It's the national Park pass. You can get it at the visitors center or forest service office
Should be able to get it anyplace that sells the day pass. You should also be able to purchase one at the ranger station.
There are a number of places in lake arrowhead besides big bear discovery center or the district office on tippecanoe in san bernardino. Any sporting goods store. Up here at the Valero stations, cedar glen hardware store, lake arrowhead chamber in the villiage. The sky forest ranger station is a work center and is closed. Day passes are $5; 2nd car is $5 annual are $30. If you are a senior it is a lifetime pass for $80 which can only be had at BBDC or SBNF district office.
I think you can buy one there when the office is open.
Im not sure either.
