Caving, also known as spelunking, is a recreational activity that involves exploring natural caves and underground passages. It requires physical strength, endurance, and mental fortitude to navigate through tight spaces, climb up slippery rocks, and wade through water-filled tunnels. For many people, caving is a thrilling way to connect with nature and challenge themselves in new ways.
In South Australia, caving is an especially popular activity due to the unique geology of the area. The state has an extensive network of limestone caves, granite caves, and volcanic caves that attract both novice and experienced cavers from around the world.
These underground marvels are home to stunning rock formations, crystal-clear pools of water, and unique wildlife that cannot be found anywhere else in the world. The purpose of this guide is to provide beginners with an overview of caving in South Australia.
Whether you’re planning a day trip or a multi-day expedition into the depths of the earth, this guide will provide you with essential information on safety precautions, popular caving spots in South Australia, lesser-known caves worth exploring and tips for first-time cavers. So grab your gear and let’s delve into the fascinating world of caving!
Types of Caves in South Australia
1. Limestone Caves
Limestone caves are by far the most common type of cave formation found in South Australia. These caves form over thousands of years, as rainwater and carbon dioxide dissolve the limestone rock, creating underground caverns and passages.
One of the most well-known limestone cave systems in South Australia is Naracoorte Caves National Park, which boasts more than 26 kilometers (16 miles) of underground passages. Some of the features you can expect to see in limestone caves include stalactites, stalagmites, columns, and flowstones.
2. Granite Caves
Unlike limestone caves which form through dissolution, granite caves are created through erosion. Rainwater slowly erodes away at the softer layers of rock surrounding a granite intrusion until a cave-like structure is formed.
Granite caves are relatively rare in South Australia but can be found in places such as Mount Gambier’s volcanic crater lakes region. One popular example is Engelbrecht Cave located near Mount Gambier which has been formed by underground rivers that have cut through softer rock types.
3. Volcanic Caves
Volcanic caves are formed when lava flows cool and harden on top while remaining molten beneath the surface creating tunnels or tubes for lava to flow through. When an eruption ends and the magma drains out from these tunnels, hollow spaces remain that create unique underground environments that can be explored by cavers.
Mount Gambier’s volcanic crater lakes region also boasts several volcanic caves such as Hallelujah Cave – a large chamber with high ceilings containing impressive formations like classic lava tubes.
Cavers should take note that each type of cave comes with its own distinct environment and geological features – from delicate mineral formations to stunning vistas – so it pays to explore all three different types!
Safety Precautions for Caving
1. Physical fitness and health requirements
Caving in South Australia can be physically demanding, so it is important to ensure that you are physically fit and healthy enough to undertake such an activity. Caving often involves crawling, squeezing through tight spaces, and climbing over uneven terrain. To prepare for caving, it is recommended to engage in regular exercise that improves your strength, flexibility and endurance.
Cardiovascular training such as running or cycling can help improve your stamina. It is also important to note any pre-existing medical conditions that may affect your ability to cave.
For example, people with asthma or respiratory problems may be more susceptible to breathing difficulties in the humid environment of some caves. People with back injuries or mobility issues may also need to take precautions before attempting caving.
2. Essential equipment for caving
One of the most crucial safety measures when caving is having the right equipment. Each person must have a headlamp with extra batteries, appropriate clothing (such as a helmet), sturdy hiking boots (or shoes with good grip), gloves, knee pads (for crawling), a backpack, water bottles and snacks for energy.
A whistle can also be useful if one gets lost or separated from the group. It’s essential to purchase high-quality gear that will keep you safe on your trip since you’re going into unknown terrain where there are no quick exits if something goes wrong.
3. Weather considerations
Before embarking on any caving excursion in South Australia, it is essential to check weather conditions in advance as extreme weather conditions like heavy rainstorms can make caves unsafe for exploration.
Rainwater seeps into caves and causes them to flood quickly and without warning. Some caves will close during certain times of the year due to poor weather conditions or other safety concerns.
Checking ahead will prevent unnecessary risks and ensure that you have the best experience possible. Additionally, dressing appropriately for the weather conditions is crucial to staying safe, so be sure to layer up if it’s cold and wear breathable clothing if it’s hot.
Popular Caving Spots in South Australia
South Australia is a treasure trove of natural wonders and caving spots are no exception. Two of the most popular cave systems are Naracoorte Caves National Park and Tantanoola Cave Conservation Park.
1. Naracoorte Caves National Park
Naracoorte Caves National Park is located in the southeast region of South Australia, about 350 km from Adelaide. The park boasts a total of 26 limestone caves, including Victoria Fossil Cave, which is one of the world’s most important fossil sites.
The Naracoorte Caves were formed over 500,000 years ago by rainwater seeping through cracks in the limestone. Guided tours are available with a range of options to suit your caving experience level.
For beginners, there’s the Wonambi Fossil Centre tour which provides an overview of the fossils found in the caves as well as information on how they were formed. More experienced cavers can take on Adventure Caving Tours that involve exploring unlit parts of the caves while rappelling or crawling through tight spaces.
2. Tantanoola Cave Conservation Park
Tantanoola Cave Conservation Park is located in Mount Gambier and features one long cave with guided tours available year-round. The cave was discovered by chance when a young boy was following his dog who had chased a possum into a hole that turned out to be an entrance to this incredible cave system.
The Tantanoola Cave features a range of unique formations such as stalactites, stalagmites, and helictites and has been naturally decorated with stunning colors.
During guided tours, visitors will learn about its history from knowledgeable park guides whilst witnessing its unique visual masterpiece. These two popular caving spots have much to offer for both beginner and experienced cavers alike.
With guided tours available at both Naracoorte Caves National Park and Tantanoola Cave Conservation Park, visitors can learn about the history of the caves and explore their natural beauty while feeling fully supported in a safe environment.
These cave systems should definitely be on your list of must-visit destinations if you’re planning a trip to South Australia.

Best Time to Visit South Australia for a Caving Expedition
The best time to go caving in South Australia depends on your personal preferences and the type of cave you want to explore. If you prefer mild temperatures and don’t mind crowds, consider visiting during peak season (October through April). This is when most tours operate and when many popular caves are open for exploration.
On the other hand, if you prefer cooler temperatures and more solitude, consider visiting during off-peak season (May through September). While some caves may close during this time due to weather conditions or lack of demand, there are still plenty that remain open year-round.
How To Dress Appropriately For Your Caving Trip
When it comes to dressing for a cave tour or exploration in South Australia, comfort is key. Wear comfortable shoes with good traction that can get wet or muddy if necessary – hiking boots or sneakers are ideal. Dress in layered clothing that can be easily adjusted as needed – think moisture-wicking fabrics like polyester or merino wool that will keep you warm but won’t weigh you down if they get wet.
A light rain jacket or windbreaker is also a good idea in case of inclement weather. It’s also important to bring a small backpack or fanny pack to carry any essentials, such as water, snacks, and a flashlight or headlamp (if not provided by the tour).
Avoid bringing any unnecessary items that could get in the way or be damaged in the cave. Be sure to follow any dress guidelines provided by your tour operator – some caves may require helmets or coveralls for safety reasons.
