Off the Truckee River Trail in the Pyramid Lake Paiute Reservation, Nevada. The Truckee rises from the overflow from Lake Tahoe, in the Sierra Nevada, and ends at landlocked Pyramid Lake, flowing thru Reno, NV along the way. The Truckee River Trail is intended eventually to follow the river along its entire length, but there are still gaps at present due to landowner issues. In the Reservation, the trail at first follows an old railroad grade, veering off eventually to go down to Pyramid Lake. You can buy an online parking permit from the tribe to hike or bike on the parts of the trail that are on the Rez. Just leave the permit on your dashboard.
