Look closely at your reservation documentation. There is a number in the reservation details that you must call sometime within a week of arrival to Steep Ravine. You need to obtain the gate code prior to departure -- there isn't much mobile / cell service out on the coast.
Call ortextranger station
You can also get it from the ranger station up at pantoll campground, during business hours
Call Reserve California with your reservation #, you'll need both cabin code and gate code.
