Amboy Crater: Exploring a Unique Volcanic Landmark
Amboy Crater is a striking geological feature located in California’s Mojave Desert, celebrated for its perfect volcanic symmetry and unique desert terrain.
The 250-foot-high cinder cone, formed of ash and cinders, is a standout in one of the youngest volcanic fields in the United States. With its designation as a National Natural Landmark in 1973, Amboy Crater draws visitors for hiking, photography, and exploring its rugged, lunar-like landscape.
Positioned along the historic Route 66, the crater is situated roughly halfway between Barstow and Needles, making it an intriguing stop for desert travelers.

Destination Overview
Situated in a stark, open desert landscape, Amboy Crater is a classic example of a volcanic cinder cone with a symmetrical shape and a breach on its western side where basaltic lava once flowed.
The volcanic activity that created the crater has resulted in a terrain rich with geological features, including spatter cones, collapsed lava tubes, and extensive basalt fields covering about 24 square miles.
The site features a hiking trail leading to the rim of the crater, allowing visitors to peer into its interior and enjoy panoramic views of the desert. The trail includes rest stations and informative signs detailing the area’s volcanic history. Hikers can explore the rugged pathways leading to the summit, which provide a moderate challenge with uneven terrain.
Things to Do
- Hiking: The main trail to the crater’s rim is a 3-mile round-trip journey that winds through lava fields and ends at a breathtaking overlook. The trail is not particularly steep but can be challenging due to heat and rough ground.
- Photography: Amboy Crater’s stark, black rock set against the bright desert floor makes it a striking photographic subject, especially at sunrise or sunset when shadows play across the landscape.
- Picnicking: The site includes picnic tables and shaded areas for rest, making it a convenient spot for lunch before or after your hike.
Before You Go
Temperatures in the Mojave Desert can be extreme, especially in the summer months. Visitors should come prepared with plenty of water, sun protection, and weather-appropriate clothing.
Cell service may be unreliable, so downloading maps in advance is recommended. The area’s remote nature and unique terrain offer a memorable experience, but safety and preparation are essential for a successful visit.
