Experienced and novice hikers alike will benefit from the information in this updated and expanded edition of the best-selling The Hikers Guide to O'ahu. The author describes in detail 52 trails that will take you to O'ahu's lush valleys, cascading waterfalls, windswept ridges, and remote seacoasts. Although 8 trails from the previous edition are no longer open to the public, 10 new hikes have been added. Included for each hike are directions for reaching the trailhead, a detailed route description, and information on the length of the hike, degree of difficulty, and trail conditions. For GPS users, UTM coordinates have been added for the midpoint or endpoint of each route. An expanded notes section will help readers identify geological features, historical points of interest, and commonly encountered plants and birds along the trail.
