Climb Summary

PJAMM cyclist riding bike up Glendora Mountain Road from Glendora CA

In our opinion, Glendora Mountain Road is the most scenic cycling climb in Southern California.

Cycling through San Gabrial Canyon

 This is the more scenic alternative to the Mt Baldy Road route.  This version of the Mount Baldy bike climb begins at the corner of E. Sierra Madre Avenue and Glendora Mountain Road in Glendora, California.

The beginning of bike climb up Glendora Mountain Road - street sign

This bike climb is not a Top 100 US climb because it has 1,115' of descent which takes it out of the "nearly all" continuous climb category. It would rank #97 on the Top 100 US  list if the descent were eliminated - it is a tough climb.  GMR, as it is referred to in Southern California, begins its ascent between Mt Baldy Road to the East and Hwy 39 (Dawson Saddle and Crystal Lake) to the West.  This climb shares its last 4.5 miles with the Mt Baldy climb. .

Summary from 2015 Tour of California Website:

            “Route Information: May 16, 2015 - Stage 7 Finish

The climb up to Mt. Baldy is an integral part of the Amgen Tour of California’s nine-year history. Since 2011, when it was first introduced as the race’s first true mountaintop finish, the steep switchbacks up to the Mt. Baldy Ski Area at 6,500 feet elevation have served as the deciding factor in crowning the overall champion. Due to overwhelming demand from the fans, Mt. Baldy is back for the Amgen Tour of California 10th Anniversary after a two-year hiatus!
Mt. Baldy is located 45 miles from downtown Los Angeles and is a popular location for hikers, sightseers and cyclists. During autumn, spring, and summer you will find hundreds to thousands of outdoor enthusiasts traveling Mt. Baldy every week to summit the tallest peak in Los Angeles County, Mt. San Antonio (Elevation 10,068 feet), which is accessible from a trail network originating at the Mt. Baldy Ski Area. For those who prefer a two-wheeled adventure, cyclists from far and wide visit Mt. Baldy to climb the challenging switchbacks, which ascend over 2,000 in only 4.3 miles (9% average gradient). In the winter months Mt. Baldy is known for its steep ski terrain and easy access from the big city below.”
