Its always a good idea to stop at the local parks head quarters before going into an area that your not familiar with, many of the trails in the park have requirements like number of persons in your party, related to the number of campsites, you cant just pitch a tent in any old place, also theres a requirement to have a bear canister to store your food and anything else that has a sent, you rent the canisters at the park headquarters in port angeles, plus there is a fee for the permit, think we paid around 6 dollars each, that included the bear canister, hiking in the ALW requires a permit that is free, its at the trailhead, fill it out with names of persons names in the party, nights spending out return date, however theres a trailhead parking pass that you will need at any national forest trailhead.
