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 beginning in Santa Rosa that includes some very nice climbs and scenery (Map and includes Cavedale Rd) .
Lichau Road has a section known as "Gravity Hill" because down is up and up is down (see slideshow with photo of an apparent descent that is actually a 1.7% ascent). This climb offers views of open fields, some vineyards, Rohnert Park/Cotati to the west, Marin County/Mt. Tam to the south, Mt. St Helena to the north, and wild flowers, moss covered oaks and tree covered single lane road towards the top.

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