Stayed at Riverside RV resort about 14 miles north of Durango off CO 550 for 6 nights mid summer. We opted for the "pricey" riverside site and loved the site/view out the back window. Nice park, amenities and well run but the sites are tight. We took a 4 wheel tour above Silverton one morning and took the afternoon train back to Durango. If you have the budget for it I recommend both. Mesa Verde was well worth the drive. The drive to Ouray and visit to the town is a nice day trip too. We have friends in Farmington which is 50 minutes south of Durango and they took us to the Aztec NM ruins. You can actually walk through much of the ruins there. Monument Valley is probably about a 2-1/2-3 hour drive from Durango in toad so do that if you can. We'll be back as the 4 corners area has lots to offer.
