Here are twenty wilderness hikes within twenty miles of downtown Portland, Oregon, less than a half hour"s ride from the city. Adventurers at all skill levels will be surprised by the remoteness and remarkable beauty of these easy woodland escapes. Just take this pocket-sized companion and slip down a hidden trail to emerge on vistas with eagles soaring overhead. There are shorter walks suitable for kids, like the McCarthy Creek Loop, and rugged routes for the ambitious, like the Fire Lane 12 loop. Each hike description includes a map, bus access, basic conditions, length, and grade, as well as flora, fauna, geology, and local history. Half the trails explore lesser-known wooded hillsides in Forest Park. Others venture farther north in the Tualatin Mountains into rarely described prime Oregon hiking country. A devoted advocate for Portland"s wilderness areas, James D. Thayer has surveyed most of the publicly accessible walking routes along the Tualatin Mountains from Forest Park to Scappoose and nearly to the Oregon coast-on foot.
