Snow Canyon State Park

Located in southern Utah, just outside of St. George, Snow Canyon State Park features a variety of unique landscapes, from basalt lava tubes to rocky slot canyons, caves, and swirly petrified sand dunes.

Snow Canyon State Park spans 7,400 acres in the Red Cliffs Preservation Area. Snow Canyon not only offers a selection of awesome hiking trails but also has a 3-mile paved bike path and 15 miles of trails for horseback riding.

Located about an hour from Zion National Park, Snow Canyon State Park is a lesser-known spot that makes for a great detour on any southern Utah road trip!

Petrified Dunes in Snow Canyon

The Petrified Sand Dunes in Snow Canyon State Park are made up of petrified Navajo Sandstone in vibrant shades of orange, coral, and white with layerd swirls carved into the rock.

Nearly 200 million years ago, the area that is now Snow Canyon State Park was covered in sand. Slowly the massive sand dunes solidified into sandstone, and over time water shaped the rock into the features that we see today!

The Petrified Dunes in Snow Canyon can be accessed via an easy 1.2 mile roundtrip hike that is great for kids and hikers of all skill levels!

When is the best time to hike?

The best time to hike in Snow Canyon State Park is during the winter, spring and fall. We’ve hiked the Petrified Dunes Trail twice in February, and it was lovely! Mid-50’s and sunny – the perfect weather for hiking. However, weather during the winter can be a bit unpredictable and snow is possible, so the most reliable time to visit is spring and fall.

Summer in Snow Canyon gets very hot, with average temperatures in the area reaching 100 degrees or higher! The Petrified Dunes Trail offers no shade, so we wouldn’t recommend hiking from June through August. 

Petrified Dunes Trail packing list

In addition to your standard hiking gear, below are a few items to make sure you pack for hiking the Petrified Dunes Trail.

  • Sun protection (sunscreen, chapstick and sunglasses) | There is no shade on this trail and the desert sun is intense!
  • Hiking boots | It’s good to have some traction on your shoes for climbing up the petrified dunes.
  • Snacks, lunch and plenty of water | I always hike with my Camelbak Helena – it’s the perfect size for storing the essentials for a day hike and comes with a 2 liter bladder.
  • Utah state parks pass (if you have one)
  • Hiking pants (Hers: Athleta Headlands pants, His: PrAna Stretch Zion Pants) | These Athleta pants are Sarah’s absolute favorite! They’re comfortable and durable for hiking, and all the pockets make them more stylish, so they can double as normal pants.

Things to know before you hike

Below are a few important details to be aware of before you hike:

  • Snow Canyon State Park charges a $10 fee for Utah residents and $15 fee for out-of-staters. You can pay with cash at the park entrance or online here. 
  • Utah also offers an annual state park pass for $100 for Utah residents or $150 for out of state residents – a bit pricey and likely not worth it unless you live in Utah or plan to visit many Utah state parks. 
  • The main parking lot for the Petrified Dunes Trail is fairly small and may fill up. If you aren’t able to secure a spot, you can also reach the dunes from the Lava Tubes trailhead (3.2 mile hike) or the Hidden Pinyon trailhead (1.8 mile hike).
  • Dogs are not permitted on the trail.
  • Keep an eye out for round trail markers to keep you on track. However, once you reach the top of the dunes, you can branch out and explore as you please.

In the section below, we will detail each section of the Petrified Dunes Trail so you know what to expect from the hike.

Our experience

I hiked the Petrified Dunes Trail solo on a President’s Day holiday, while Matt had to work. I loved this hike so much that I brought Matt back with me the next weekend!

On my first hike, I just did the 1.2-mile trail out and back to the Petrified Dunes. The weather was looking questionable and I didn’t want to be caught on top of a mound of rock in a thunderstorm! As such, I was a bit rushed but quickly fell in love with the area!

I knew I had to come back to complete the full Snow Canyon Loop.

Parking and getting to the trailhead

The most direct hike to the Petrified Sand Dunes leaves from the Petrified Dunes Trailhead for a 1.2 mile out and back hike.

The trailhead is located just 5 minutes past the entrance to Snow Canyon State Park, 10 minutes from Ivins, and 20 minutes from St. George. The road to the trailhead and parking lot are paved and well maintained, so you should have no trouble accessing the hike with any vehicle.

If you aren’t able to get a parking spot at the Petrified Dunes Trailhead, or you’re interested in a longer hike, you can also start from the following trailheads:

Starting the hike

From the parking lot, you can see other hikers climbing on the dunes in the distance. The trail starts out through sand and eventually leads onto the rocky dunes. There are round trail markers to designate the trail, which are helpful if you plan to continue along the Snow Canyon loop trail.

Exploring the Petrified Dunes

Once you arrive at the dunes, you can choose your own adventure and explore as you please! Out and back to the dunes is just about one mile, but you can easily rack up some additional mileage exploring.

From the top of the dunes, you have an incredible view looking down Snow Canyon, with it’s orange and white striped canyon walls and jagged pinnacles.

Snow Canyon Lava Tubes

To extend your hike and check out one of Snow Canyon’s most unique landscapes, continue to the Lava Tubes.

The Lava Tubes are massive underground caves of solidified basalt, the black, jagged rock you see in the photos below. Millions of years ago, the tubes were filled with flowing lava, which slowly hardened and left behind the caves you can see today!

Adding on the detour to the Lava Caves adds about 1.2 miles, for a 2.4 mile round trip hike.

Snow Canyon Loop: Lava Tubes & Petrified Dunes

  • Hiking distance | 3.5 miles
  • Elevation gain | 500 feet
  • Total time | 2 hours
  • Epic-ness rating | 6
  • Difficulty | Moderate
