The Columbia River Gorge in Oregon is a treasure trove of waterfalls. As you drive along the historic Columbia River Highway, you'll find many waterfalls. Multnomah Falls is the most beautiful and popular one, with Horsetail Falls holding its own with its beauty. With a 176 foot drop, the fall comes together then fans out to resemble a horse's tail ... so its name is very fitting. One thing they all have in common is that beautiful sound and the freshend air of a waterfall ... so peaceful and relaxing.
