4J in Ouray or the KOA on the north edge of town. If u decide to explore some of the 4x4 trails, and you should, get trail info at any of the Jeep rental places. Stay OFF the Black Bear trail that goes from 550 over to Teluride!!! Experienced 'Wheelers' have died on that trail! Be sure to ride the steam train out of Silverton! If u'r driving up from Durango on 550 be ready for some scary places between Silverton & Ouray. In a few spots there is NO ROOM to install a guard rail. Just the roadway, the white line & the ravine. We now go further west to Delores and up 145 past Teluride and over to 550 at Ridgeway. If all is full at Ouray or Silverton, there is a wonderful state park north of Ridgeway called Ridgeway. While in the area you should REALLY camp at and tour Black Canyon of the Gunnison Nat'l park.
