Review: Fun trail with some decent climbs and descents. Trail is in rough shape and not maintained. This made for a much slower trip and some sections were near impassable

Review: Did this loop around the lake with my wife and dog on our mountain bikes. It was scenic and moderate in difficulty. I did just come from sea level so that made it more challenging. Not technical but worth it if you are in the areas.

Review: I've heard that trail 40L is impassable to Centennial trail. Forest service has not done trail maintenance. Check Local Bike Shops for my info.
