There are three different types of camping opportunities in the USA. Recreational Camping for people who want all the comforts of home, primitive camping for those who enjoy closer contact with nature and wilderness camping for the more adventuresome. You can find wide ranges of camping facilities all across the US in each of these categories. Recreational camping is available in thousands of commercial campgrounds across the USA. Most of these facilities include clean toilets, hot showers, laundry facilities and convenience stores. Primitive camping facilities are located at the national parks, state parks, local parks and government recreational areas across the US. They normally have campsites with picnic tables, toilets and a supply of drinking water. A few of them may include showers, but they normally do not supply electric or water hookup. Some are located along hiking trails far from the nearest road. You do not see many trailers or mobile homes at primitive campgrounds. Most tent campers prefer these types of facilities. Wilderness camping is permitted in many national parks, state parks and designated wilderness areas. Usually, no camping facilities are provided, but you are allowed to camp anywhere. In some areas, you may be required to camp only at designated campsites. You must take all of your water and food and shelter in your backpack or on a pack animal. Most of the parks require you to register or obtain a camping permit before entering the wilderness.
