The fifth largest in the United States, Multnomah Falls cascades more than 600 feet into the Columbia River Gorge below. When you begin your hike, the paved walkways allow for relatively easy climbing. Rest on the bridge part of the way up and snap some great pictures. The climb becomes more strenuous as you continue from here. However, several benches are scattered along the way. Check out the Multnomah Falls Lodge restaurant, snack bar and gift shop before leaving.
