If you're 18 or older and the type of person who never gets tired of learning, Acadia's Senior Ranger Program may be just the activity for you. Senior rangers complete 7–10 activities in the senior ranger booklet and attend two ranger-led programs or volunteer with a trail crew for a day to earn their senior ranger patch. Activities include completing a challenging crossword puzzle, journaling, exploring three self-guiding trails, and more. Pick up a copy of the senior ranger booklet, available for a fee at Eastern National outlets in the park, and begin your exploration of the park!
