The road is narrow but it’s open so you can see someone coming up the road. The spots (and there’s only 2-3) are not huge and you don’t want to get too close to the cliff itself. A park ranger told us we had to be 1.5 car lengths from the road. That would be tough to do in a bigger rig. I wouldn’t suggest anything more than 24’ motorhome and a definite NO to trailers of any size.
