​​Mix Canyon is a short but very challenging climb near Vacaville, CA. The grade increases with each mile – mile one is 5.8%, mile two 8.8%, mile three 12.8% and, finally, the coup de grace - a whopping 13.4% for mile four. There are not many dramatic views (a couple of opportunities eastward down towards the Vacaville/Fairfield area towards the top). What makes this climb notable is the significant and difficult grade over the lasts two miles.

Roadway:  The road is in average condition as of 2020.  Caution must be exercised on the descent as there are rough spots on the road, potential debris and a couple hairpins that you approach at a double digit grade.

Traffic:  Minimal.

Parking:  There are many spots to park along the road on the way to the climb.  We have parked at the corner of Mix Road and Pleasant Valley Road and warmed up for the ~mile to the climb start.  Map; Street View. 
Provisions:  There are no spots for food or water along the climb.  It can get hot in this area during the summer so bring plenty of water. 

Equipment:  Bring a bike with gearing to suit your climbing ability - this is a very steep and difficult bike climb.

Mix Canyon is what I would call a "novelty climb". It's just ridiculously steep at the top. How steep? It's, "don't lean back or you may loop out" steep, it's "don't stop because you will have a very hard time getting clipped in again" steep. I love it, there are almost no cars and no fast cars (the switch backs are too tight to go fast) and it gets really hot due to lack of wind during the first half when the walls are really on top of you. At the top, you can go through the gate and take the gravel road (blue ridge road) over to Gates Canyon or turn around. If you can, I recommend going to Gates. The gravel is pretty loose but doable on a road bike (maybe a slight hike a bike the first 1/4 mile with skinny tires). The view is great and Gates is a better descent. Going back down Mix is no fun for the first half. You just have to ride the brakes the entire time and hope your pads are good! Overall, a ridiculous climb but well worth it once a year or so.

A very unique climb, narrow, hidden and goes nowhere but one you definitely want to do if you like steeps. The last half is difficult climbing through a few tight turns. The descent is hair raising and can be challenging.

Ride a mere four miles, but at a stout 10.5% average grade.

​​Mix Canyon is a short but very challenging climb near Vacaville, California and is the seventh steepest 2.5 mile road bike climb segment in the U.S., and the steepest in California.

The finish is at the “Y” up to the radio towers (left) and Blue Ridge Road (right).  

     There are no Top 100 rides in the near vicinity and this is not a “destination climb,” but it is a unique ride that is worthwhile if you happen to be travelling through or live in the area.

Traffic and Roadway Surface Report:  The roadway is very narrow, essentially a wide one-laner the entire route.  The roadway surface is in moderate to somewhat poor condition in spots.  However, despite being fairly narrow, the road is safe as it has very little traffic.  The descent is technical and caution is mandatory due to the incredibly steep grade and narrow width of the roadway. The road dead-ends at a no trespass sign at the top, about 4.75 miles from the beginning of Mix Canyon Road.

Spooky at the end on a late finishing night 9-25-15.

“Mix Canyon is one of the most difficult climbs in California nad the United States over a similar length.  Somewhat isolated, the first mile is fairly shallow but things get more difficult as you ride over a variable grade.  There are a few houses along the way but you should encounter little if any traffic on this very narrow route.  Soon the grade reaches double digit and stays there as the last 2 miles you will likely remember as they are steeper than California icons Bolhmon/On Orbit and Old Priest Grade and feature one of the most difficult miles in cycling.  The entire route resembles some European climbs as it is over a narrow, single lane.  Near the top are several severe switchbacks that will also get your attention, one of which contains the maximum grade of the ascent.  Towards the very top riders also receive views down into the valley.  The grade finally eases over the last 0.2 miles and at the very top the road turns into dirt in a pleasant setting.  Due to its steep grade and twisty route Mix Canyon is a technical and difficult descent as well.”  (This quote is presented with the approval of John Summerson, from his book, The Complete Guide to Climbing (by Bike), 2nd Edition, pg. 132.)
