Hiking

The Lenox Crater and Lava Flow Trail Loop offers a unique hiking experience through a volcanic landscape. You will traverse 2.6 miles (4.2 km) with a moderate difficulty, gaining 292 feet (89 metres) in elevation, which typically takes about 1 hour and 22 minutes. As you hike, you will encounter diverse terrain, from paved sections to loose cinders and rough basalt. Look out for the striking Sunset Crater Volcano, providing panoramic views, and the vast Bonito Lava Flow that shapes the area's lunar-like appearance. You will also see unique splatter cones and intricate cracks formed by cooling lava, with small ponderosa pines remarkably growing from the lava fields.

Before you start your hike, remember that the trail's surface varies significantly, including loose cinders and rough volcanic rock. Wearing sturdy footwear is highly recommended to navigate these conditions comfortably and safely. The elevation of nearly 7,000 feet can make this moderate hike feel more strenuous for some, so be prepared for the altitude. Plan your visit during cooler parts of the day, especially in warmer months, to avoid direct sun exposure on the exposed volcanic terrain. Interpretive signs along the route provide valuable information about the geological features and history of the area, enhancing your experience.

This trail stands out for its journey through a landscape shaped by recent volcanic activity. You will witness the raw power of nature, seeing how the land has been transformed by eruptions and subsequent cooling lava flows. The area's unique geology, including the black cinder hills and various volcanic formations, offers a fascinating glimpse into Earth's dynamic processes. It is a prime example of a lunar-like environment accessible for exploration, making it a notable destination within the region.

Lenox Crater

Highlight • Volcano

On this hike, you can climb a volcano! You will enjoy awesome views of the San Francisco
Peaks, Sunset Crater, and the Bonito lava flow. During the eruption of Sunset Crater Volcano almost 1,000 years ago, the ash and cinder filled in the crater at the top of Lenox Crater, which made it look like
a gentle depression in the landscape today.
