Check munqe chick or my forum history for posts in US/ overseas riding threads, have posted loads of pics of CO including monarch crest, CB and WP. Laptop dead so struggling to post photobucket stuff via phone. winter park a real treat, think lift assisted XC singletrack rather than gung ho alpine DH, even their black runs make the most of the terrain.
We did it in July, all the trails clear, hot in boulder etc but not too hot to ride in mountains (though most of our riding hols have been in places where its high 20Cs so we have become accustomed to big camelbacks and factor 30...)
In CB 401 trail, 403 trail are classics. Monarch crest is a name for a stretch of continental divide trail, the towns either side provide uplifts. Buffalo Creek amazing, I was expecting a twee scenic ride from the name but it is like Moab with trees and boulders. Possibly my favourite ride in CO as it exceeded expectations.
