Strap on your big boy or girl pants for this one. You'll need them!
This trail gains elevation quite efficiently. The lower parts of the trail are pretty sweet and the upper reaches of the trail are characterized by steep grades and tons of loose grapefruit to football sized rocks. Tons of them! You can't avoid them and they will mess with you and throw you off your line. Then, they will probably laugh at you. I'm not sure about that last part, but I think I may have heard some snickering on my way bouncing down this mountain.
That all said, this trail provides access to some of the most beautiful country and views around northern Colorado. If you're looking to get some backcountry riding in through some pristine Colorado high country, this is a good option. Just remember those big boy/girl pants.
