Lichau Road Bike Climb - PJAMM Cycling

Lichau (pronounced Leech-Ow) Road is a little known cycling treat in Sonoma County. Located off Roberts Road near Sonoma State University, Lichau can be included in a nice loop or done as it's own climb. It starts mild and ramps up with steep turns and cattle guards quickly.  The challenge is balanced by the great view of Rohnert Park you have to the west as you climb.  Once you turn right the road feels harder than it looks as this sections is known as 'gravity hill.' A few milder pitches and you end at a gate just past the nature preserve to the right. Be careful going down as it can be bumpy and cars often speed up the road and take wide turns.
Average grade is 8.4% gaining 400' with 0 descent.  12% of the climb is at 0-5%, 59% at 5-10% and 29% is at 10-15%. The steepest quarter mile is 11.8%.

Cycling Lichau Road, Sonoma County, California.

Ride three miles gaining 1,310’ at 8.4% average grade.

Lichau Road (pronounced Leech-Ow) is a little known cycling treat in Sonoma  County.  Located off Roberts Road near Sonoma State University, Lichau can be included in a nice loop beginning in Santa Rosa that includes some great climbs and scenery (Map ​and includes Cavedale Road).


Lichau Road has a section known as "Gravity Hill" because down is up and up is down (essentially, this is caused by an optical illusion).  Watch the slideshow with a photo of an apparent descent, that is actually a 1.7% ascent to see for yourself.  This climb offers views of open fields, some vineyards, and Rohnert Park/Cotati to the west.

Traffic and Roadway Surface Report:  The roadway is in good shape and is two lanes for th  first half of the ride, and turns to single-lane and is rougher towards the top.  There is mild traffic for the first couple miles but very little the last mile.  There are ruts and loose gravel at the top, so caution descending is advised.

That’s a wrap!!
