Fall is one of our favorite times to visit Colorado, and Buena Vista is one of our favorite places to base. We usually include trips over Cottonwood Pass into Taylor basin and up to Crested Butte as well as over Independence Pass into Aspen (without the fifth-wheel, of course.)
We have many collections of photos on web pages, but maybe this one will encourage your visit. On this trip we were staying at the Arrowhead RV Park, a few miles north of Buena Vista. These photos are greatly reduced in resolution for uploading to the web.
