It's difficult to balance access with conservation. I don't feel that limiting access is the right approach on its own. There's clearly a demand for visiting scenic parks, and why would I have more of a right to visit than anyone else? And seeing natural beauty is important for valuing natural beauty. As others have pointed out, it's mostly the main sites in a handful of parks that are overrun. I think it's unfortunate to effectively sacrifice some of the most beautiful parts of the country, but it might still be a fair tradeoff.
There are room for improvements, though. For one, I think parks could have strict enforcement and fines for littering. Second, driving into a park usually means wasting a lot of time getting through the entrance station and finding somewhere to park. Post-COVID, I wish parks would provide better public transit into and within a park so driving isn't as necessary. Similarly, I wish they would set a cap on daily car entrances and let you purchase admission online beforehand.
