Re: In need of Colorado trip suggestions!!
Another possibility is the Big Thompson River which flows east from Estes Park. Estes Park is the east entrance to Rocky Mtn NP. Also just north of Ft Collins is the Poudre River and there are numerous campsites along the river and a few folks on this forum that fish both rivers.
Don't forget to use the search function on the forum, it can turn up some good info.
