I'm kind of near there. (Fort Collins) There are some amazing road rides in the area, east, west, south mostly. If you are in Estes there is some up and a lot of downhills that you then have to ride back up. You could log some epic days.

RMNP Very beautiful place. It is best enjoyed for the hiking. No mountain bikes allowed in the park on trails, but roads ok, of course.

Enjoy it. You won't be alone.
