Guided Lava Tube Tours: A Safe First Step
For first-timers, a guided tour is highly recommended. Several reputable companies on the Big Island offer excellent lava tube tours, providing safety briefings, essential equipment, and expert knowledge. These tours often focus on accessible and well-maintained caves, ensuring a comfortable and informative experience.
One popular option is Nahuku – Thurston Lava Tube, located in Hawai’i Volcanoes National Park. Nahuku is a well-lit and relatively easy walking path through a section of a lava tube. It’s a great introduction to lava tube environments. While you can explore Nahuku on your own, ranger-led tours often provide deeper insight into the geological processes and cultural significance of the tubes. The entry fee to the park applies, but Nahuku itself is included. Note that the availability of ranger programs is subject to change, so check the park website or visitor center for the latest schedule.
Another option is booking a tour with a private company. These tours usually take you to lesser-known caves and offer smaller, more intimate experiences. They often provide headlamps, helmets, and gloves, essential for safe exploration. Prices vary depending on the duration and location of the tour, but you can expect to pay anywhere from $75 to $200 per person. Some companies will also arrange for pick up at your hotel. Be sure to research and choose a tour operator with a proven track record of safety and environmental responsibility. Ask about their safety protocols, their experience with lava tube exploration, and their commitment to minimizing their impact on these fragile ecosystems.
Independent Exploration: Proceed with Caution
For experienced cavers comfortable with self-guided exploration, the Big Island offers opportunities to venture into less-traveled lava tubes. However, it’s crucial to understand the risks and take appropriate precautions. Unlike well-maintained tourist caves, wild lava tubes can be unstable, poorly lit, and potentially dangerous. Falling rocks, uneven surfaces, and low ceilings are common hazards. Furthermore, getting lost is a real possibility, especially in complex cave systems. If you plan to explore independently, be sure to follow these essential guidelines:
Research thoroughly:
Invest time in researching the specific lava tube you plan to explore. Gather information about its length, complexity, entrance and exit points, potential hazards, and any known unstable areas. Consult maps, guidebooks, and online resources. Talk to experienced cavers or local experts for firsthand insights.
Obtain permission: Many lava tubes are located on private property. Always obtain permission from the landowner before entering. Trespassing is illegal and disrespectful. Some landowners may require you to sign a waiver or provide proof of insurance. Respect their property and follow their instructions.
Never go alone: Explore with at least three other experienced cavers. If one person gets injured, the others can provide assistance and call for help. Make sure everyone in your group is familiar with the route, potential hazards, and emergency procedures.
Inform someone of your plans: Tell a trusted friend or family member where you are going, when you expect to return, and who you are going with. Provide them with a detailed itinerary and contact information for all members of your group. Instruct them to contact emergency services if you do not return as scheduled.
Carry essential gear: This is non-negotiable. At a minimum, you will need:
Multiple light sources: A high-powered headlamp with extra batteries is essential. Carry at least one backup flashlight or headlamp per person.
Helmet: Protect your head from falling rocks and low ceilings. A climbing helmet or a sturdy construction helmet is recommended.
Gloves: Protect your hands from sharp rocks and rough surfaces. Work gloves or gardening gloves are suitable.
Sturdy footwear: Wear hiking boots or sturdy shoes with good ankle support. Avoid sandals or flip-flops.
First-aid kit: Carry a comprehensive first-aid kit that includes bandages, antiseptic wipes, pain relievers, and any personal medications you may need.
Navigation tools: Carry a map, compass, and GPS device. Learn how to use them properly. Download offline maps of the area in case you lose cell service.
Food and water: Pack plenty of water and high-energy snacks to stay hydrated and fueled.
Emergency communication device: A satellite phone or personal locator beacon (PLB) can be a lifesaver in an emergency, especially in areas with no cell service.
Protective clothing: Wear long pants and a long-sleeved shirt to protect your skin from scratches and scrapes. The temperature inside lava tubes can be cooler than the outside air, so dress in layers.
Mark your path: Use flagging tape or cairns (small piles of rocks) to mark your path, especially in complex areas. This will help you find your way back and prevent you from getting lost. Be sure to remove the flagging tape or dismantle the cairns as you leave to minimize your impact on the environment.
Be aware of your surroundings: Pay attention to your surroundings at all times. Watch out for loose rocks, uneven surfaces, and low ceilings. Avoid touching or disturbing any formations. Be respectful of the natural environment.
Leave no trace: Pack out everything you pack in. Do not leave any trash or waste behind. Minimize your impact on the environment by staying on established paths and avoiding sensitive areas.
