Cottonwood pass is not that bad, typical dirt road, some washboard, I wouldn't be afraid of taking a pop-up. We usually stay at the cabins around the trading post, either Holts, or right at the trading post, I have contact info if your interested. The USFS campgrounds will be closed in October however there is alot of open camping off of Italian creek road. I would also watch out for hunting season, I like to stay out of the woods when drunk guys are driving around on ATVs shooting at stuff. The trading post folks are very friendly, and there is gas and food there. Just get up REAL early Saturday and make the trip, I assure you it will be worth it!
