Backpackers: If your trip starts while the shuttle bus is operational and ends after the shuttle bus season, please notify the staff at the Minaret Vista when you arrive. You will be able to drive into the valley. You must provide your wilderness permit as proof of your trip plan and must pay the standard amenity fee. Wilderness permits are not available at the Devils Postpile Ranger Station.
