8 National Parks You Can Visit Last-Minute, Without Reservations in 2023

Because one more summer adventure is always a great idea.

We love a last-minute road trip, especially to pristine, protected areas like national parks. But with parks being so busy these days, many high-trafficked destinations have implemented reservation systems that require a timed-entry permit to visit. Even if you plan ahead, these reservation tickets can be hard to score for places like Arches, Acadia, Glacier, Rocky Mountain, Haleakala, or Zion.

To be fair, the reservation system is, for the most part, a good thing. It helps control some of the most overcrowded areas, maintain visitor safety, and help protect wildlife, natural and cultural resources.

And while they might not be ideal for the non-planning types among us, there are still plenty of national parks to visit that also offer jaw-dropping views and picture-perfect moments, without the crazy crowds.
