When are bears most active?
Bears are most active in autumn (September–November) and late spring, and around dawn and dusk. In years when acorns and beech nuts fail, they roam farther and appear closer to trails.
Hike safely
- • Make noise (a bear bell, talking) to avoid surprise encounters.
- • Don't hike alone; avoid dense brush and dawn/dusk if you can.
- • If you meet a bear: stay calm, don't run, back away slowly.
