Review: There are a lot of reasons to ride this trail. No, it is not a pure singletrack trail. There is doubletrack and 4x4 trail but there is also some very sweet, flowy singletrack to enjoy. The scenery is epic (as my kids would say) and I made multiple stops along the trail to enjoy it. There are some sandy sections and steep rocky hills that might require you to dismount but overall, this was a great ride. You start off descending (which means you'll end up with a big climb to finish, ugh!) and at the bottom you ride along the North St. Vrain Creek for awhile before the trail takes you up a valley for several miles. You can turn around at any point and head back. There wasn't much traffic on the trail (a few hikers and one other mountain biker who was also fly fishing and provided some friendly directions to me).

Review: It was a fun descent to the doubletrack. It is possible to turn it into loop. Just take a right once you hit the the double track. Then you follow the river upstream until you hit the lake (more of a puddle) where you keep going up. The climb to that point has loose rock but manageable. After that it is a climb from hell. I had to push my bike up, cause there was no way I could make it up. It was not fun, kept sliding down and the climb was pretty long, at least it felt like a lifetime. Once on top, you hit a fire road (4x4 road) keep taking a right and you'll end up in the parking lot. I would recommend doing it CCW and starting the climb with the fire road first and maybe it would be lot more enjoyable, but be prepared for hell of a decline!
