We spent a weekend exploring Portland Oregon and the Columbia River Gorge. The Multnomah - Wahkeena Loop Trail was a very pretty hike with over 10 named waterfalls. It's crowded at the start and finish, but the middle section was pretty peaceful. The Indian Point hike gives you great views of the Gorge, but I'd avoid taking Nick Eaton since the views aren't that great and it's more climbing to the top. Ainsworth State Park is located near Horsetail falls and includes RV spaces, pack in tent sites and hot showers!
