Gemini Bridges Road, trail head at 191-ends at 313. A little spooky at the start but I did it in a four door one ton truck. There is a small campground on the south side where you can walk/climb on the smooth rock. I dont remeber the name but there is a rock formation at the back that looks like an owl. It's near goony bird rock iirc.
La Sal Mountains. This pic was in late October and the Aspen/poplar were spectacular, your season may vary.
