Have fun!!! In 2008 my wife and I were there stayed at Castle Lake camp ground. Great folks!! couple of things that I would suggest get the alpine loop map I think there available in Lake city where you purchase your permits the book packed full of information and the history of the different little ghost towns, also pack cold weather gear and rain gear, and a good camera awesome views. Although we were on utility quads the ride on a RZR will be great too, you will see a lot of jeeps on the trails as well. novice people who have never been off road before!! It was interesting to watch some of them city slickers!!! We rode from the CLCG all three days, and could of stayed longer we were there a week after Labor day Our first day we rode up to cinnamon pass 12,640 feet above sea level and there was snow on the mountain caps and over to Animas Forks we did get caught in a rain sleet & snow the storm came up behind us, what a surprise we also rode the Rio Grande, Grizzy gulch trail, silver creek traisl make sure you have plenty of fuel with you, there are no gas stations out there. Beautiful county. Would defiantly go back!!
