Trail shared by Marty Spencer

Challenging singletrack with slickrock, sick descents and a killer view from the top.

Features -none-


Big Rock trail is a 'must do' trail for the serious mountain biker. Going up is an aerobic challenge and coming down gets pretty technical in places so this is not a beginner friendly trail.

KEEP OFF THE MOSS ON THE SLICKROCK!!! It is easily damaged and takes years to recover.

The trail is a mostly steep singletrack over a variety of surfaces ranging from hard pack dirt to loose stones to slick rock. Though only .84 miles in length, this trail will make you work to get to the top. Once there you have only three options for the decent. Big Rock Trail will get you closer to the Corn Mill Shoals Access Area parking lot. Or take either leg of Cedar Rock Trail: the right leg is more technical but shorter than the left leg.

Once at the top you'll find great views of the surrounding area. The top of Cedar Rock has 'balds' - large expanses of slick rock. Please stay off the plants since most of them are easily damaged and very slow to recover.

The rocky surface of the balds makes placing trail markers difficult so you'll see several cairns or rock piles marking the trail here. Try not to knock them over and feel free to rebuild them if you come upon one that someone else disturbed.

This is a must-do trail if you're riding in DuPont. Like the description says, you have to pay the price to get to the top but the descent (though less than a mile) is worth it if you want to experience a nice mix of slick rock & tech. I slo strongly recommend riding Burnt Mtn trail (clockwise) if you're riding from the Corn Mill Shoals trailhead. Apr 12, 2018

Lots of fun, I would imagine as close as you're going to get to Slickrock and stay on east of the Rockies (yes, I have done Slickrock). Some technical spots for sure but they're pretty easy to spot. A little tricky to see the start, when you get to the sign on top of the mountain you need to bear right and then do almost a complete 180 to get on the trail. To avoid unnecessary road time do Burnt Mtn, climb to top and do Cedar, climb back to top and do Big Rock and you'll end up right back at Corn Mill Shoals parking. Just a guess that would be a little less than 10 miles, that should leave you enough gas to go have some fun on Ridgeline and Hickory (I drive to the other parking area) Oct 15, 2018
