Southeast of Truckee, the Martis Peak Lookout route is a 4 mile one-way trek.
To reach the mountain biking trailhead from Truckee, head south on SR267. Turn left 1/2 mile south of Brockway Summit on a dirt road and park here.
The mountain bike ride (4 mi./ 1650) is a steady climb on a good dirt road with a rewarding 360 degree panoramic view at the top from the old fire lookout. Follow the main road which is marked with orange diamonds (the road serves as a snowmobile and popular cross country skiing route, and these markers, often high in the tree, serve to guide them during the winter months).
Overall, Martis Peak Lookout is the 54th most popular mountain bike trail of all 132 mountain biking rides in California.
