Whether its Pagosa, South Fork, Creede, Lake City, Ouray, Silverton or Durango; its not the towns that are special, its the large unspoiled, lightly used high country wilderness areas that those towns surround.
If your interested in hiking, off road exploring and natural beauty, you won't find it on the cities web site. Try the Rio Grande and San Juan National Forest sites.
I've been exploring this large area by foot, Jeep and ATV, every summer for 6 years and have barely touched the surface. I alternate which city I stay at every couple weeks, just for variety. The town & campground I use that week is just a place to park. What keeps bringing me back are not the cities, but the hundreds of high country hiking trails, high country lakes and streams full of trout, and hundreds of miles of Jeep or ATV trails into some of the most beautiful scenery & lightly used trails in Colorado. Most days, once I leave the trailhead I don't see more than 1 or 2 people or vehicles all day long, except for Holiday weekends if I don't get far enough into the back country. What I do see are deer, elk, moose, beaver, black bear, big horned sheep, mountain lion, lynx, and lots of hungry trout on my line.
