Update 2021: Greenville was destroyed by fire in the summer of 2021. The fire stopped at the eastern edge of town and left the first 22 miles of this ride pristine (thanks, Robert).  The 10-mile climb to Antelope Lake is presently (9/24) being repaved and is what appears to be good dirt (see details below.)

There are more awe-inspiring rides, but there is no prettier ride in California than this one.  It’s a short form of the Indian Valley Century.   It goes along the lip of two flat, postcard-perfect valleys framed by mountains (with snowy peaks, if you time it right), and you’re just a bit up off the valley floor, so you get all the scenery without the flat—the road gently bobs and weaves and rises and drops and thus provides you with a delightfully varied road contour.  Then the outward leg ends with a ten-mile climb that’s entirely doable and parallels a tumbling, rocky creek.  I’ve cut off two loops from the century route I don’t need, but I’ll tell you they’re there and what you’re missing.   All the significant climbing is in the last 10 miles out, so if you skip it the ride is easy.

I rarely talk about driving routes to rides, but this one merits a word.  As of 9/24, the two main routes to Greenville—up Hwy 32 through Chester and up Hwy 70 through the Feather River Canyon—are problematic.  Hwy 32 is essentially closed while they deal with repairs from the Park Fire.  Cars are allowed through at 3 designated times each day.  Consult the CA road conditions website.  Hwy 70, while a beautifully scenic drive, is undergoing a lot of construction, resulting in numerous one-way stretches and traffic hold-ups.  When I drove it I counted 7 time-consuming stops, the longest being c. 15 min.  None of these construction projects looked anywhere near completion.  Plan your travel time accordingly.

Greenville has ample shoulder parking.  If school isn’t in session I park in the school parking lot (unmissable as you enter town on your R coming from the south).  Ride north and east out of town on the only road, North Valley Rd.  Ride 34 miles on this road, then turn around and ride back.  Keep going on North Valley Rd., ignoring a few roads going off to the left and right, as the road name changes to Genessee Rd, then Indian Creek Rd., heading first to Genessee Valley and finally to Antelope Lake.

There’s only one place to get lost. At 9.5 miles in, there’s a fork.  Diamond Mt. Road takes off to the L (signed), and our road, which is oddly unsigned, goes R and immediately crosses a small but sturdy bridge.

Between Indian Valley and Genessee Valley there are a few miles of lovely woods, and here you get a mild climb and descent—if you skip the climb to the lake, this is the only noticeable climb on the ride.

Ride through Genessee Valley.  Midway you pass the Genessee store and restaurant, which may or may not be open. I had a long conversation with a local in Spanish which implied that it was indeed open, sometimes, in some seasons.  If it’s open, check it out.

At the end of the valley the big, obvious climb starts.  A mile before it kicks in, you pass a sign reading “Road closed 1 mile.”  A mile later the construction starts and the road turns to what looks like excellent dirt (as of 9/24), but there is no gate or warning sign scaring you off.  I didn’t explore further.  If you attempt it, it’s an honest 10 miles up.  After a mile or so you’ll say, “I don’t think I can do this for 10 miles,” but all the steep is in the first 3 miles; then it mellows out and rolls so much that you’ll do some work coming back “down.”

At the dam the road circumnavigates the lake, but I don’t like the ride because I think it’s ugly.  The area was burned to ash many years ago, and the soil is a chalky moondust that won’t allow much to grow back.   Do it if you’re set on riding a hundred miles.  Otherwise, turn around and ride home.

At the bottom of the climb, return the way you came, unless you dislike out and backs, in which case see below.

Shortening the ride: Skip the climb to Antelope Lake.

Adding miles: To restore the miles I cut from the Century, a) ride around Antelope Lake (see above) and b) take the big loop that goes off from North Valley Road to the northeast.  It’s Diamond Rd. going out and North Arm Rd. returning if you ride it on your way out.  You’ll need to ride it twice, on your way out and your way home, to total 100 miles.  It’s perfectly pleasant but a notch less scenic than the valley riding.  You might consider riding it once, on the way out or the way back.

About halfway out along the main route there’s a 1-mile detour to the tiny, cute town of Taylorsville, which has a market, a tavern, and a church (see Johnmc’s comments below).  It’s worth it if you like tiny, cute towns.

If you’re dead set on riding a loop, stay left when you re-enter Indian Valley, ride through Taylorsville, and continue west to Hwy 89 on a much flatter, straighter, and less rewarding valley road.  This will necessitate you riding a final leg up Hwy 89 to your car, managing one significant climb and descent in the process, but it’s a pleasant ride for a highway.  There are other roads through the heart of Indian Valley, smaller and even more boring, if you like flat.

Reachable by car are 1) our Chester Back Roads rides, and 2) a challenging and rewarding ride from Quincy up Rd 119/414 to Buck’s Lake.  You can make this ride a lollipop by taking the south route to Buck’s Lake out and the north route home when you hit the obvious fork.   Buck’s is a lovely lake with rustic resorts, cabins, and a road along its west shore for more riding.

Afterthoughts: Time of year matters here.  The valleys are at their prettiest in the spring, before things turn hot.  But you’re in the mountains, and spring snows and hailstorms are common.   I’ve done the century once in snow and once in hail, and both times I froze.  Ideally you’ll do this ride before the summer heat arrives but while there is still picturesque snow on the mountain peaks.   Watch the weather report and take an extra layer, especially if you’re planning on doing the Antelope Lake loop.
