Getting there
Get directions on Google Maps →When are bears most active?
Bears are most active in autumn (September–November) and late spring, and around dawn and dusk. Poor acorn years push bears closer to trails.
Best seasons to visit
Each season has its own appeal. Bears live here year-round, so carry a bell and stay aware — especially in autumn.
Spring · Apr–May
Fresh green & blossoms
New foliage and comfortable weather — one of the easiest times to hike.
Summer · Jul–Aug
Cool valleys & forest
Shaded trails and streams offer relief from the heat. Bring sun protection and water.
Autumn · Oct–Nov
Autumn colors
The most scenic season, with brilliant fall foliage. Bears are also most active — carry a bell.
Winter · Dec–Feb
Clear, quiet views
Crisp air and long views; quiet trails (some routes close due to snow).
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.
