On our way from Utah into Idaho, we decided to make a detour to Craters of the Moon National Monument—a place I wasn’t entirely sure what to expect from.
It’s strange to me that I had never visited this site before for all the many times that I had been in the area over the years. So this detour was a perfect opportunity to correct that. When we turned off from the small town of Arco I had the prickle of excitement of seeing a new place.
From a distance, the landscape already felt different. The colors shifted, the terrain flattened, and then suddenly it gave way to something that didn’t quite look like anything else we had seen on the trip.
What we found was a wide stretch of black lava rock, shaped by ancient volcanic activity and left behind in forms that felt almost otherworldly. It didn’t feel like the Idaho I had in mind—it felt quieter, harsher, and somehow a little like stepping onto another planet.
We only had a few hours to explore, but it was enough to leave an impression.

History of Craters of the Moon
The landscape at Craters of the Moon National Monument was formed by a series of volcanic eruptions that took place thousands of years ago. Rather than a single event, the area was shaped over time as lava flowed across the land, cooling into the hardened rock that now stretches for miles.
These eruptions came from deep cracks in the Earth, known as fissures, rather than a single volcanic peak. As the lava spread, it created a variety of formations—rough, jagged fields, smooth waves of rock, and underground lava tubes that still exist beneath the surface.
The name “Craters of the Moon” comes from early explorers who felt that the terrain resembled what they imagined the surface of the moon might look like. Even today, walking through the area, it’s easy to understand why. The dark rock, the wide open space, and the absence of much vegetation give it a stark, almost otherworldly feel.
In 1924, the area was designated a national monument to protect its unique volcanic features. Since then, it has become a place where visitors can explore and better understand a landscape that feels both ancient and unfamiliar.
Exploring Craters of the Moon
Stepping into Craters of the Moon National Monument felt a little like stepping into a different world.
The landscape stretched out in shades of black and gray, with jagged lava rock covering the ground in every direction. There was very little to soften it—just open sky, distant mountains, and the steady presence of wind moving across the terrain. It felt quiet, stark, and surprisingly vast.
Even before we began exploring, it was clear that this was not a place you simply pass through. It’s a place that asks you to slow down, look closer, and take in something completely different from what you might expect to find in Idaho.
With only a few hours to spend, we focused on a handful of areas that gave us a good sense of the landscape—each one offering a slightly different perspective of the lava fields.
North Crater Flow Trail
The boardwalks along the North Crater Flow Trail made it easy to walk out into the lava fields and experience the terrain up close.
From here, we could see the textures of the rock more clearly—sharp and uneven in some places, smoother and almost wave-like in others. It’s one thing to see the landscape from a distance, but walking through it gives a much better sense of how it was formed and how far it stretches.
Even with the cold and wind, this was one of the areas where we lingered the longest, taking our time to look around and take it all in.
Deviil’s Orchard
Devil’s Orchard felt like a bit of a contrast to the surrounding landscape.
Here, small patches of plant life have found a way to grow among the lava rock, creating a mix of dark stone and unexpected greenery. It’s a reminder that even in a place that feels harsh and unyielding, life still finds a way to take hold.
The short trail made it an easy stop, but one that added a different layer to our understanding of the park.
inferno Cone
Climbing up Inferno Cone was one of the more memorable parts of our visit.
The path to the top is short but steep, and with the wind picking up, it felt even more exposed. But once at the top, the view opens up in every direction—lava fields stretching out below, with mountains in the distance.
It’s one of the best vantage points in the park, and a place where you can really take in the scale of everything around you.
Broken Top
Broken Top felt a little different from the other stops—less defined, a bit more open, and shaped in a way that really showed the force behind the landscape.
This area is part of a cinder cone that was broken apart during past eruptions, leaving behind a rugged, uneven formation of lava and rock. Walking around it, you can see how the land was pushed and pulled, fractured and reshaped over time.
Big Sink Overlook
Big Sink Overlook offered a quieter moment.
Looking out across the landscape, it was easier to see the broader patterns—the way the lava had spread and settled over time. It felt less about exploring and more about observing, taking a step back and seeing the landscape as a whole.
A Note About the Caves
We had hoped to explore some of the lava tubes, but they were closed due to ice during our visit.
It was a little disappointing to miss that part of the experience, but it also felt like a reminder that this landscape is still very much shaped by the elements. Even without the caves, there was more than enough to explore and appreciate during our time there.
Seasonal Conditions
The day we visited Craters of the Moon National Monument was cold—much colder than we had expected.
The wind moved steadily across the open landscape with nothing to block it, cutting through layers and making the air feel even sharper. It wasn’t the kind of cold that encourages lingering for long stretches, and we found ourselves moving a little quicker between stops than we might have otherwise.
And yet, in a strange way, it felt fitting.
There’s something about this landscape that already feels stark and exposed, and the weather only added to that feeling. It made the experience a little more intense, a little more memorable, and very real.
But even in that cold, it was easy to imagine how different this place must feel in another season. In just a few months, the dark lava fields give way to bursts of wildflowers—color pushing up through the black rock in a way that feels almost unexpected in a place like this.
And while we experienced it in the middle of the day, it’s also known as one of the best places for stargazing. Far from the glow of any major city, the night sky here is said to stretch wide and clear, the same open landscape that feels so exposed during the day becoming the perfect place to look up and take in the stars.
We didn’t stay as long as we might have on a calmer day, but even then it was beautiful and interesting.
Tips for Visiting Craters of the Moon
If you’re planning a stop at Craters of the Moon National Monument, here are a few things to keep in mind:
Dress for changing weather
Even if it feels mild elsewhere, this area is very exposed. Wind and temperature shifts can make it feel much colder than expected.
Wear sturdy shoes
The lava rock is uneven and sharp in places. Good footwear makes exploring much more comfortable.
Plan for a few hours
You don’t need a full day to experience the park. A few hours is enough to see several key areas and get a feel for the landscape.
Check conditions ahead of time
Some areas, like the lava tubes, may be closed seasonally due to ice or safety concerns.
Take your time
Even though it may look similar at first glance, each area offers something a little different. Slowing down helps you notice those details.
Our stop at Craters of the Moon National Monument wasn’t long, but it was memorable.
It’s not a place filled with bustling activity or long lists of things to do. Instead, it offers something quieter—a chance to step into a landscape that feels completely different from the world around it.
Between the dark lava fields, the steady wind, and the sense of standing somewhere shaped by forces much older than us, it felt like a place that invites you to pause, even if only for a little while.
It may not have been the warmest or most comfortable stop on our trip, but it was one of the most unique. And sometimes, those are the places that stay with you the longest.
