Did you know there are over 10,000 State Parks across the United States? Families don’t have to go too far to explore the great outdoors and make lasting memories.

While we love National Parks, a plus to State parks is that they tend to be less crowded and more affordable. They also offer a wide range of family activities, including hiking, swimming, fishing, camping, and boating. Many parks also have playgrounds, picnic areas, and ranger-led programs. Some parks offer additional amenities such as cabins, lodges, and restaurants.

Here are our picks for the 10 best state parks in the U.S. for a great family vacation adventure, where you’ll find everything from wild horses to waterfalls and buffalo roundups to a natural slip and slide.
