America is full of beautiful national parks and nature reserves. You've probably visited some of the most popular ones like the Yosemite, Grand Canyon and Yellowstone, but there are actually more than 50 national parks in the US, and some of them are really under-appreciated. Let's take a break from the populous, popular parks and take a look at some of the best underrated national parks in America. Here are some of them:

Great Basin National Park, Nevada. It's actually surprising how this place is underrated considering it's one of the most picturesque destinations in the US. Great Basin has all the things you're looking for--- magnificent views, luscious wildlife, beautiful caves, towering mountains, and it is also one of the best stargazing spots in America. Don't miss out.

Wrangell-St. Elias National Park and Preserve, Alaska. You'll never run out of heart-stopping and thrill-seeking adventures here at Wrangell-St. Elias National Park. It is the largest national park in the United States, and several adventure tours are always offered here. I guess we can understand why the conservatives prefer more the Denali National Park, but if you're a total badass adventurer, experience St. Elias National Park too.

Biscayne National Park, Florida. This national park is somewhat different from the rest, seeing that almost ¾ of the whole preserve is set underwater. Biscayne National Park houses the third largest coral reef in the world, and you can experience scuba diving and swimming with over 200 species of colorful fishes and other marine animals. The beauty of this place will make you feel like you're on a deserted island in the Caribbean, so don your diving gear and take selfies under the ocean!

Wind Cave National Park, South Dakota. Wind Cave National Park is a good alternative if you can't afford to go to the world-famous Underground River in the Philippines, and after your visit I'm sure you'll be wanting to come back. It houses the 4th largest cave in the world, and with the ranger-guided tours always available, you will be mesmerized with its display of boxwork, the unusual formation of thin calcite fins resembling honeycombs. Outside, you'll be rewarded with a diverse wildlife and an impressive green scenery as well.
