Enter your zip code. These trails are ungroomed. A single plowed road leads up to the Rim Village, with its gift shop and the restored lodge beside the cliffs' rim. Nordic skiers usually set out from there. Most turn back within a few miles at one of many viewpoints.
Skiing here is free.
But don't forget to bring a Sno-park permit to put in your car window at the parking lot. Stop here to get overnight permits if you're planning to circle the lake. Then drive another 2.7 miles up to the end of the plowed road at the Rim Village parking lot. Incidentally, if you're planning to ski around the lake, you'll end up finishing the trip at the park headquarters, so try to arrange for someone in your group to shuttle the car down there before you set out. Write the club at PO Box 7705, Klamath Falls, OR 97602 for information.
