This is another must do ride up to the divide. Donât forget your camera. Some old roads and a RR grade not much singletrack but itâs still a classic MTB ride with some killer viewsâ¦
Follow FS 128 to Buck Creek about 3 miles . Watch for a road on the right with a FS gate turn right. Buck Creek is a steep climb up an old logging road. Towards the top you have an incredible view of the ski area and it flattens out a bit. Just as you crest a small hill follow the road to the left a short distance to Corona Pass/Rollins Pass Road turn right and enjoy the ride up the old RR grade. On your left you will see Broken Thumb this is the trail you want to take on your way down. Ride up the road 5 miles to the trestle. Rogers Pass Trail is on the south side of the road across from the trestle. Itâs a steep climb with lots of loose rocks. Once on top of the switchbacks it gets easier. Ride to the divide and take a few minutes to take it all in. Turn around and prepare yourself for exhilarating ride back down be sure and ride Broken Thumb on our way back. The first part of Broken Thumb is a gnarly rocky descent. The second half is a smooth cruise through the forest. Broken Thumb ends on FS 128 turn left and ride back to your vehicle.
From Idaho Springs take I-70 west to US 40 over Berthoud Pass to FS 128 (just past MM 234) turn right and park
