Betasso Preserve / Boulder, CO

~Betasso is a quick smooth loop through forested hills, with plenty of tight turns and speedy downhill sections. The climbs and descents alternate enough to allow even a beginner to have a good time on this track. In some places the trail is cut right into the side of the mountain, so you are looking at a serious drop off if you're not paying attention. The trail has some nice views and is well maintained.
