INTRO

Onion Valley Road is rated the most difficult bike climb in California. This magnificent climb is located in the the heart of the Owens Valley which, with a base elevation of 4,500' and surrounded by multiple 14,000', peaks is one of the deepest valleys in the U.S. The Owens Valley is a mecca for road bike climbing and boasts the greatest concentration of Top 100 Climbs of any other area in the country. This bike climb is worth the trip to its relatively remote location.
The gradient profile tells the tale - this is a challenging climb along a relatively steady 8% grade.  65% (8.4 miles) is at 5-10% and 17% (2.2 miles) is 10-15%.  The steepest quarter mile is 14.7% and steepest mile 11%. 

See more details and tools regarding this climb's grade via the “Profile Tool” button above.
Roadway:  The roadway is in good shape except for the annoying expansion joints (linear ruts) across the road every 10 yards or so that are very noticeable on the descent. 

Traffic:  Milnimal.

Parking:  There is no problems finding parking in Independence or anywhere else along the climb route.  We have commonly parked at the start of the climb on West Market Street  (turns to Onion Valley at the west end of town)- MapStreet View
Provisions;  There is no place for food or water anywhere on the climb.  Stock up in Independence where the climb begins. 

Weather;  During the summer, you are unlikely to need more than a jersey.  In the spring and fall, you can encounter very cold and windy conditions along the climb.  Consult the PJAMM weather app for the forecast at the top of the climb before you begin and select your clothing accordingly. 
Lodging:  We have ridden seven times in the Owens Valley and have always used Bishop as our home base, but also have stayed in Lone Pine when climbing Whitney Portal, Horseshoe Meadows, and sometimes for our Onion Valley climb. 

Altitude training:  If you are interested acclimating to altitude, the best place in the Owens Valley is the Glacier Lodge out of Bib Pine 35 miles north of the start of the Onion Valley Climb - Map; Google Map + Reviews.  You could also consider Rock Creek Lakes Resort at the north end of the valley 74 miles from the Onion Valley start, but it is not as centrally located to the 10 HC climbs in Owens Valley - MapGoogle Map + Reviews - it is not as rustic as Glacier Lodge, but it is more pricey. 

See Owens Valley climb area page for 10 area HC climb, or, AllTrials Kearsage Trail from bike climb finish.

CLIMB SUMMARY

Cycling Onion Valley Road: The highest ranked road bike climb in California

Ride 12.9 miles to 9,180’ gaining 5,388’ at 7.7%

A California Top 10 Most Epic Climb.

Start climb in Independence, CA.

Onion Valley Road is rated as the most difficult bike climb in California (CA Top 10), #5 in the United States (US Top 10), and #57 in the world (see PJAMM Home Page for Top 100 World list) , with a Fiets Index score of 14.5.

This magnificent climb is located in the heart of Owens Valley, which, with a base elevation of 4,500' and surrounded by multiple 14,000' peaks, is one of the deepest valleys in the U.S.  Owens Valley is a graben “down dropped” block of land situated between two vertical faults, creating the unparalleled extended steep grades along the valley’s eastern border with the Sierra Nevada Mountains. The Owens Valley is a mecca for road bike climbing and boasts the greatest concentration of Top 100 Climbs of any area in the country.  For more information on other rides in the area, check out our Owens Valley Climb Area Page.

Eastern Sierra Mountains -- extremely steep.

The 13 mile climb averages nearly 8%, and I did not see my Garmin go below 7% over the last eight miles.  And lets just say that was looking at it (read: down) a lot!  The grade is very steady at 8-9% with some segments reaching 12% and others 7% over the last half of the climb -- that, coupled with altitude, makes this a very challenging bike climb.

When to Climb Onion Valley Road by Bike:  Well, more like when not to do the climb -- we are too close to Death Valley to be doing anything in the Owens Valley in the summer.  OK, honestly, we have done rides in and near Death Valley in the summer a lot, but do not recommend it.  The average high temperatures for the summer time frame are 92° in June, 98° in July, and 96° in  August.  We suggest May or September, as the months just before or after could put you into a snowstorm as we climb towards the top of this dead-end climb that tops out just above 9,000’.

How to Climb Onion Valley Road by Bike: Pick the right time and train well, as this is the hardest climb in California at 13 miles and 7.7% average grade (¼ mile at 13.4% and ½ mile at 11.7%).  The climb begins in Independence, California, at the corner of North Webster Street and Onion Valley Road (Strava Onion Valley segment start; Latitude: 36.80159, Longitude,  -118.20197).  We commonly stay in Bishop (40 miles north of Independence, and the start of the Onion Valley Climb) at the Creekside Inn, next to Erick Schat’s Bakery.   Together, the inn and the bakery make the 40 mile trip to the climb worthwhile.



Except for the first couple of miles, this climb averages nearly 8%  -- it is a very challenging climb.

While there is at least one climb in the area that rivals Onion Valley (U.S. 100 #7/World #69 Horseshoe Meadows), Onion Valley Road is almost uniformly considered the most difficult road bike climb in California, and rightly so.  There are no provisions along this route and the temperatures during the summer will often exceed 100 for the first half of the climb.  Cross winds are also a factor on the descent.

HAIRPIN HEAVEN

We make our way through the middle set of the hairpins.

Last hairpin, one mile to the finish.

There are eight giant hairpins from miles 9.2 to 11.8, over an average and consistent 8.1% grade.  Although Onion Valley Road’s eight hairpins fall 40 short of Stelvio’s . . . there is a bit of a resemblance, don’t you think??

Roadway Surface and Traffic Report:  The roadway surface as of October, 2019 was good and traffic has been very light the six times we have climbed Onion Valley Road between 2011 and 2019.  The only irritation are the freeze joints in the road which are noticeable on the descent (see photo above).

Those joints get old after a while on the descent.  😞

That’s a wrap!!
