The best section of Trail to Ride is between Rammell Mtn. Rd. 267 and the North route road of Jackpine-Pinochle Loop Rd. 266. This ride also crosses the South Route of Jackpine-Pinochle Loop Rd. 266 which is where we begin many rides on 012 to the North end.
The section between Dry Ridge Rd. and Rammell Mtn. Rd. is in place BUT, has seen the least amount of trail work with downed timber and overgrowth. This section is not recommended to ride unless you like your bike on the shoulder 75% of the time.

Ride it from Rammel Mtn Road North to the end. It was good, a bit overgrown in early July in some spots. Most of it is very easy but there are a few steep descents with some technical sections definitely making it a black. Blue trail riders could ride this but use caution as you will need to hike a bike. There are lots of steep uphills back out of canyons which required some serious pedaling and in some cases hike a bike.
We hope you've been enjoying Trailforks!
