Book excerpt: Surrounded by old-growth forests, volcanic peaks, and water in nearly all its forms--from the ocean to alpine lakes, glaciers to waterfalls--the Portland area is a short jaunt from boundless adventure opportunities, many of which can be taken in just one night. This book covers the best one- (and a few two-) night hikes within three hours of the city--perfect for hikers seeking a wilderness experience without the commitment of a lengthy backpacking trek. Trips take readers to the lush Olympic Mountains, eerie Mount St. Helens, the thundering Columbia River, and the quirky spires of Three Fingered Jack.
