If you’re dreaming of a day immersed in otherworldly scenery, this guided full-day tour to Craters of the Moon National Monument & Preserve offers a fascinating mix of geology, history, and breathtaking vistas. Starting early from Twin Falls, you’ll spend around 7 to 8 hours discovering volcanic landscapes that resemble the moon’s surface — no space suit required.
At $169 per person, this tour is surprisingly good value considering the comprehensive itinerary, expert guiding, and all-inclusive features. With the convenience of pickup from your Twin Falls accommodation and a small group size (max 7 travelers), it’s designed for those who want a relaxed yet immersive experience.
What we especially appreciate is how Gabrielle, the guide, is noted for her friendly, knowledgeable, and engaging approach — making each stop feel personalized and insightful. Two particular highlights are the panoramic views from Inferno Cone and the chance to walk through the intriguing Devils Orchard. A minor consideration?

Exploring Craters of the Moon: A Detailed Look
Appreciate having local insight? Here are other guided experiences in Idaho we've examined
The Starting Point: Robert Lambert Visitor Center
We begin at the Robert Lambert Visitor Center, where you can watch films, browse exhibits, and pick up maps. It’s a friendly, interactive space that sets the tone for the day. The center’s educational displays are not just for kids — they help explain the geology and volcanic history of the landscape in a way that’s accessible and engaging. Reviewers mention how Gabrielle’s knowledge made these exhibits come alive, offering insights that deepen the experience.
North Crater Flow Trail: Walking Through Recent Lava Flows
Next, we head to the North Crater Flow, a short 1/4-mile paved trail crossing one of the youngest lava flows. Here, you’ll see crater fragments rafted by lava and get a close-up look at volcanic features formed relatively recently in geological terms. The trail’s accessibility makes it suitable for most visitors, and the vibrant spring flowers and wildlife among the rocks add a lovely touch. The free admission to this stop makes it a perfect quick exploration, setting the stage for the more dramatic sights ahead.
Devils Orchard: An Otherworldly Landscape
The walk through Devil’s Orchard is a highlight. The half-mile paved path takes you through island-like lava fragments amid cinders, creating a landscape that looks like a volcanic battlefield. Informative signs challenge visitors to think about preservation and conservation of this fragile environment, which adds an educational layer. Reviewers love the “weird features” and describe it as “thought-provoking,” emphasizing how geology and ecology intertwine here.
Inferno Cone: Panoramic Views from a Cinder Volcano
Perhaps the most iconic stop is the Inferno Cone. Climbing this ancient cinder cone (about half a mile round trip with 160 feet of elevation gain) rewards you with 360-degree views of the volcanic landscape. The ascent is manageable but offers a good workout, and the panoramic vistas make every step worthwhile. Many reviews cite this as a favorite part — “getting up to the top for the view was a highlight,” according to one traveler. Plus, knowing you’re standing atop an old volcano adds a sense of connection to the earth’s fiery past.
While in Idaho, here are other experiences we've covered
Arco’s Lava Tunnels and Spatter Cones
In the town of Arco, you explore Indian Tunnel, walking into the largest lava tunnel in the park. Its collapsed sections and ancient lava fields evoke a sense of adventure. The optional climb through the tunnel and out onto the lava fields is a fun, slightly daring activity, especially popular with families or those seeking a bit of adventure.
Next, a quick stop at the Spatter Cones — tiny volcanoes formed from eruptions throwing globs of lava into the air, which solidify into strange shapes. The short walk to the top of Snow Cone and Spatter Cone delivers a sense of the final stages of eruption activity, showcasing nature’s playful yet destructive power.
Snake River Canyon and B.A.S.E. Jumping
A drive across the I.B. Perrine Memorial Bridge offers a change of scenery and a dash of adrenaline. Spanning 1,500 feet across the canyon and soaring 486 feet above the river, it’s where B.A.S.E. jumpers leap daily — an awe-inspiring sight. Historical fans will appreciate the story of Evel Knievel’s infamous jump attempt in 1976, with his ramp still visible from the bridge. The views of the Snake River Canyon are spectacular, and watching kayakers and paddleboarders below adds to the lush contrast to the lunar landscapes.
