Camping is an outdoor activity involving overnight stays away from home with or without a shelter, such as a tent or a recreational vehicle. Typically participants leave developed areas to spend time outdoors in more natural ones in pursuit of activities providing them enjoyment. The night (or more) spent outdoors distinguishes camping from day-tripping, picnicking, and other similarly short-term recreational activities.[ citation needed]
Camping as a recreational activity became popular among elites in the early 20th century. With time, it grew in popularity among other socioeconomic classes. Modern campers frequent publicly owned natural resources such as national and state parks, wilderness areas, and commercial campgrounds. Camping is a key part of many youth organizations around the world, such as Scouting, which use it to teach both self-reliance and teamwork.
Camping describes a range of activities and approaches to outdoor accommodation. Survivalist campers set off with as little as possible to get by, whereas recreational vehicle travelers arrive equipped with their own electricity, heat, and patio furniture. Camping may be combined with hiking, as in backpacking, and is often enjoyed in conjunction with other outdoor activities such as canoeing, climbing, fishing, and hunting. Fastpacking involves both running and camping.
There is no universally held definition of what is and what is not camping. Just as with motels, which serve both recreational and business guests, the same campground may serve recreational campers, migrant workers, and homeless at the same time. Fundamentally, it reflects a combination of intent and the nature of activities involved. A children's summer camp with dining hall meals and bunkhouse accommodations may have "camp" in its name but fails to reflect the spirit and form of "camping" as it is broadly understood. Similarly, a homeless person's lifestyle may involve many common camping activities, such as sleeping out and preparing meals over a fire, but fails to reflect the elective nature and pursuit of spirit rejuvenation that are integral aspect of camping. Likewise, cultures with itinerant lifestyles or lack of permanent dwellings cannot be said to be "camping", it is just their way of life.
The examples and perspective in this article deal primarily with the United Kingdom and do not represent a worldwide view of the subject. (October 2013)
The history of recreational camping is often traced back to Thomas Hiram Holding, a British travelling tailor, but it was actually first popularised in the UK on the river Thames. By the 1880s large numbers of visitors took part in the pastime, which was connected to the late Victorian craze for pleasure boating. The early camping equipment was very heavy, so it was convenient to transport it by boat or to use craft that converted into tents.  Although Thomas Hiram Holding is often seen as the father of modern camping in the UK, he was responsible for popularising a different type of camping in the early twentieth century. He experienced the activity in the wild from his youth, when he had spent much time with his parents traveling across the American prairies. Later he embarked on a cycling and camping tour with some friends across Ireland.  His book on his Ireland experience, Cycle and Camp in Connemara led to the formation of the first camping group in 1901, the Association of Cycle Campers, later to become the Camping and Caravanning Club.  He wrote The Campers Handbook in 1908, so that he could share his enthusiasm for the great outdoors with the world. 
Possibly the first commercial camping ground in the world was Cunningham's camp, near Douglas, Isle of Man, which opened in 1894. In 1906 the Association of Cycle Campers opened its first own camping site, in Weybridge. By that time the organization had several hundred members. In 1910 the Association was merged into the National Camping Club. Although WW1 was responsible for a certain hiatus in camping activity, the association received a new lease of life after the war when Sir Robert Baden-Powell (founder of the Boy Scouts movement) became its president.
The International Federation of Camping Clubs (Federation Internationale de Camping et de Caravanning) was founded in 1932 with national clubs from all over the world affiliating with it. By the 1960s camping had become an established family holiday standard and today camp sites are ubiquitous across Europe and North America.
Camping is also labeled by lifestyle: Glamping (glamorous camping) combines camping with the luxury and amenities of a home or hotel,  and has its roots are in the early 1900s European and American safaris in Africa. Workamping allows campers to trade their labor variously for discounts on campsite fees, campground utilities, and even some degree of pay. Migrant camps are formed not for recreation, but as a temporary housing arrangement. Campgrounds for custom harvesters in the United States may include room to park combines and other large farm equipment.
Another way of describing camping is by the manner of arrangement: reservation camping vs. drop camping. Campgrounds may require campers to check in with an employee or campground host prior to setting up camp, or they may allow "drop camping," where this is not required. Drop-in campsites may be free or a drop-box may be provided to accept payments on the honor system. Although drop camping is often specifically allowed by law, it may also exist in a legal grey area, such as at California's Slab City.  Social media-oriented towards drop camping provides information on recent police enforcement, campsite quality, cost, and length-of-stay requirements.

The equipment used in camping varies with by intended activity. For instance, in survival camping the equipment consists of small items which have the purpose of helping the camper in providing food, heat and safety. The equipment used in this type of camping must be lightweight and it is restricted to the mandatory items. Other types of camping such as winter camping involve having specially designed equipment in terms of tents or clothing which is strong enough to protect the camper's body from the wind and cold.
Survival camping involves certain items that campers are recommended to have with them in case something goes wrong and they need to be rescued. A survival kit includes mandatory items which are small and must fit in one's pocket or which otherwise could be carried on one's person. This kit is useless in these circumstances if it is kept in the backpack that is left in camp. Such a kit should include a small metal container which can be used to heat water over a campfire, a small length of duct tape which can prove useful in many situations, and an emergency space blanket. These blankets are specially designed to occupy minimal space and are perfect for making emergency shelters, keeping the camper warm. Also because of the aluminum-like color this blanket is reflective which means it can be easily seen from an aircraft. Candle stubs are good in starting a fire as well as in warming an enclosed space. One or two band-aids are mandatory in this type of camping. Any camper, and not only the survival ones, need waterproof matches or a lighter and a large safety pin or fish hook which can be used in fishing. Rubber gloves, antiseptic wipes, tinfoil, jackknife, or halazone tablets (which purify the water) are also to be included into a survival kit. Although these seem too many items to be carried on one person, they are in fact small, lightweight and definitely useful.
Winter camping can be dangerous without respecting the basic rules when it comes to this particular activity.
- Firstly, the cold is protected against with clothing of three types of layers as follows: a liner layer against the camper's skin (longjohns), an insulation layer (fleece), and a water- and wind-proof outer shell.  Although cotton is one of the best quality fabrics there is, it is not recommended to be worn on winter camping because if it gets wet it dries out very slowly and the wearer could freeze. Rather than cotton, winter campers should wear wool or synthetic materials. The boots must be waterproof and the head must be protected against the cold. Although it seems a good choice, campers are advised not to wear too many pairs of socks as they might restrict blood flow to the feet, resulting in cold feet. Gaiters should also be worn to avoid snow and rain wetting the boots.
- Secondly, one should include carbohydrates into their diet to keep their body warm as well as to provide energy. Hydration is very important so winter campers should drink plenty of water to keep themselves well hydrated, noting that water stores must be kept from freezing.
- Thirdly, the tent must be carefully chosen to shelter it from the wind.
The following is a list of commonly used camping equipment:
- First aid kit
- Tent, lean-to, or other form of shelter
- Hammer or mallet to drive tent stakes into the soil (hammer are often a claw hammer, which is also helpful for removing them)
- Sleeping bag and/or blankets for warmth
- Sleeping pad or air mattress to be placed underneath the sleeping bag for cushioning from stones and twigs, as well as for insulation from the ground
- Lantern or flashlight
- Hatchet, axe or saw for cutting firewood for a campfire
- Fire starter for starting a campfire
- Folding chairs for placement around a campfire
- Ropes for stringing clothes line and for securing the shelter
- Tarp for adding an additional layer of storm protection to a tent, and to shelter dining areas
- Raincoat or poncho
- Hiking boots
- Fishing pole
- Canteen (bottle)
- Chuck box to hold camp kitchen items for food preparation, consumption, and cleanup
- Trash bags, for the handling of waste; see leave no trace
- Cathole trowel for sanitation in areas where a toilet is not provided
- Insect repellent
- Sunscreen for protecting the skin
- Personal care products and towel
- Cooler to store perishables and beverages. If electricity is available, a thermoelectric or stirling engine cooler can be used without the need for ice. Campers at modern campgrounds will normally bring perishable foods in coolers while backcountry campers will bring non-perishable foods such as dried fruits, nuts, jerky, and MREs.
- Bottled water or portable water filter for areas that have access to rivers or lakes
- Cooking implements such as a tripod chained grill, Dutch oven, or La Cotta clay pot can be used for cooking on a campfire. A portable stove can be used where campfires are forbidden or impractical. If using a campground with electricity, an electric frying pan or slow cooker can be used.
- Firewood for campfires
- Emergency Preparedness Kit
- Multi-Tool or knife
- Global Positioning System (GPS)
Much of the remaining needed camping equipment is commonly available in the home, including: dishes, pots, and pans; however, many people opt not to use their home items, but instead utilize equipment better tailored for camping. These amenities include heavy plastic tableware and salt and pepper shakers with tops that close in order to shelter the shakers from rain. Old kitchen gear purchased from thrift stores or garage sales may also be used in place of home items as an alternative to buying specialized (and more expensive) camping equipment. Backpackers use lightweight and portable equipment. 
Campers span a broad range of age, ability, and ruggedness, and campsites are designed in many ways as well. Many campgrounds have sites with facilities such as fire rings, barbecue grills, utilities, shared bathrooms and laundry, as well as access to nearby recreational facilities, however, not all campsites have similar levels of development. Campsites can range from a patch of dirt, to a level, paved pad with sewer and electricity with many public and private campgrounds also offering cabin options.  (For more information on facilities, see the campsite and RV park articles.)
Tent camping sites often cost less than campsites with full amenities, and most allow direct access by car. Some "walk-in" sites lie a short walk away from the nearest road, but do not require full backpacking equipment. Those who seek a rugged experience in the outdoors prefer to camp with only tents, or with no shelter at all ("under the stars").
According to an infographic produced by Red Rover Camping and based on data from the 2014 American Camper Report published by the Coleman Company, Inc. and the Outdoor Foundation, camping in the United States is gaining popularity after a fall of 4.2 million participants from 2011 to 2012. 
According to data provided by the Great British Tourism Survey conducted by Visit England, almost 4.5 million camping and caravanning holidays were taken by British residents during the first half of 2015, for an average of 3.7 nights.  As in the United States, camping is gaining popularity, with an 8% increase in trips compared to the same period in 2014. The Caravan Club and the Camping and Caravanning Club represent UK campers.
Data collected by the Fédération Nationale De L'Hôtellerie De Plein Air (FNHPA) shows that around 113 million nights were taken at French campsites in 2015, which was up by 3.9% on the same period in 2014. French holidaymakers took 77 million of these, and the rest was made up of other nationalities, the majority of whom were Dutch, German and UK tourists. The French Government hopes to have 100 million tourists each year by 2030. The most popular region for camping is Languedoc and Roussillon with around 19,331,663 nights spent at campsites during 2015, whilst the department with the most campsites is the Vendée.
