Okay, then I still suggest the Canon City or Salida area. Both off of highway 50 and you would be rafting the Arkansas. There are tons of rafting companies and many different levels of difficulty.
It is really beautiful and can be quite relaxing when on the easier runs!!
There are some that offer camping along the area or, you can just find your own campgrounds along the way. You could visit the Royal Gorge and Buckskin Joes. There are many different things to do!!
I think you would just love it!!!
Google rafting companies in Canon City and you will come up with tons.
I like Raft Masters (hope I can say that)
