Hawaii’s lava tubes offer a unique and thrilling adventure for those seeking an off-the-beaten-path experience. Formed by flowing lava during volcanic eruptions, these underground tunnels provide a glimpse into the geological forces that shaped the islands. Exploring these natural wonders requires careful planning, respect for the environment, and a healthy dose of curiosity. This article will guide you through some of the most accessible and fascinating lava tubes in Hawaii, providing practical tips and information to make your adventure unforgettable.
Kazumura Cave: The Granddaddy of Lava Tubes
Let’s dive into Kazumura Cave, one of the longest and deepest lava tubes in the world! Located on the Big Island, Kazumura is truly a subterranean giant. Its sheer size and complexity make it a prime destination for experienced cavers and those looking for a truly challenging and rewarding adventure. Now, before you grab your headlamp and jump in, it’s crucial to understand that Kazumura is NOT a casual stroll. It’s a wild cave system, meaning it’s not developed with lights or walkways. This translates to needing a guide, proper gear (more on that later), and a decent level of fitness. Several experienced guides offer tours. Check the official website, if available, for current tour operators. Tours can range from a few hours to multi-day expeditions, and the price reflects that – expect to pay anywhere between $100 to several hundred dollars depending on the length and intensity of the tour. You’ll be navigating uneven terrain, scrambling over rocks, and possibly crawling through tight spaces, making preparation key. The beauty lies in the raw, untouched nature of the cave. You’ll witness incredible geological formations, delicate lava structures, and, if you’re quiet, maybe even spot some cave-dwelling creatures. Remember to leave no trace – pack out everything you pack in, and avoid touching the cave walls to preserve this fragile ecosystem. Respect is key when visiting such a remarkable natural wonder.
Thurston Lava Tube (Nāhuku): An Easy Introduction
For a less strenuous and more accessible lava tube experience, head to Thurston Lava Tube, also known as Nāhuku, located in Hawaiʻi Volcanoes National Park on the Big Island. This is a fantastic option for families, those with limited mobility, or anyone looking for a quick and easy introduction to the world of lava tubes. A paved path and installed lighting make Nāhuku a breeze to explore. The tube itself is relatively short, about 500 feet long, but it’s packed with geological wonders. You’ll marvel at the smooth, sculpted walls, dripping formations, and the sheer scale of the tube. While it’s easy to navigate, be sure to wear comfortable shoes, as the path can be slippery in places. The park itself charges an entrance fee, check the current rates here. Parking can be limited, especially during peak season, so aim to arrive early. Even with the lighting, bringing a small flashlight can enhance your viewing experience and allow you to spot details that might otherwise be missed. Keep an eye out for ferns and plant life near the entrance – these thrive in the humid, sheltered environment within the lava tube. After exploring Nāhuku, take some time to explore the surrounding rainforest trails for a more complete experience within the National Park. Remember that removing anything from the park is illegal due to the cultural and geological sensitivity of the area.
Kaumana Cave: A Spontaneous Adventure
Located just outside of Hilo on the Big Island, Kaumana Cave offers a more rugged and adventurous experience than Thurston Lava Tube, but without requiring a guided tour. It’s a state-owned cave, meaning its free to enter (though parking may have a fee depending on agreements between the state of Hawaii and the private owner of the parking lot), but that also means it’s also unlit and unguided, so you’ll need to bring your own light source and be prepared for a more challenging exploration. This cave is formed by the 1881 lava flow that threatened Hilo. There are two entrances to Kaumana Cave, both within a short distance of each other. Be incredibly cautious when nearing the entrances—the path leading to the entrances can be very slippery, especially after rain. Once inside, the cave floor is uneven and rocky. Sturdy footwear is essential! While the cave extends quite far, most people only explore the first section due to the increasing difficulty and darkness. The further you venture, the more challenging the terrain becomes, and the risk of getting disoriented increases. Always let someone know you’re going into the cave and when you expect to be back. If you choose to explore deeper into the cave, consider bringing a backup light source and a friend. The temperature inside the cave is noticeably cooler than outside, so a light jacket might be a good idea. The natural formations are fascinating. Be careful not to touch anything, both to protect the cave and to avoid startling any cave-dwelling creatures (like cave crickets!).
The Ape Caves (Lava Beds National Monument, CA – A Worthy Side Trip!)
Okay, this isn’t technically in Hawaii, but if you’re a lava tube enthusiast and ever find yourself in Northern California, the Ape Caves in Lava Beds National Monument, near the Oregon border, are absolutely worth a visit. These are similar in formation to Hawaiian lava tubes, but they offer a mainland United States experience. This is the longest continuous lava tube in the United States, and the Ape Cave is divided into two sections: the Upper Cave and the Lower Cave. The Upper Cave is about 1.5 miles long and has a relatively smooth floor, making it suitable for families. The Lower Cave is about 1 mile long and is more challenging, with boulder-strewn sections that require some scrambling. Entrance to the park requires an entrance fee. Check the park’s current fee schedule for details. The temperature inside the caves hovers around 42 degrees Fahrenheit year-round, so dress warmly and bring a good light source. Flashlights and headlamps are essential, and it’s a good idea to have a backup. Lava Beds National Monument offers ranger-led tours during the summer months, providing valuable insights into the geology and ecology of the caves. Check the park’s website or visitor center for tour schedules. There’s a strong emphasis on responsible caving practices. Be sure to pack out everything you pack in, avoid touching the cave walls, and stay on designated trails. The park is also home to diverse wildlife, including bats, so be respectful of their habitat. Combining a visit to the Ape Caves with other activities in Lava Beds National Monument, such as hiking or exploring other lava formations, can make for an unforgettable adventure.
Lava Tube Preparation: Gear Up for an Underground Excursion!
So, you’ve decided to explore a lava tube. Awesome! But before you descend into the depths, let’s talk about gear. Proper preparation can make or break your experience. First and foremost: Footwear is paramount. Forget your flip-flops. Sturdy hiking shoes or boots with good ankle support are essential. The terrain inside lava tubes is often uneven, rocky, and slippery. You’ll want footwear that provides traction and protection. Next up: Lighting. Don’t rely on your phone’s flashlight. Invest in a high-quality headlamp with a strong beam and long battery life. A headlamp frees up your hands for navigating the cave. It’s a good idea to bring a backup flashlight just in case. Batteries can die unexpectedly, especially in the cool, damp environment of a lava tube. Don’t get caught in the dark! Don’t forget to Dress appropriately. Even in warm climates, lava tubes can be surprisingly cool. A light jacket or sweatshirt is a must. Long pants are also recommended to protect your legs from scrapes and cuts. If you’re exploring a wild cave like Kazumura, consider wearing gloves to protect your hands. Water is essential. Being underground can be surprisingly dehydrating. Bring plenty of water to stay hydrated throughout your adventure. Snacks are also a good idea, especially if you’re planning a longer excursion. Energy bars, trail mix, or fruit can provide a quick boost when you need it. For more challenging caves, a small backpack is useful for carrying your gear, water, and snacks. A first-aid kit is always a good idea, even for short explorations. Include essentials like bandages, antiseptic wipes, and pain relievers. Finally, before you go, let someone know your plans. Tell them where you’re going, when you expect to be back, and what to do if you don’t return on time. Cell phone service is unlikely inside a lava tube, so don’t rely on it for communication.
Leave No Trace: Respecting Hawaii’s Natural Wonders
Exploring lava tubes is a privilege, and it’s crucial to minimize your impact on these delicate ecosystems. The “Leave No Trace” principles are essential for responsible caving. First, pack out everything you pack in. This includes food wrappers, water bottles, and even small items like tissues. Never leave anything behind. Minimize campfire impacts. This applies mostly to areas around the entrances of lava tubes, rather than inside. If you build a fire, use existing fire rings if available, and keep it small. Respect wildlife. Lava tubes can be home to various creatures, including bats, insects, and other cave-dwelling animals. Observe them from a distance and avoid disturbing their habitat. Never feed wildlife. Lava tubes are fragile environments, and even seemingly small actions can have a significant impact. Avoid touching the walls, as this can damage delicate formations and introduce contaminants. Stay on designated trails or paths. This helps to minimize erosion and protect sensitive areas. This minimizes erosion and protects sensitive areas. Be considerate of other visitors.
