If you love adventure and natural scenery, then road-tripping across the country might be the perfect getaway opportunity for you and your family. With 50 states at your disposal, you can find and select the perfect attractions that everyone in the family will enjoy and look forward to.
Especially if your family loves camping, you can consider staying in one of the many state or national parks located across the country. Many parks offer spaces where your family can park your RV or pitch a tent for the night while offering unforgettable attractions for you to explore during the day.
State Vs. National Parks
If you are searching for the largest parks in the U.S., you may find two different kinds of parks — state and national. The difference between the two depends on who manages and maintains the parks. State governments and parks and recreation programs will oversee state parks, while federal parks programs protect national parks. If you are specifically searching for the biggest state parks in the U.S., you will want to ensure state governments run them.

1. Alaska National Parks
If you are wondering in which state is the largest U.S. national park, the answer is Alaska. The Last Frontier state boasts seven of the top ten largest national parks in the U.S. With wide areas of land available and several ecosystems and scenic landscapes covering the state, Alaska has eight total national parks you can visit, ranking just below California for the total number of national parks.
Alaska's largest national park, Wrangell-St. Elias, protects around 13.2 million acres of land, which is bigger than some countries and several other U.S. national parks. Several parts of this vast wilderness are still untouched by people and include several wilderness types, from mountain ranges to glaciers to active volcanoes. Further, this national park is home to the largest peak in the United States, Mt. Saint Elias, reaching just over 18,000 feet.
Some of Alaska's top national parks include:
- Gates of the Arctic: This park is within the Arctic circle, making it the most northbound American national park. However, you can only access this park on foot because there are no roads, so be sure to research the area before making the trek thoroughly.
- Denali: Denali is one of Alaska's more popular national parks. When exploring, you can come across many types of Alaskan wildlife, including bears, elk, moose and caribou. Further, it is home to Mt. Denali, the highest peak in all of North America, which rises over 20 thousand feet.

- Lake Clark: You can only access this national park by plane or boat, but it may be worth the trip for you and your family. This park includes several mountain ranges and active volcanoes. Further, because of its more remote location, it is less popular with tourists, allowing you to have a peaceful park visit where you can truly appreciate nature.
- Kobuk Valley: Like Lake Clark, Kobuk Valley National Park is more remote and receives fewer visitors each year than Alaska's other parks. However, it can be a great place to visit if you want to witness caribou in the wilderness.
