Definitely worth the visit. Entry is just $10 per adult."

Geology and Volcanic History
The landscape is characterized by vast expanses of pahoehoe and aa lava flows, interspersed with striking cinder cones and dramatic lava tubes. These tubes, formed when the surface of a lava stream cools and solidifies while molten lava continues to flow beneath, create underground caverns that visitors can explore. The monument's unique geology has made it a valuable site for planetary science research, as its volcanic features are similar to those found on the Moon, Venus, and Mars.
Understanding the volcanic processes that shaped this area enhances the visitor experience. Signs and interpretive materials throughout the park explain the formation of lava flows, cinder cones, and the geothermal features like steam vents and fumaroles. It's a living laboratory where you can witness the raw power of volcanic forces and their lasting impact on the landscape.
Exploring the Lava Tubes
The most popular tubes include the Indian Tunnel, Thousand Springs Lava Tube, and Boy Scout Cave. Visitors can walk through these tubes, often navigating over rocks and through openings. It's recommended to bring a flashlight or headlamp, as it gets very dark inside. The temperature inside the caves remains cool year-round, providing a welcome respite from the summer heat.
When exploring the lava tubes, wear sturdy shoes with good traction, as the ground can be uneven and rocky. Be mindful of your surroundings, watch your head, and stay on marked paths. The experience of being inside these ancient volcanic formations is truly memorable and offers a different perspective on the monument's geology.
Best Practices for Visiting
Stay hydrated by bringing plenty of water, as there are limited services within the monument. Wear sturdy, closed-toe shoes suitable for walking on uneven terrain, gravel paths, and potentially rocky cave floors. A headlamp or flashlight is essential for exploring the lava tubes. Remember that dogs are only permitted on the paved Loop Road and not on trails or in caves.
Finally, check for any active closures before your visit. Weather conditions and bat activity can sometimes lead to the closure of the Loop Road or specific trails and caves. The National Park Service website is the best source for up-to-date information. By planning ahead and being prepared, you can fully enjoy the unique and otherworldly experience of Craters of the Moon.
