Sunset Crater Volcano
Lava Flow Trail
If you’ve ever wanted to feel like you’re walking on the moon — minus the zero gravity and space suit, because it’s way too hot for that — the Lava Flow Trail at Sunset Crater Volcano National Monument is your ticket to a cosmic adventure right here on Earth. Located just north of Flagstaff, Arizona, this short but spectacular loop trail is a geological playground of twisted lava, volcanic bombs, and otherworldly textures that’ll make your camera sing.
Trail Overview: Clockwise is the Way to Go
The Lava Flow Trail is a 0.8-mile loop, paved in parts and easy to navigate, making it perfect for all ages and fitness levels. But don’t let the short distance fool you — this trail packs a punch in terms of scenery and science.
Starting clockwise, you’ll immediately be greeted by Sunset Crater itself, looming like a charcoal-dusted cupcake with a cherry-red summit. The volcano last erupted around 1085 AD, and the landscape still looks fresh from the oven. The trail winds through a surreal field of jagged aa lava, smooth pāhoehoe flows, and cinder dunes that crunch underfoot like volcanic Rice Krispies.
You’ll start on a paved trail from the parking lot, and even cross over an aesthetic bridge,
Geology Rocks (Literally)
Sunset Crater is a cinder cone volcano, formed when gas-charged lava exploded into the air, cooled rapidly, and fell back to Earth as cinders. These cinders piled up into the cone we see today — a textbook example of explosive volcanic architecture.
As you hike, you’ll notice the lava flows vary in texture. The aa lava is rough and clinkery (think walking on a pile of broken Legos), while the pāhoehoe lava is smooth and ropy, like someone poured black taffy across the landscape. These flows are remnants of the eruption that reshaped the region, creating a stark contrast with the surrounding ponderosa pine forests.
The Spatter Cone: Nature’s Lava Bubble
About halfway through the loop, you’ll come across a spatter cone, which is basically a mini-volcano formed when blobs of lava were ejected and piled up around a vent. It looks like a lava bubble that tried to escape but got stuck — and it’s awesome.
Spatter cones are less explosive than cinder cones, and their lava is stickier, so it doesn’t fly far. This one is a great example of how varied volcanic features can be in such a small area. It’s also a fantastic photo op — especially if you catch the light hitting its rugged surface just right.
As you circle back for the second half of the hike, you’ll follow a long fenceline before ascending a set of stairs back to the parking lot. Like there was any doubt, but the views remain amazing! The photos of the San Francisco Peaks in the background with the lava flow and pine trees in the foreground? Chef’s kiss!
Photography Tips: Lava Glamour Shots
Golden Hour Glow: The black lava absorbs light beautifully, so shoot during golden hour for dramatic contrast.
Textures Galore: Get close-ups of the lava textures — the twisted ropes of pāhoehoe and the jagged shards of ʻaʻā make for killer abstract shots.
Sunset Crater Backdrop: Frame the crater with foreground lava for a layered composition that tells the story of destruction and rebirth.
Wildlife & Flora: Look for hardy plants like penstemon and Apache plume eking out a living in the lava — they add a splash of color to your shots.
Fun Facts to Impress Your Hiking Buddies
The eruption of Sunset Crater was so intense it altered the local climate and forced ancient peoples to relocate.
The area was once used as a training ground for Apollo astronauts because of its moon-like terrain.
The monument was almost destroyed by a Hollywood film crew in the 1920s who wanted to blow up the crater for a movie. Thankfully, public outcry saved it, and it became a protected site in 1930.
Final Thoughts: Short Trail, Big Impact
The Lava Flow Trail is proof that you don’t need to hike for miles to experience something extraordinary. It’s a quick loop that delivers big on geology, history, and visual drama — perfect for photographers, science nerds, and anyone who wants to pretend they’re on Mars for a day.
So lace up your boots, charge your camera, and get ready to lava this trail like never before. Oh - and bring sunscreen!
