What is Caving? The Ultimate Guide to an Underground Adventure

Caving, also known as spelunking, is a thrilling exploration of natural underground environments, offering a unique blend of adventure, discovery, and connection with nature. From narrow passageways to vast subterranean chambers adorned with stunning stalactites and stalagmites, to the dramatic landscapes of lava tunnels, caving reveals the Earth's hidden wonders. Whether you're climbing through underground tunnels, marvelling at the ancient formations, or exploring the fascinating volcanic caves created by flowing lava, spelunking provides an unforgettable experience for all levels, from beginners to seasoned explorers.

The History and Origins of Caving

Caving has a rich history that spans millennia. Early humans ventured into caves for shelter, leaving behind fascinating cave paintings and artifacts that offer a glimpse into prehistoric life. Some of the most famous examples of ancient cave art can be found in the caves of Lascaux in France and Altamira in Spain, dating back more than 30,000 years.

The modern practice of caving, or speleology (the scientific study of caves), began to take shape in the 18th and 19th centuries. Explorers sought to understand the geological forces that formed these underground worlds. Among the pioneers was French geographer Édouard-Alfred Martel, often considered the father of modern caving, who led numerous expeditions into some of the deepest and most complex cave systems in Europe.

Lava tunnels (or lava tubes) have a different origin story. These volcanic formations are created when lava flows beneath the surface, cooling and hardening into long tunnels. Found in volcanic regions around the world, lava tunnels offer a different kind of caving experience, showcasing the incredible power and creativity of volcanic activity. Today, caving, whether in limestone caves or lava tunnels, is a popular recreational activity that attracts adventurers looking for unique and immersive experiences.

Types of Caving Practices

Caving can be experienced in many different ways depending on your level of skill, interest, and sense of adventure. Whether you prefer the structured environment of a show cave or the challenge of exploring wild caves or volcanic tunnels, there’s a caving style for everyone.

Show Caving

Show caving is the most accessible form of spelunking, ideal for families and beginners. These caves are developed for public tours and often include paved paths, lighting, and guided routes. For those new to caving, it’s an excellent introduction to the underground world, offering safe and comfortable exploration. Popular show caves, such as the Blue John Cavern in the UK or the Jeita Grotto in Lebanon, provide stunning natural beauty in an easily navigable format.

Wild Caving (Exploration)

For the more adventurous, wild caving allows for the exploration of undeveloped caves. Wild caving often requires crawling, climbing, and navigating through narrow tunnels or large chambers with minimal support or infrastructure. This type of spelunking offers the thrill of discovery and a raw connection with nature. Wild caving can range from relatively easy to highly technical, depending on the cave system and conditions.

Lava Tube Exploration

Exploring lava tunnels, or lava tubes, is a fascinating form of caving that takes place in volcanic regions. Unlike limestone caves formed by water erosion, lava tubes are created by the flow of molten lava beneath the Earth's surface. As the lava cools, it forms tunnels that can stretch for kilometres. Lava tubes are often easier to explore compared to traditional caves, as their passages are typically smooth and spacious. Notable examples include the Thurston Lava Tube in Hawaii and the Cueva de los Verdes in the Canary Islands. These volcanic tunnels offer a unique glimpse into Earth's fiery past.

Vertical Caving (SRT – Single Rope Technique)

For those looking for a more technical challenge, vertical caving involves descending into or ascending out of caves using ropes and specialised equipment. Known as SRT (Single Rope Technique), this form of caving is physically demanding and requires training in rope work and climbing techniques. Vertical caving allows access to deep shafts and hidden cave systems, often revealing some of the most awe-inspiring underground features.

Cave Diving

Cave diving is the most extreme and technical form of caving. It combines caving with scuba diving to explore underwater cave systems. Cave divers require specialised training and equipment to safely navigate submerged passages. This thrilling yet dangerous sport can be experienced in locations like Mexico’s cenotes or the freshwater caves of Florida, offering a surreal underwater adventure.

Essential Caving Equipment

Caving, especially in its more challenging forms, requires specific gear to ensure safety and comfort. Whether you’re venturing into a limestone cave or navigating a lava tube, the following equipment is essential:

Helmet with Headlamp

A helmet is non-negotiable when caving, protecting your head from falling rocks and low-hanging ceilings. Most helmets come equipped with a headlamp, which is crucial for navigating the dark, often pitch-black, cave environments. A reliable LED headlamp with spare batteries is essential for any caving adventure.

Caving Suit

A robust, waterproof caving suit protects you from cold, damp, and muddy conditions. Depending on the cave environment, especially in lava tunnels that tend to be drier, you may opt for a lightweight suit. In colder or wetter caves, layering thermal clothing under your suit helps regulate body temperature.

Footwear

Proper footwear is critical for maintaining grip and stability on slippery cave surfaces. Caving boots, especially those designed with ankle support and a solid grip, help you navigate rocky or uneven terrain. In lava tunnels, sturdy hiking boots with good tread are often sufficient for the relatively smoother paths.

Rope Equipment (for Vertical Caving)

For vertical caving, specialised rope equipment such as a harness, descenders, and ascenders is necessary. This equipment allows you to safely rappel down vertical shafts or climb back up. Mastering Single Rope Techniques (SRT) is essential for navigating these complex environments.

Gloves and Knee Pads

Caving often requires crawling or squeezing through tight spaces, making gloves and knee pads invaluable for protection. Padded gloves prevent your hands from getting scraped, while knee pads provide comfort and protection on rough surfaces.

Backpack with Essentials

A lightweight, durable backpack is key to carrying all necessary gear, including food, water, a first aid kit, and extra clothing. Make sure to include emergency items such as a thermal blanket, whistle, and a map of the cave system.
