Go Spelunking at Lava River Cave

Attraction Introduction:
Lava River Cave, located in the Coconino National Forest near Flagstaff, Arizona, is a remarkable underground attraction created over 700,000 years ago by a volcanic eruption. It is the longest known cave of its kind in Arizona, stretching about 0.75 miles (1.2 km). This fascinating lava tube offers visitors a unique spelunking experience as they explore its dark, cool interiors marked by intriguing rock formations and lava flow remnants.

Visiting Tips:
Be sure to bring a reliable flashlight or headlamp with extra batteries, as the cave is pitch dark without any natural or artificial lighting. Wear sturdy hiking boots with good traction to navigate the uneven and rocky terrain. The temperature inside Lava River Cave remains a chilly 40°F (4°C) year-round, so dressing in layers, with a warm jacket, is recommended. The best time to visit is during the summer months when exterior temperatures are high, making the cool cave a refreshing escape.

Precautions:
The cave's entrance involves a bit of a scramble down a rocky slope, requiring good physical mobility. Visitors should be cautious of low ceilings and sharp rocks, as head injuries can occur if not careful. Bringing along a helmet is advisable for added protection. Pack out all trash and belongings to preserve the cave's natural state for future explorers. Pets are not allowed inside the cave to prevent any potential hazards or discomfort for the animals. Additionally, there are no restroom facilities at the site, so plan accordingly before arriving.
