We used to spend a couple of weeks every year camping, 4 wheeling, hiking and "condo-ing" in the Durango, Silverton, Ouray and Tellruide areas, sometimes ranging over to Crested Butte, Montrose and Gunnison. It looks like BeanMan has the intel on the snowpack, which would have been a major concern of mine in June. The Million Dollar Highway between Silveron and Ouray is really pretty. We really like Ouray, and if we won the lottery (without ever having bought a ticket), we would have a place there.
Everything may seem like its close to the 4 corners area, but the distances are more than you think and mountain driving can be slow even for short hauls. Don't try to see everything. The train trip alone would be an entire day. Some 4x4 routes are a good chunk of a day. The Grand Canyon and Mesa Verde ain't exactly drive-bys. Pick out a few things and savor them. Some solitude on a hiking trail can be a lot more fun than being jammed up in traffic in Durango or a national park. You will be back, so don't try to see it all.
