Hi there! I personally wouldn’t recommend. Even if you’re able to navigate the switchbacks on the one lane loop road up.... very few sites will accommodate a rig that long. We saw nothing longer than about 20-25 feet make the journey into the campground.

If you’re a good driver it works but the road is winding and tight. So you might be able to enter Aguirre with a 35’ RV.

Yes, however your choice of sites may be limited to roadside sites, most of the sites tend to be tight.
