This is PJAMM Cycling’s home climb. We have ridden this wonderful ride well over 100 times and it never grows old. This is the best climb in and around our hometown of Santa Rosa, California, offering great views, challenge, and the backside of the climb boasts the title of best repeat hill in Sonoma County, (in our opinion).
While Los Alamos frontside ranks only #18 in Sonoma County, don’t let that low ranking deter or fool you. This is a tough climb, made all the more challenging if you drop down the backside to the trailhead to the western entrance to Hood Mountain Regional Park. The climb begins within the Santa Rosa city limits and is a favorite of local riders/climbers. There are brief vineyard views at the beginning of the route, but the primary scenery is canyon, pasture, and wild oak along a fairly steady climb for 3.5 miles at 7.1% average grade -- a good work out.
Working our way up the hill -- photos are in order clockwise from top left.
Curve at mile 0.7.
¼ mile at the half-way point averaging 13.5% (spikes to 16%).
This is just a very pleasant and pastoral, albeit tough, climb.
The old Hillman Ranch - about a quarter mile from the finish.
