I don't know about hiking but driving through Roosevelt Nation Forest and driving through Estes Park was fun for us. The Denver, Boulder, Longmont, Fort Collins areas have a great Craft Beer Scene if you are into that. ( thats what we go for) Some of the breweries are pretty nice. There is a place out toward Glenwood Springs that has a train ride. Its not the greatest train ride that we have taken but I don't regret taking the time to do it. We go in October but in the Spring and Summer there are rafting opportunities.
