Bonny Doon Road/Empire Grade

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 rainforest.  Bonny 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 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 a steady, fairly steep pitch just short of ouch (as are a lot of the roads in the area), but it’s so beautiful you’ll be immune to all negative thoughts.  When Bonny Doon forks into Smith Grade and Pine Flat Rd, go R onto Smith Grade, a thrilling 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 poor 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 not great—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.  And we need it to get to a little wonder: Ice Cream Grade, on your L.  The first miles of ICG get my vote for prettiest stretch of road in the Santa Cruz area.  Which is saying a lot.  Feel free to quibble.  But it’s inarguably beautiful.  Far too soon, it dead-ends at Pine Flat Road.  Go L and enjoy the excellent descent down Bonny Doon to your car.

The loop is totally rideable in the other direction.  It would turn the 3 miles on Empire Grade into a fast, straightforward downhill and thus get it over with more quickly, but it would add considerably to the work load on Smith Grade.

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 4 of our Santa Cruz rides, I’ll do it once there and leave it at that.

    I just found your website and am extremely impressed.

    I live on this route, and commute to UC Santa Cruz using the circular part of the “lollipop.” I always go in the clockwise direction, i.e., East on Ice Cream Grade, and then South (downhill) on Empire Grade, and I come back on Smith Grade and Bonny Doon Road. I recommend doing so because climbing on Empire Grade involves a lot of traffic coming fast up the hill around blind corners, whereas climbing Smith Grade breaks up the climbing and the road is almost always car-free. I do this for survival, but I believe the climb is much more scenic and enjoyable that way. Also, when climbing, one can (at the expense of adding another mile or so) turn left at the Winery (as does Bonny Doon Road), and then drop back to Ice Cream Grade via a very short stretch of Pine Flat. Another variant is to go up Martin Road, and you will see unusual sandstone cliffs and the results of a 2007 forest fire. Finally, those who need more of a challenge will enjoy going uphill on Pine “Flat” to Empire Grade, and then continuing all the way out to the gate at Lockheed.

      Just got back from riding that Bonny Doon ride. Really glad that I saw your suggestion about going clockwise. Traffic was as you predicted. Very light going up the smith grade. Beautiful ride but tough for an old guy. Much respect for anyone who rides that regularly. Thanks for the tip!
