Looking for an adventure just outside of St. George that combines geology, hiking, and hands-on exploration? The lava tubes in Snow Canyon State Park are a one-of-a-kind destination. Tucked into the rugged lava flows of Southern Utah, this trail invites you to step off the beaten path and head underground into ancient lava tunnels carved out thousands of years ago.
This short yet exciting hike offers something for everyone—from families with kids to seasoned hikers looking for a new experience. And with many of our St. George vacation rentals located near Bluff Street, Snow Canyon Drive, and West Canyon Road, it’s easy to reach the lava flow trailhead and be on your way.
What Are the Lava Tubes?
The Snow Canyon lava tubes were formed by flowing lava from prehistoric volcanic eruptions. As the surface of the lava cooled, molten rock beneath continued to move. Eventually, the lava drained out, leaving behind hollow tubes, some small and narrow, others wide enough to walk through. These formations are visible today as collapsed openings in the black rock, inviting visitors to climb in and explore.
Snow Canyon is known for its mix of red cliffs, black lava rocks, and desert landscapes. But it's the lava tubes that make this trail especially memorable. They give a real sense of the power beneath the ground and offer a unique escape from the hot Utah sun.
Getting There
To find the lava tubes, head to the Lava Flow Trailhead on the west side of Snow Canyon State Park. The trail is easy to access from central St. George, especially if you’re staying near Bluff Street or Snow Canyon Dr. There’s a small parking lot at the trailhead, and it can fill quickly on weekends, so it’s a good idea to arrive early.
- Trail length: About 2.5 miles round trip
- Lava tubes elevation gain: Roughly 170 feet
- Entrance fee: $10 per vehicle (state park fee)
The Trail Experience
This is considered an easy trail, but once you reach the tubes, expect the hike to become a bit tricky. The path winds through jagged lava rocks, loose gravel, and uneven ground. Sturdy shoes are essential, and you’ll want to keep your hands free to steady yourself while climbing or crouching.
As you follow the trail north, you’ll approach the first lava tube. It’s located just a short distance from the trailhead and is marked by a noticeable dip where the trail drops toward a collapsed tunnel. This cave is smaller but offers a good intro to what’s ahead. Keep going to find the second lava tube, a large lava tube with deeper caverns and a more open interior.
The entrance to each lava tunnel blends in with the landscape, so watch closely as you approach. You may need to turn left or climb slightly uphill to access the openings. These caves are not lit, so bring a headlamp or flashlight. The deeper you go, the darker it gets, and the light from outside fades fast.
Inside the Lava Tubes
The interior of the lava tubes stays cool year-round and offers welcome relief from the hot sun above. As you step inside, the air shifts, and the sounds of the desert quiet. The caverns echo your footsteps, and patches of light from the entrance help guide your way.
Some sections are tall enough to stand in. Others may require crawling or sliding on your hands and knees. Loose rocks, sudden drops, and low ceilings add to the thrill, so be cautious and move slowly.
The ground can be slick in places, especially near deeper sections of the second lava tube, so it’s best to explore with a partner or group. Kids love the adventure, but they’ll need supervision once inside the caves.
When to Visit
The lava tubes are open year-round, but the best seasons are spring and fall. Milder temperatures and lower sun angles make the trail more enjoyable, and you’ll find more shade along the slope near the tubes. Summer can get very hot, especially with the dark lava flows radiating heat. In winter, mornings can be cold, but the trail remains accessible unless heavy rain causes flooding.
Many hikers say the early morning is the best time to explore. The sun rises behind the cliffs and casts long shadows, creating striking contrasts along the lava flow trail and at each tunnel entrance. You’ll also avoid the crowds and find cooler temperatures.
Tips for Exploring the Lava Tubes
- Bring a real flashlight or headlamp. Phone lights won’t be enough once you're deep in the cavern.
- Wear shoes with grip. The rocks can be loose, sharp, or slippery.
- Keep both hands free for climbing in and out of tight spots.
- Don’t rush. Watch your step as the trail drops near the entrances.
- Bring water and take breaks in the shade where available.
- Stay with your group. It’s easy to lose track of time or direction inside the lava tunnels.
