Taylor Park is probably the "Premier" riding area in Colorado (although one could say that about most of our state :) )
It is located north of Crested Butte and west of Buena Vista. Probably 300+ miles of trails, some easy some "hard as you want it to be"
Lots of single track, (lots already ruined by a t v s) :whiner:
As far as HS in the area, I don't know of any, heck there are only two series near Denver (where 75% of the people live) so I don't know of any in your area.
I would contact these guys
www.cbtrailriders.org they will have more information
