The Lava River Cave was formed approximately 200,000 years ago during a period of intense volcanic activity in the Flagstaff area. Volcanic eruptions spewed forth molten lava that cooled and solidified on contact with the air, forming a thick, glassy crust known as obsidian. Over time, groundwater seeped into cracks and fissures within the lava flows, eroding the rock and creating a network of underground channels and caverns.

The cave is approximately 4 miles (6.4 km) long and extends an estimated 100 feet (30 meters) below the surface.
The lava flows that formed the cave were once magma-rich, with temperatures reaching up to 2,000°F (1,093°C).
The cave's unique geology has created a variety of fascinating rock formations, including lava stalactites and stalagmites.
Visitors can walk through approximately 1.5 miles (2.4 km) of the cave's accessible passageways.

Practical Tips for Exploring Lava River Cave

Before you head out to explore this incredible natural wonder, make sure to:
