The trail is mostly an out and back with a loop at the end. When at the top, stop to check out the view and prepare for a fast rollercoaster ride of a downhill that will peg out the fun-factor meter. Then a short climb leading to a more technical but fun downhill. I'll give it a 4 because it's a little on the short and over used side, but not like those closer to denver. Straight up Bitterbrush, and then left at the Nelson loop back down to the parking lot.
Some parts are really easy and other parts are really hard with really technical sections.
Steep climbs and the loop is fun at the top. I would recommend it to anyone. If you are a cross country rider the whole loop is great if you are a DH biker ride up the first little part of technical turrain and turn around at the top and go right back down. This trail is pretty easy without any real hard climbs except the few rocks on the climb to the first apex. Fast and rolling.
