You should be able to get one at most USFS Visitor Centers, USFS District offices, NPS Entrance Stations and NPS Visitors Centers. You can purchase them at REI as well, but they can be hit or miss though if they have them on hand. And you can buy them online here: http://store.usgs.gov/pass/index.htmlrobow8 wrote: Sweet.

We bought ours at the gate of Yosemite last April as my previous one had expired the month before and our trip up there was at the very beginning of the month.
