      ANSA is a private club with 501(c)3 status, formed to support Nordic skiing and related winter recreational activities in the Auburn area. We maintain both groomed Nordic ski trails and snowshoe trails on the property of the Lost Valley Ski Resort, and surrounding private properties, in Auburn.

      Please visit our website and facebook page at the links below for detailed information on ANSA and its activities.

      ANSA works in partnership with Lost Valley Ski Resort to maintain these trails – most of the land is theirs. Please support Lost Valley whenever you have a chance. Make it a destination, and ski over for a cup of cocoa or a burger and a beer.

      See you out on the trails And LET IT SNOW!

      Access Info:
      Parking is available at the Lost Valley Ski Resort and, for members, in the trailside lot (1465 Perkins Ridge Rd by GPS) or across the street in front of the apple pickers’ bunkhouse. Please avoid parking on Perkins Ridge Road if at all possible. Cars come fast and aren’t always looking for roadside pedestrians.
      Using the trails is on the honor system. We’ve decided as a club not to spend money on passes or tickets. Instead we encourage honesty by all who use the trails. We hope that people will pay what we believe is a fair fee to support and maintain these great trails, and we appreciate your support. Please follow the Membership link below for more information on membership fees and day passes.

      Friends can join you for a ski or two, but beyond that we encourage them to join ANSA.

      Others who come to ski the trails for a day should please go to Lost Valley Lodge and purchase a day pass.

      Trail maps are available on Trailforks, on our website, and on the kiosk at the parking area.

      Signs now mark all intersections and give the shortest and easiest routes back to the Lost Valley lodge.

      We encourage you all to read the trail etiquette section on our website.

      Please please please don’t walk on the trails. The divots you leave take a long time for the volunteer groomers to smooth out. If you must, for some emergency reason, please stay to the very edge of the trail or just off it.

      Pets are not allowed on ski or snowshoe trails. They will also leave marks and poops that take a long time to fix.

      Fat bikes are not allowed on our trails. Our trails are groomed by snowmobiles, so are too soft to be fun for fat bikes, and the ruts you leave… you guessed it!... take hours of volunteer groomer time to smooth out, and are dangerous to skiers.

      Snowshoe Trails: There is a network of snowshoe trails that are another fun way to get out into the woods. Do not snowshoe on the ski trails – stay on the snowshoe trails only.

      Days are short, so many members ski before dawn or after dark by headlamp. This is allowed, and actually great fun with the current generation of headlamps, but we encourage you to take precautions like skiing with a buddy and having a cell phone available.
