Glendora Ridge Road

Distance: 43 miles out and back
Elevation gain: 4930 ft

Our Southern California ride list has three rides that are all big, chest-thumping rides up a mighty mountain: Mt. Figueroa, Gibraltar Road, and Glendora Ridge.  Of the three, Glendora Ridge is the most monotonous climb, both in pitch and scenery.    But it also has the best ridge ride, a rollicking roller coaster, often along the precise ridge spine (see photos below).  All three rides are detailed in, and I encourage you to familiarize yourself with his write-ups.

Despite the title, the ride is actually two very different rides, a long steady climb up Glendora Mountain Rd., then a roller along Glendora Ridge Rd. to the ski town of Mt. Baldy.    My computer recorded 5930 ft of vert, which puts it in the same category as Figueroa and Gibraltar, but it felt easier and I’m guessing the pitch is less intense.  Or I was having a very good day.

A word of warning: At the base of Glendora Mountain Rd. there is a sign reading “No Reckless Driving.”  How odd.  Are there roads where reckless driving is welcomed?  I am reminded of one of my favorite signs near my home, “No illegal dumping here.”  But that sign is LA-area code telling you that GMR and GRR are favorite sports car enthusiasts’ proving grounds, where racer wannabe’s come to hone their skills.  When I was there, the place was deserted.  But see Michael H’s comment below.  On a weekend day in fair weather, it might be a bit hairy.

Begin at the intersection of Glendora Mountain Rd. and E. Sierra Madre Road.  Ride up Glendora Mt. Rd.   The road is a very consistent pitch all the way to the intersection with Glendora Ridge Rd. 9.7 miles in, and the flora is unaltered San Gabriel Mountain shrub.   From the get-go you’re in canyon, so the views to the south, which you might imagine would be expansive vistas of Pasadena and points south, are in fact mostly a lot of canyons and ridges (see first photo below).  Can’t compare with the views of Santa Barbara, the Channel, and the Channel Islands on the Gibraltar Ride.

At the intersection, go R onto the ridge road and ride to the intersection of Glendora Ridge and Mt. Baldy Rd. and the town of Mt. Baldy.   The joy here is the road contour: it’s up and down and back and forth, mostly up on the ride out, often teetering on the knife-edge of the ridge—as good a ridge ride as I know of.

Mt. Baldy is a ski town, which means it might be pretty buttoned up if you arrive out of ski season, but just into town on the R is Mt. Baldy Lodge, a knotty-pine-and-moose-head restaurant that caters to cyclists (just past a prominent white sign reading “Mt. Baldy Lodge Store”).  When I got there it looked closed, but I banged on the door desperate for water, and the owner came out and said, “Oh, riders know just to come around the back onto the patio,” opened up, and fed me cheerfully.

The ride back along the ridge is pure joy, almost all of it at a slight descending pitch that makes you feel fast and strong as you pedal through the corners.  The ride down Glendora Mountain Rd. is straighter, faster, and more monotonous.

Shortening the route: Drive to the intersection of Glendora Mountain Road and Glendora Ridge Road and ride GRR.

Adding miles: At the intersection of Glendora Mountain Rd. and Glendora Ridge Rd., Glendora Mountain continues on down the back side of the ride for about 7 miles to East Fork Rd.  It’s very much like the riding on the front side, perhaps a tad steeper and drier.   Going L on East Fork (a nearly flat, pleasant enough road) takes you to San Gabriel Canyon Rd., a big road with shoulder but lightly trafficked, which you can take L for a long, gradual, and fairly pleasant descent back to your car, if you prefer loops to out-and-backs.  For a pretty little break in the intensity, check out the West Fork Scenic Byway, about a mile to the R when you hit San Gabriel Canyon Rd.  It’s almost a rec path, a closed road (go through the anti-car gate) along a charming trout stream.  You’ll only have to share it with two or three fishermen.

In the town of Mt. Baldy you’re looking at an infamously nasty climb of 4.6 miles up Mt. Baldy Rd. to the Mt. Baldy ski area.  This is the stretch of road often used to separate the sheep from the goats in the Tour of California.  The Tour stage route incorporates everything on our ride, almost everything discussed under Adding Miles, and more.  Those guys are nuts.

    A Bestrides user writes: “I’m surprised you didn’t put Mt. Baldy (all the way to the ski lifts) as one of the best rides of California (supposed to be very similar climb to Alp d’Huez) and not the ride up Glendora Ridge Road but up Mt. Baldy Road. For the consistent grade and length, it’s a climber’s dream!” I haven’t done it, but my sense is, it’s more work and less fun than the route I’ve mapped, but it’s certainly legendary.

    This is one of my favorite rides in California. I would recommend that any cyclists bring their best defensive riding skills. I didn’t have any close calls, but I’ve heard some motorcyclists and cars treat this road like a race track. A car had driven off Glendora Ridge Road an hour or two earlier when I was riding up on a Saturday in April 2021.

    Rode this route on July 3. The road was closed to vehicle traffic to prevent fires in the bone-dry brush. The closure made it an incredibly safe ride. The only negative was 100F temps on the tarmac in a few parts, but there is indeed water at Mt. Baldy Village.

    Glendora Mountain Road is easily the best ride in Southern California. And I’ve done them all!
