Distance: 21-mile lollipop
Elevation: 2680 ft
This strenuous little 20-miler climbs up from Hwy 1 and the ocean, then loops around to take in two classic back roads, all through picture-book Santa Cruz redwood forest. Bonny (sometimes spelled Bonnie) Doon itself is pretty famous because whenever the Tour of California comes down the coast from San Francisco to Santa Cruz it’s the climb where the winning move is made. I stood on the side of the road and watched Levi Leipheimer stick it to Mick Rogers and Dave Zabriskie on this climb one year on his way to the overall victory.

Begin at the intersection of Bonny Doon and Hwy 1. There’s a good dirt parking lot right at the intersection. Ride up Bonny Doon. It’s steep up from the get-go, so I do 20 minutes on Hwy 1 (straight, flat, relatively uncrowded) to warm up beforehand.
The road contour is not the attraction here. Bonny Doon is a fairly wide, fairly straight, and fairly monotonous, with a constant pitch just short of ouch. But the woods surrounding you are gorgeous. A little fog (which is likely) only adds to the atmosphere.
Go R onto Smith Grade, a thrilling mostly-down roller coaster through primordial Eden.
When Smith Grade dead-ends on Empire Grade, if that feels like enough for today you might be tempted to turn around and ride back, since the next leg is merely OK riding, but if you do this a) you will miss the glory that is Ice Cream Grade and b) you won’t save any work, because Smith Grade is a lot of climbing going the other way. So let’s push on.
Go L on Empire Grade. It’s feels pretty dull after Smith Grade—monotonously up, too wide to feel you’re “in” the trees, and fairly full of cars in a hurry. But it’s only 3 miles. At the intersection of Empire Grade and Ice Cream Grade and Felton Empire Rd. (yes, all three), you touch the Felton Empire/Empire Grade ride, which rides through the same intersection in the other direction.
At that intersection, go L onto the little jewel that is Ice Cream Grade. The first miles of ICG are as pretty as Santa Cruz gets, which is saying a lot. There isn’t much in there except forest, so you’ll have the place to yourself. You immediately drop down a sweet, serpentining descent to the creek, then climb back out a surprisingly easy grade up the other side until it dead-ends at Pine Flat Road. Go L and enjoy the rollicking descent down Pine Flat Rd./Bonny Doon to your car.
The loop is rideable in the other direction. It would add considerably to the climbing on Smith Grade and Ice Cream Grade.
Shortening the route: I’m torn about the best way to drop miles from this route. 1. You could skip the Bonny Doon lollipop stick and just ride the loop. 2. You could ride Bonny Doon/Smith Grade as an out-and-back. 3. You could ride Bonny Doon to the far end of Ice Cream as an out-and-back. Each has its merits.
Adding miles: Almost everything in any direction is good—see the Monterey Bay discussion in the Rides by Region chapter for a survey of roads in the Santa Cruz area. Since it’s the same conversation for all 6 of our Santa Cruz rides, I’ll do it once there and leave it at that.
