This book uses beautiful photography and extensive research to describe the best and most-important preserved natural areas in Pennsylvania. The locations feature outstanding old-growth forests, wildflower preserves, waterfalls, natural beaches, deep canyons, wildlife, wetlands, glacial bogs, and wilderness areas. Other locations have the best outdoor recreation, ranging from bird watching, hiking, biking, and fishing to more-adventurous activities, such as rock climbing, whitewater rafting, hang gliding, and ice climbing. This book will be invaluable when planning your next Pennsylvania adventure. A few examples of experiences you will never forget are witnessing 50,000 snow geese take flight in unison, bull elk bugling during mating season, and the Milky Way at one of the darkest night skies in the East, or visiting the oldest human-inhabited archeological site in North America, an avian research center that bands more than 10,000 birds annually, and Pennsylvania’s largest fish hatchery.
