit 31.  There is no parking available along the Historic Columbia River Highway by Multnomah Falls.   Give yourself enough time to arrive within the one-hour time slot reserved; early and late arrivals will not be granted access to Multnomah Falls.
