Exploring caves as part of a leisure activity is referred to as caving. The scientific study of caves and the environment of caverns is referred to as speleology.

The obstacles that must be overcome throughout the sport vary according on the cave that is being explored, however they often consist of pitches, squeezes, and water. It is frequently essential to climb or crawl, and ropes are used extensively in this process.

Many people participate in caving simply because they find the sport enjoyable or because they want to get some exercise, while for others, the primary motivation is to conduct original research in the fields of physical or biological science. Cave networks that have not yet been explored are among the few remaining uncharted areas on Earth, and researchers are exerting a lot of effort to find and access these caves. In locations that have been extensively investigated, such as the majority of nations in the first world, the caves that are easiest to reach have already been examined, and acquiring access to new caverns often involves digging or diving.

Cave exploration was originally a necessary activity that dates back thousands of years; but, in the past century or so, caving has evolved into a popular recreational hobby. Cave exploration has seen significant development in the last several decades as a result of the availability of contemporary safety gear and clothing. Some people have just somewhat lately begun to refer to it as a “extreme sport” (though not commonly considered as such by its practitioners, who may dislike the term for its perceived connotation of disregard for safety.)

The sports of mine exploration and urban exploration both make use of many of the same abilities that are developed via caving.

Practice and equipment People wear helmets to protect their heads from knocks and pebbles that may fall from above. In order to prevent the caver from having to use their hands, the main source of light is often attached to the caver’s helmet. Electric lights are the most typical, with halogen lamps serving as the industry standard and white LEDs serving as the newest and most cutting-edge alternative technology. Many cave explorers bring along not one, but two different kinds of lighting equipment, using one as their main source and the other as a backup in case the primary source stops working. Even now, carbide-based devices are widely used, particularly on excursions. It is common practise to have spare flashlights, although it is strongly advised that you not use anything larger than a mini-mag (a very small version of the popular Maglite flashlight). The climate of the cave being explored and the traditions of the people who live there both have an impact on the kinds of garments that are worn underground. In frigid caves, the caver may choose to wear a warm base layer that maintains its insulating properties when wet, such as a fleece (‘furry’) suit and/or polypropylene underwear, in addition to an oversuit made of a material that is either hard-wearing (e.g., cordura) and/or waterproof (e.g., PVC). This combination is intended to keep the caver warm and dry. It is feasible to wear lighter clothes in warm caves, especially if the cave is dry. In tropical caverns, lightweight clothing made of polypropylene is used instead, since it provides some abrasion protection while still allowing the wearer to keep as cool as possible. If the cave is very damp or if it has stream tunnels, wetsuits can be a good idea to wear. Boots are worn on the feet; in dry caverns, hiking-style boots are appropriate, however in wetter caves, rubber boots (such as wellies) and neoprene socks (sometimes known as “wetsocks”) are more common. When crawling, many people choose to protect their joints using knee pads (and sometimes elbow protection as well). Gloves are used in practically every situation. Ropes may be used for either lowering or raising oneself up a pitch using the “Single Rope Technique,” or they can be utilised for defence. The figure-of-eight loop, sometimes known as the figure-nine loop, the bowline, the alpine butterfly, and the Italian hitch are some of the most frequent knots used in caving. Carabiners, slings, and bolts are the typical components used for rigging ropes. Cave explorers bring packs with them that include things like first-aid kits, food, additional equipment, and supplies for the restroom. Cave explorers are required to bring their waste out with them, and so-called “pee bottles” have become the industry norm. For the disposal of solid trash, numerous bags of the zip-lock kind are used, layered one within the other, and then wrapped in aluminium foil (for aesthetic reasons). “Cave burritos” is a term of endearment that is used to refer to them.
Caves may be very hazardous environments; the primary dangers are cold, falling, floods, and tiredness from physical exertion. The process of rescuing someone who is buried underground is challenging and time-consuming, and it involves specialised knowledge, training, and equipment. Cave rescue operations of any significant size often need the participation of hundreds of rescue professionals, all of whom run the risk of being endangered in the course of their task. Having said that, caving is not always a pastime that is fraught with danger (especially if it does not involve difficult climbs or diving). When it comes to any kind of physical activity, recognising your limits is really essential. A variety of strategies are used in order to reduce the risks: Making sure there won’t be any problems with floods while we’re out there exploring. Rainwater that is channelled underground may swiftly fill a cave, even though the cave’s entrance may seem to be dry. Using cave teams consisting of at least four spelunkers. (In the event of an injury, one of the cave explorers will remain with the victim while the other two will seek assistance.) Having a “call-out person” who, in the event that the party does not return by the allotted time, will alert the relevant rescue personnel to the situation. Make use of lights that are installed on your helmet and bring along additional batteries. However, it is normal practise among European cavers to use just two lights, despite the fact that American cavers usually urge using a minimum of three independent sources of light per person. To lessen the severity of the effects of abrasions, cave falls, and things that may be dropped, it is essential to wear protective headgear, sturdy clothes, and boots. Cotton materials are substantially inferior to synthetic fibres and woollens because synthetic fibres and woollens dry rapidly, shed water, and remain warm while wet, but cotton materials retain water and increase the danger of hypothermia. It is also beneficial to have many layers of clothes, which may either be removed (and stowed in the pack) or added as necessary depending on the temperature and conditions. Wetsuits, either partial or complete, are recommended for use in aquatic cave tunnels because they lower the danger of hypothermia. Cave tunnels seem different from various directions. Even expert cavers might become lost in tunnels that are particularly extensive or intricate. It is vital for the exploring group to commit to memory the look of major navigational landmarks in the cave as they are traversed in order to minimise the chance of getting disoriented within the cave. The ability to recall the way out of the cave is something that each member of a caving group is expected to have memorised. In some caves, it is possible that it is acceptable to mark a small number of key junctions with small stacks or “cairns” of rocks, or to leave a non-permanent mark such as high-visibility flagging tape tied to a projection. Alternatively, it may be acceptable to mark the key junctions with a non-rock object. For vertical caving, ladders or SRT are required (Single Rope Technique). Before venturing underground to practise SRT, one must first complete the necessary training since it is a difficult skill.

Many cave habitats are quite delicate. Cave-dwelling animals are also very vulnerable, and it’s not uncommon for one specific species to be endemic to that cave alone, meaning it can only be found in that cave and nowhere else on the planet. Cave-dwelling animals are acclimated to an environment that is almost always the same in terms of temperature and humidity; as a result, the life cycles of these species are easily thrown off by any disruption. Even while animals living in caves aren’t always easy to see right away, they are nonetheless likely to be present in the vast majority of caverns. Cave-dwelling animals may be rather vulnerable, and bats are one such species. In spite of their often terrifying portrayal in works of fiction and on screen, bats really have a greater reason to be afraid of people than they do of each other. Bats have a vital ecological function in lowering the number of insect pest populations and pollinating a variety of plant species, both of which may be helpful to people in a number of different ways. Bats are at their most vulnerable during the winter hibernation season, when there is no food source on the surface to replace the bat’s reserve of energy should it be roused from hibernation. This makes bats particularly susceptible to being eaten by predators. Caves that are home to bats should not be visited during the winter months since this is the time of year when bats are at their most sensitive and fragile. Some cave tunnels may be marked with flagging tape or other indications to identify sections that are archaeologically important, ecologically sensitive, or aesthetically sensitive. The untouched sand or silt that covers the bottom of the cave might be thousands of years old, going back to the period when water stopped flowing through the cave. Marked routes could be particularly unstable. These deposits are especially vulnerable to being ruined permanently if even a single step is taken in the wrong direction. Active formations such as flowstone may have a muddy footprint or fingerprint left on them, and ancient human artefacts such as fibre products can even shatter to dust if even the most cautious archaeologist touches them.
