Haystacks & Skulls
This is a 5 Star Route: highly curated, fully documented and a great ride!
This ride is the blend of two 5 Star routes: Haystack and Skull Hollow. Of the 3 routes (Haystack, Skull Hollow, and Haystacks & Skulls) this is Captain O’s favorite! Big views, fast riding pavement with little traffic, and some challenging gravel climbs.
For a complete take on the ride, please review the Haystack and Skull Hollow route descriptions along with the the ride details below.

Ride Details
Start in Terrebonne and follow the Skull Hollow route to mile 7.4, the right turn to McPheeters Turf farm. Instead, continue straight along the Culver highway tracking the Haystack route. Ride the dirt road segment through the Crooked River National Grassland, past Haystack reservoir, and then back on gravel and south towards Grey Butte. Begin climbing. Part way up the climb, just after the incredible views of the Cascade mountains, make a 90 degree left. You are now back onto the Skull Hollow route. Follow this to the summit, descend Skull Hollow, and then roll back on pavement towards Smith Rock and the start / finish.
Food / Water
None
Ride Notes
40 mm tires are more than sufficient for this ride.
Do not ride when wet. It looks like this could be the real sticky kind of mud, of the ‘hike a bike” variety.
We recommend the use of a red blinky light. Several roads have light to moderate traffic.
Ride Options
There are two shorter options to consider: Haystack and Skull Hollow. Haystack is the technically easier ride.

Riding great!! No mud, a few large puddles that can be ridden around.
Staff at Oliver Lemon’s market do not want non customers to park in their lot. They suggested the Park & Ride behind the Post Office. Should update the start description.
Thanks for the feedback. We have updated the start location to the Terrebonne Depot restaurant. Be sure to park in the back. And … be sure to get a burger and brew after the ride! Give back to those that make gravel cool!!
Riding really well right now. Great off season ride because there really is only the one steep climb and so much easy rolling pavement.
Riding well. This route could contain the hardest climb in co! 1 mile of 10% punctuated by 2, 20%+ grades! We altered the standard route to add some more scenery, miles, and climbing. https://ridewithgps.com/trips/58290330. Minimal sand, downhill into skull hollow is a bit rough. 40mm tires were sufficient.
It may have one of the steepest climbs in Central Oregon, but that depends how you define Central Oregon! :) There are some brutish climbs in the Ochocos and Oakridge has long, long, climbs sustained at over 10%. But … for us the most brutal climb is in Harts Mountain National Antelope Refuge. The first 4 miles of that is probably the most demanding climb in Oregon.
The route is riding great right now. Late April. No mud, a little bit of sand.
