How to Use This Site

  • To plan your outdoor activities go to our "What Do You Want To Do?" section. You will find trail and trip descriptions and maps, organized by activity type, to help you figure out what to do and where to go. Some of it is on this site and the rest is on other sites for which we provide links. If you know what part of the state you are interested in, start with our "Where Do You Want To Go" section and click on a yellow marker in one of our 26 regions. That page and the yellow markers contain links to our "region profile" pages which provide an overview of public lands in a region and list books, maps, and websites for that region.
  • To find places to sleep in the boonies, go to the "Where You Can Stay" section. There is guidance there on cabins, yurts, campgrounds, etc. (We do not provide info on places to stay in towns. But you can get that from the tourism websites that we list on our "Helpful Information Sources" page and on each region's profile page.)
  • To check the status of such things as snow depths, river flows, avalanche danger, etc., go to the "Current Conditions" section.
  • To pitch in with ORIC or other outdoor organizations, check out our "Volunteering" section.

The rest of the sections in the menu in the left column ought to be self-explanatory.

We are a not-for-profit partnership of eight federal, state and private organizations. Our staff is one full-time manager, supplied by the US Forest Service, and a crew of volunteers. For more information, see our printable brochure.
