California Top 10 Most Scenic Bike Climb

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.

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.
