Teens to Trails Choose Outside Summer Challenge participants are responsible for their own safety while completing any activities. Please be sure to choose activities that match your skill level, adventure with others whenever possible, follow all local rules and guidelines, and use appropriate gear. Youth should participate with parent/guardian permission and supervision when appropriate. Be aware of weather and trail conditions, and always let someone know your plans before heading out on any adventure. By participating in this challenge, you acknowledge and accept the inherent risks of outdoor activities.
