well theres always estes park thats a nice area, or head up to eldora to camp up on 4th of july road, or i like to just road trip around northern colorado sometimes, lots of cool calm relfective backroads there. Theres also a lot of nice quaint towns around there to just relax in. theres also areas around coal creek canyon that are nice. Depends on your perogative. hope that helps, even if the responses are late. if not let me know, ill see what other areas i can conjur up.
Depending on what your look for....
Gold Lake in Ward (I think)...it is located on a lake with rustic cabins, hot springs and a great place for dinner. Great for solitude and relaxation. Great couples place.
