A striking cinder cone volcano in northern Arizona, located about 25 miles north of Flagstaff within the San Francisco volcanic field. Towering 820 feet above the surrounding terrain, it features a dramatic lava flow that extends over 4 miles to the north, resembling a dark ribbon across the desert. Named humorously by a rancher in the 1880s who thought it looked like a "spilled chamber pot," S P Crater remains one of the best-preserved volcanic features in the region. Its steep slopes and unique geology even served as a training ground for Apollo astronauts simulating moon missions.

Driving & Access

• Location: Off Highway 89, about 35 minutes from Flagstaff.

• Road Conditions: The final stretch is a dirt road that becomes rough and muddy after rain—high-clearance vehicles recommended. During dry weather, a standard SUV may suffice with caution.

• Trailhead: No official signage; most visitors park near the base of the cone along the dirt access road.

Hiking & Exploring

• Summit Hike: A steep, unmarked trail leads to the crater rim. The climb is short but strenuous due to loose cinders and the steep incline.

• Lava Flow: You can follow sections of the lava flow on foot, observing the unique textures and formations.

• Skill Level: Moderate to strenuous due to slope and lack of trail maintenance. Wear sturdy hiking boots and bring plenty of water.

Pet Policy

• Pet-Friendly: Yes, dogs are allowed. However, be mindful of sharp volcanic rock and hot surfaces during warmer months. Keep pets leashed and pack out all waste.

Camping Nearby

• BLM Land: S P Crater is located on public (BLM) land, and dispersed camping is allowed nearby. There are no facilities—bring all necessary supplies and follow Leave No Trace principles.

• Sunset Crater Area: For developed campsites, head south to Bonito Campground (seasonal) near Sunset Crater Volcano National Monument.

Photography & Best Time to Visit

• Golden Hour: Sunrise and sunset cast long shadows across the crater and lava field, highlighting the rugged textures and making for dramatic shots.

• Blue Hour: The crater silhouette against a fading blue sky creates a moody, volcanic atmosphere perfect for minimalist or moody captures.

• Drone Tips: Drones are permitted, but stay well above wildlife and avoid flying in high winds common on the crater rim.

Tips & Safety

• No Facilities: Bring extra water, sun protection, and navigation tools. Cell service may be spotty.

• Wildlife: Keep an eye out for jackrabbits, coyotes, and pronghorn in the surrounding desert.

• Leave No Trace: This remote site relies on respectful visitors—stay on established paths, pack out everything, and avoid disturbing the volcanic features.

S P Crater combines a one-of-a-kind geological story with open desert solitude, making it a fascinating stop for hikers, photographers, and geology buffs traveling through northern Arizona.
