The United States has literally millions of acres set aside and designated as National Parks. These offer a wide variety of opportunities to enjoy the natural setting and people are able to commune with nature. Since they are located all over the United States there are many different terrains and natural features for visitors to enjoy.
Many of the National Parks have designated swimming. It may be a lake or a river that runs through the park. Many of them have natural springs. Besides swimming, many have ample room for other water sports like boating, canoeing and water skiing. They are usually stocked well for the fisherman.
Designated hiking trails are a common feature in our natural park system. They have mile markers and resting areas. Maps are usually supplied so that you can easily choose your route and enjoy the hike without losing your way. Depending on the location of the park there may be rock climbing or areas for rappelling.
Some parks close for the evening. But others have ample space designated for camping. Most have rugged areas for setting up a tent. Some also have more modern hookups for the use of travel trailers. And a few have areas with various sizes of cabins that are available to rent. These will be useful for you if you plan to have a safe time, instead of being out in the open.
Whether you enjoy the beach, mountains or forest there is probably a National Forest to meet your need for adventure. There are military parks and some which contain nature centers. These are useful educational tools for your family to enjoy when you are out in the open.
