Very twisty road, some road snakes (tar) and most corners are blind. Two lanes most of the way, some guard rails but a lot more drop offs, great views and hardly any traffic on a week-day. Lots of curves keeps you on your toes, rides differently in each direction. Keep going onto Glendale Ridge Road for single lane curves a-plenty up to Mt. Baldy. Great half day ride!
Start in Glendora, go up Glendora Mountain Rd, across Glendora Ridge to Mt Baldy and down My Baldy Rd to Euclid Ave in Upland.
Great technical curves, nice scenery, little traffic.
Hazards include: rocks/gravel/sand on road, no lane dividers, narrow roadway, idiot drivers, wildlife.
