I would not recommend it to small and tight. I was told their is camp group past the falls though be never been. They might have some where to turn around but the falls no. Very windy narrow road
If it's a smaller one it is possible. I would err on the side of caution though. The road is not more than 1 lane each way and there is not even enough of a shoulder for a car to turn around comfortably. A larger vehicle would be reliant on side rest stops, scenic view points, and recreational areas. You could end up driving out of the way a considerable distance before being able to turn around or possibly even get stuck. Is it possible yes but I wouldn't recommend it.
I would not recommend it. The road is narrow and crooked. Parking at the falls would also be a problem.
I wouldn't recommend a large rig drive through the area, but smaller rigs should be okay although the parking is limited and the roads narrow.
