This is one of four excellent bike climbs near Lexington Reservoir off of Highway 17. This climb runs near the Sierra Azul Open Space Preserve, home to Santa Clara County's greatest bike climbs. 

"Soda Springs Road is a steady and severe dead end climb between the towns of Los Gatos and Santa Cruz in the Bay Area. Trees close in quickly as the grade slowly ramps up over the initial section. Once up to its average the slope is unrelenting and fairly steady but never severely steep. A very narrow and twisty road takes you through a hillside neighborhood to its dead end top which can be a welcome sight. Due to its twisty routing Soda Springs is a somewhat difficult descent as well." (This quote is presented with the approval of John Summerson, from his book, The Complete Guide to Climbing (by Bike) in California, pg. 243.)
Average grade is 8.2% with 0 descent. 71% of the climb is at grade 5-10% and 21% is at 109-15%.  The steepest quarter-mile running at 10%, and steepest full mile at 9.1%.

Climb summary by PJAMM’s John Johnson.

Soda Springs Road is the one of four excellent Lexington Reservoir climbs that begins on the reservoir side (east) of Highway 17.  This one is a true single lane road which is in great shape and sees very little traffic, other than by cyclists (2,320 attempts on Strava as of March 27, 2016) and the few residents along the route.  The climb is a bear and #4 in the Santa Clara/Santa Cruz County areas.

Before heading to Santa Cruz County on your cycling adventure, be sure to rely on our list of Things to Bring on a Cycling Trip, and use our interactive checklist to ensure you don't forget anything.

Unfortunately, although the road continues from its paved finish, the gate is locked and our Santa Clara cycling consultant answers my question about continuing on past the gate as follows:

There is a locked gate at the top of Soda Springs, unfortunately.  I've never been past the gate, sometimes I ignore "private road" signs but I don't like to jump gates.  There are houses near the gate, as you climb, and it looks like there are houses near the gate on the other side, so it is likely somebody would see if you jumped the gate.  Soda Springs does come close to Mt Thayer and Mt Umunhum and I'm sure the roads probably do connect, but there are gates on both sides so I've never attempted it. I did read online some guy jumped the gates and took a mountain bike the whole way, but it sounded sketchy. So unfortunately, I don't know any way from Soda Springs to Mt Umunhum.

A spectacular climbing day:  Black - Gist - Thompson - Montevina - Soda Springs Roads (Map) - essentially no traffic and quiet riding/climbing of 41 miles, gaining nearly 8,000'.  ​

​Roadway Surface and Traffic Report:  This is a true one lane ride (sometimes just barely that) which is in good shape with next to zero traffic the entire climb - this is a safe climb.​

That’s a wrap!!
