Tara and I took Lukla on a 10 day roadtrip through Oregon in the Autumn of 2015. We visited the Columbia River Gorge which has a large number of waterfalls including the most recognisable Multnomah Falls. We spent time around Mt Hood, Bend, Crater Lake and the Painted Hill and then on the way back, we stopped in at Silver Falls State Park, East of Salem. I think we were a week or two early to capture the best Fall colours to go with the Falls, but exploring around so many majestic waterfalls was still a real pleasure.
