Cycling Sonora Pass - one of our favorite Sierra Nevada bike climbs.
Ride 9.1 miles gaining 3,426’ to elevation 9,655 at 7% average grade.
This is a short but stout climb in a fairly remote area of the Sierra Nevada Mountain Range. While we think the sign at the beginning of the climb is an exaggeration (26% grade), this climb will test you in a few spots, including 10%+ grades at the very beginning for 1/2 mile. Miles .5-3.0 average 10.0%, and there is a 3/4 mile stretch from 6.0-6.75 that averages 12.3%. As can be seen from the YouTube Playlist , the views along this climb of high sierra forest and granite rock faces are spectacular. The climb can be done as an out-and-back 2 climber by going down the east side of Highway 108, then back up Sonora Pass East.
“The oldest trans-Sierra emigrant trail to California crossed over the spectacular Sonra Pass.”
Hwy 108 over Sonora Pass closely follow the old Sonora & Mono Toll Road.

Mile 6.5 - 2.6 miles & 690’ to go at 5.1%.
The Pacific Coast Trail crosses the summit of Sonora Pass East/West.
Traffic and Roadway report: The roadway surface is excellent throughout this ride and although there is minimal shoulder, traffic is light and this seems to be a safe ride.
We stayed in Sonora in preparation for our climbs from the east and west to the Sonora Pass and stayed at the Gunn House which was a modest but decent place to stay.
That’s a wrap!!
