I've been to all 63 US national parks. These 4 are my favorites — but these 3 didn't impress me much.

After visiting all the national parks in the US, I have favorites and a few I'm in no rush to return to.

One of the top things travelers love to do when they visit the United States is embark on a great American road trip, filled with stunning national parks.From Yellowstone's thundering herds of bison to Yosemite's towering granite walls, there's no shortage of natural wonders inside the millions of acres of American parkland.Of course, with 63 different parks to visit, it's inevitable that some won't be a slam dunk for every single visitor.I spent the entirety of 2020 visiting every US national park, and although most were absolutely spellbinding, there are several that I won't be rushing back to anytime soon.Below, I'll get into four of my all-time favorites — plus three let-downs that some travelers might want to skip.

I truly fell in love with Grand Teton National Park.

The landscapes in Grand Teton National Park are incredible.
