Explore Keystone State Park's Ranger Trail and hear the ranger talk about general hiking tips and etiquette. This easy, 1.25-mile trail is suitable for beginner hikers of all ages, and the guided hike will take about an hour to complete. Parking is available across the street at the front office, although space is limited and carpooling is encouraged. Dogs are welcome on the trail so long as they are kept on a leash.
