Aside from Bunny Flat, all Mount Shasta Wilderness trailheads are CLOSED (winterized) for the season. You may still access these trailheads, but your paperwork (summit pass and wilderness permit) must be attained at either the Mt Shasta or McCloud ranger stations.
Questions can be directed to our very helpful front desk staff at 530-926-4511 or email Nick at nicklaus.meyers@usda.gov
