Urban exploration, urbex or UE, is the examination of the normally unseen or off-limits parts of human civilization. Urban exploration is also commonly referred to as infiltration, although some people consider infiltration to be more closely associated with the exploration of active or inhabited sites. In the USA, it may also be referred to as "draining" (when exploring drains) "urban spelunking", and "urban caving."

Targets of exploration

Urban explorers do any or all of these things, but often specialize on one or two.

Abandonments

Ventures into abandoned structures are perhaps the most common example of UE. Abandoned sites are generally entered first by locals, and often sport large amounts of graffiti and other vandalism. Explorers face various risks in abandoned structures including collapsing roofs and floors, broken glass, guard dogs, the presence of chemicals, other harmful substances, most notably, asbestos, and sometimes motion detectors. Some explorers wear respirators to protect airways.

Exploration targets vary from one country to another, but some of the more popular or high-profile abandonments include grain elevators, missile silos, hospitals, lunatic asylums, and sanatoriums.

Most, if not all explorers of abandonments find the decay of inhabited spaces to be beautiful; many of these explorers are also photographers. Some abandonments are heavily guarded with motion sensors and active security. Others are more easily accessible and carry less risk of discovery. Abandonments are also popular among history buffs, 'urban archaeologists,' 'ghosthunters' and fans of graffiti art.

Active buildings

Another aspect of urban exploration is the practice of exploring active or in use buildings. This includes seeing secured or "member-only" areas, mechanical rooms, roofs, elevator rooms, and other normally unseen parts of such buildings. The term 'infilitration' is often associated with the exploration of active structures.

Catacombs

Catacombs such as those found in Paris, Rome and Naples are targets for many urban explorers. The catacombs under Paris, for instance, have been considered the 'Holy Grail' by some due to their extensive nature.

Sewers and storm drains

Entry into storm drains, or draining, is another common form of UE. Groups devoted to the task have arisen, such as the Cave Clan in Australia. Draining has a specialized set of guidelines, the foremost of which is "When it rains, no drains."

A small subset of explorers enter sanitary sewers. Sometimes they are the only connection to caves or other subterranean feature. Sewers are among the most dangerous locations to explore.

Transit tunnels

The subset of urban exploration deals with exploring active and abandoned subway and underground railway tunnels and bores. Since these are in major cities, they carry stiff penalties if one should be caught while trespassing in these, especially after the September 11, 2001 terriorist attacks. As a result, this type of exploration is rarely publicised. Although they exist worldwide, those who partake in this often reside near New York City, Toronto, London, and Moscow, along with many other major cities throughout the world.

Utility tunnels

Universities and other large institutions, such as hospitals, often distribute steam for heating buildings from a central heating plant. These steam ducts are generally run through utility tunnels, which are often accessible solely for the purposes of maintenance. Many of these steam tunnels, such as those on college campuses, often also have a tradition of exploration by students. This was once called vadding at MIT, though students there now refer to it as roof and tunnel hacking.

Steam tunnels in general have been getting more secure in recent years, due to their use for carrying network backbones and perceived risk of their use in terrorist activities, safety and liability.

Some steam tunnels have dirt floors, no lighting and can have temperatures upwards of 115 degrees Farenheit. Others have concrete floors, bright light, and can even be quite nice and feature a cool temperate. Most steam tunnels have large intake fans to bring in fresh air, and push all of the hot air out the back.

Ethics

Most urban explorers understand the risks that they face if caught while trespassing. The crime is generally seen as a means to an end, however, rather than being the focal point of the hobby. Some urban explorers tend to stick to a basic set of "ethical practices" out of respect for the locations that they visit, as well as for any other explorers who may want to visit later. The hobby, however, is still ultimately an unstructured one, and there are rarely two explorers who share the same views on ethics.

The idea behind these ethical practices is to leave buildings in the same state that they were in before they were visited. The common, but not always entirely accurate catchphrase for this ethical standpoint is the Sierra Club's motto: "take nothing but pictures, leave nothing but footprints." The common code of ethics that some adhere to frowns heavily upon theft, vandalism, tagging, graffiti, and any other crime except for trespassing.

Exceptions to these rules do exist. Graffiti in drains is sometimes condoned or encouraged in some circles, as long as speleothems and other features aren't damaged. Drainers may use it to indicate how far down the drain a given explorer has been. Some explorers remove items from abandoned sites, to preserve them or to keep as souvenirs.

Many locations contain a small area reserved for leaving tags, known as a guest book. These vary from actual books to blackboards to pieces of scrap metal or wood, or even the dust on an old piece of machinery. Rarely, employee guestbooks will be found, made before the business in question closed.

Popularity

The discussion of the popular culture revolving around urban exploration has often been discussed on multiple discussion forums. Most center around the television shows, such as "Urban Explorers" on the Discovery Channel, The Atlantic Paranormal Society, or a MTV special where they investigate a 'haunted' location. One such web-blogger wrote a lengthy article with his viewpoint on this subject, which can be touchy in the respect that many people hold different perceptions on this growing popular event, especially with middle and high schoolers. The 'underground' hobby that urban exploration began as is slowly becoming exploited and placed into todays mainstream media to the disdain of many experienced and long-time explorers.

An article on the online magazine Dragonfire describes how the growing popularity of the urban exploration field has lent itself to increased attention, not just from explorers but from vandals and law enforcement. The discussion revolves around two feuding web-sites, Urban Exploration Resource and Deggi5, to which the argument revolves around the online presence and the shopping cart structure of many online sites.

The community is becoming so involved it is even beginning to take diverse turns into other genres within itself. With many events throughout the world focused on exploration, it has spawned a diverse collection of sub-events, such as barbeques, watching "urban exploration"-themed movies, and campouts.
