How to Do the Fiery Furnace Hike [Arches NP]

Considering doing the Fiery Furnace hike in Arches? Here’s everything you need to know to do this bucket list trail!

Arches National Park is one of the most stunning, awe-inspiring National Parks in the US. Those arches! The rock formations! The colors!

However, not only does this park have really fantastic arches, but there are some epic, non-arch rock formations, too. And the best place in Arches National Park to really explore and see some wicked awesome rock formations is on the Fiery Furnace trail.

While the Delicate Arch hike has the best viewpoint and impressive arch in the park, in our opinion, Fiery Furnace easily is the funnest hiking experience. We’ve done every trail in Arches National Park, and everyone in our family raved about this trail. It takes some planning to be able to experience this incredible spot in the park, but it’s SO worth it.

In this guide, we’re sharing how to get permits, what you need to bring with you, what it’s like exploring the Fiery Furnace, and other practical information you need to know.

Quick Tip: If you’re planning a Southwest US road trip, I recommend reserving a rental car ASAP for the best prices and availability. I always book my car with this rental car aggregate site to find the best deals.

Why is Fiery Furnace Worth Hiking?

We absolutely adored this hike. First off, because permits are so limited, you hardly see anyone else when you’re hiking.

Second, although there is an “official” trail, you are strongly encouraged to deviate from it – very unusual for a national park. Instead, you explore and make your way through the tall fins and rocky areas, often feeling like you’re the first people to explore the area.

Third and finally, the landscape is just insane.

Fiery Furnace is made up of tightly packed, long rows of alternating fins and canyons. This creates a maze-like area, with narrow passageways, sheer walls, interesting rock formations, a few arches, and a ton of opportunities to scramble over the rocks.

Put all of that together, and you’ve got one of our favorite Arches National Park hikes.

Two Ways to Experience Fiery Furnace

There are two ways to experience Fiery Furnace: on a guided ranger tour at 9am and 9:30am, OR with a self-guided permit. Tickets for both options are very limited. Ranger-guided tours are available April-October, while the self-guided permits are available year round.

Which Fiery Furnace Tour Should You Do?

We opted for the arches self guided tour. Although on the NPS website, it says to only do the self-guided tour if you’ve already done the ranger guided tour, I feel that anyone with a decent map, sense of direction, and a basic level of hiking skill will be totally fine doing the self-guided tour from the get go. And in practice, the rangers encourage anyone to do the self-guided tour as long as they commit to good practices and are able to physically handle it.

The ranger option is not a bad option and also a great way to see the Fiery Furnace and learn more about its history and geology, but you are in a bigger group and don’t explore all the little offshoots.

Given the choice, I personally would for sure choose the self-guided tour again. However, if you want to learn about the Fiery Furnace while you hike, or you don’t want to navigate yourself through the canyons and fins (it is easy to get a bit lost), then the ranger-guided hike may be the better choice for you.

How to Obtain a Reservation and Permit for the Fiery Furnace Hikes

The process for obtaining a reservation and permit for the Fiery Furnace ranger guided hike and self-guided hike are very similar.

Getting a Reservation

For both hikes, you will need to make a reservation. You can make reservations online here or by calling 877-444-6777. To make a reservation online, you will need to have an account with recreation.gov. I would recommend making sure you have an account (and remember your password) well before trying to get a reservation.

Reservations open up at 8am Mountain Time, one week in advance. As tickets for both the ranger guided tours and self-exploration tours are very limited, tickets regularly sell out – and fast – especially in the summer busy season.

For example, when we logged on to get tickets during June, it showed 65 tickets available for the self-guided tour. These tickets were gone within 30 seconds. My tip would be to keep refreshing the page regularly a minute or two before 8am, so you can grab them as soon as they become available.

If the tickets are gone before you can get them, DON’T GIVE UP! I stayed on and kept refreshing, and 3 minutes later 2 tickets became available (not enough for our group of 6), and then at 8:06, 6 tickets became available and I was able to grab them! So even if it says they’re completely sold out, keep trying for a few more minutes.

Note: When writing this post in September, I checked the ticket page and the ranger-guided tour was sold out for the upcoming week, but there actually were tickets available in the self-guided tours. So, tickets don’t always sell out immediately, but I would still prioritize getting on at 8am MT the week before to get your tickets, just to be sure.

Ticket Costs and Requirements:

For the self-guided tour, tickets cost $10 per person. For the ranger-led tour, tickets are $16 per person. This cost is in addition to the general entry you’ll pay for Arches National Park, which is $30 per vehicle, or the $80 America the Beautiful Pass.

Groups are capped at 6 people for the self-exploration tour. Groups are not allowed to congregate or merge together. For either tour, children under 5 years old are not allowed to do the hike.

Picking up Your Permit

The reservation you made online is not the permit.

For the self-guided tour, you will need to pick up your permit the day before at the Fiery Furnace Moab Information Center (in Moab) from 1-4pm, or same day at the Arches Visitor Center from 9am-4pm.

You will have to watch a video (about 8 minutes) and listen to a ranger presentation (another 10-15), plus fill out some paperwork. Plan for 30-45 minutes for this orientation and to get your permit.

Note: Your entire group is required to be present when you are picking up your permit.

For the ranger-guided tour, you will need to pick up your permit the day before at the Moab Information Center (in Moab) from 1-4pm, or same day at the Arches Visitor Center from 7:30am-8:30am. Note that it takes 30-45 minutes to get to the trailhead from the visitor’s center, and you need to be at the trailhead 5-10 minutes before your hike is scheduled to start.

Navigating Through the Fiery Furnace Trail

The fun part of doing the Fiery Furnace trail is that there isn’t really a trail! Sure, there is a general (sometimes marked) pathway that will take you through the maze of rocks, fins, canyons, and dead ends, but there’s no real trail to speak of.

Additionally, part of the fun of hiking Fiery Furnace is going off the “trail” and discovering all the fun little spots, nooks and crannies, side canyons, slot canyons, rock piles, and other fun spots. You’re encouraged to wander around a lot and “get lost” – it’s part of the fun of the Fiery Furnace!

To help you not actually get lost though, there are approximately 15 little arrows throughout the rocks that indicate the direction of the main loop. These arrows were really helpful. It’s not always easy to see them, but its also not all that hard to find them.

We noticed 3 dead end signs on the route, but every time we saw one there was something cool behind it.

So, dead end = definitely a place to check out

I would also HIGHLY recommend having a trail map downloaded on your phone. We like and use Alltrails. It costs $15 for a year subscription which gives you the ability to download maps ahead of time.

There were other spots in Arches National Park we were very happy to have the trail map (e.g. Devil’s Garden, Tower Arch), so I think it’s worth the cost even if you just use it at this national park (and honestly, I’d pay for it even if it was just for this one hike).

Because there is not a clear path to follow through the maze of canyons, pillars, and dead ends, it was extremely helpful for us to be able to refer back to our map, to make sure we were on the right track.

Of course, we went ahead and explored all the little nooks and crannies that we wanted, but it was nice to know where we were and not actually get lost.

What the Hike is Like

Okay! All the logistics are taken care of, and now you’re driving up to the trailhead. Here’s what it’s like to hike Fiery Furnace in Arches National Park.

Below is the Fiery Furnace viewpoint from the parking lot. You’ll be going down and hiking in between and around all those pillars and fins!

At the trailhead, there are lots of signs saying you must have a permit and if you don’t you can get big fines and even jail time – don’t hike without a permit!

Hiking down to the “entrance”: While you can hike clockwise or counter-clockwise, it’s recommended to go counterclockwise (so take the trail to the right from the parking lot). This way, you’ll be going the same direction as the arrows that are placed throughout the Fiery Furnace and are designed to lead you through the trail.

Entering in the furnace!

You will see lots and lots of cool features and rock formations. I loved the way this canyon curved up and around us!

There are lots and lots and lots of little offshoots, nooks, and crannies to explore:

And of course, lots of places to scramble, with occasional steep drops offs.

Occasionally there were spots we had to straddle a ledge to get across. These sections were fun, not dangerous (the dropoff wasn’t big at all), though there are places you can get hurt if you aren’t careful.

This picture really helps you appreciate all the fins in Fiery Furnace (and all the little slot canyons that it creates!)

The whole thing is very maze like. If you go down a canyon, it’s unlikely that it will loop and connect to another canyon.

Climbing down and out of the Fiery Furnace through that opening in the center.

Arches to See in the Furnace

There are at least 3 big, named arches to see as you explore the trails – Surprise, Skull, and Walk Through Bridge, plus some other, smaller arches. Walk Through Bridge is pretty easy to find, even without consulting a map (it’s down a spot marked as a dead end), but the other two are much easier to find if you have a map app on your phone.

How Long Does it Take to Hike the Fiery Furnace?

If you go straight through the trail, following the signs exactly and not doing any offshoots or extra exploring, you’ll go about 2 miles. We ended up doing about 4 miles, which took us a solid 3.5 hours, since there was a lot of technical aspects and scrambling, plus we of course took stops for pictures and snacks.

Elevation Gain: 850 feet

I feel like our elevation map really highlights the scrambly nature of the trail!

As does our route map from Alltrails:

Zooming in on the right side of the map, you can see all the little side trails, side canyons, nooks and crannies that we went and explored:

Practical Information and FAQ’s

Temperatures on the Fiery Furnace Hike

Despite the name, we found the temperatures to be quite nice during most of our time in the canyon. The tall rock walls created a lot of shade (we hiked between 8am-12pm) and so we were mostly in the shade, occasionally in the sun. Thanks to the shade, it was actually a pretty good temperature and fairly comfortable, despite highs that day being 103 F.

What is the Best Time to Hike the Fiery Furnace?

While you will never have “crowds” in the Fiery Furnace due to the limited number of permits, higher demand in summer and holiday weekends will make it more difficult to get the permits. However, be aware that it does snow in winter and snow (or rain for that matter) would make this hike much more difficult.

That said, most people do go during the summer, and I would recommend starting as early as possible, mainly to maximize the shade and lower the temperature for you, and also to avoid other people. We started around 8 a.m. and saw a couple of people at the beginning, but often felt alone.

The ranger groups start around 9 and they did catch up to us. While it wasn’t awful being by them – we enjoyed hearing some of the tidbits the ranger shared – we did deliberately go explore a side canyon to let them get ahead of us as soon as we could.

Protecting the Sand Biome

The park service really encourages you to walk on stone or in the sandy washes, not on the sandy biocrust or sandy areas that have vegetation. This is to protect the fragile desert life growing in the biocrust on the sand.

The soil crust helps keep together particles in the dirt, and traps and contains water and nutrients for the plants growing.

While it doesn’t look like much, this crust takes years to develop and is crucial for maintaining the fragile ecosystem in the arid desert of Arches.

Stay on the trails, rocks, or sandy washes, and try to stay off the sandy “sidebar” areas to help maintain this important lifeform!

Always Practice Leave No Trace

Leave No Trace involves packing out waste, not littering, respecting wildlife, not carving into the rocks, etc. Just be mindful of what you are doing and respect nature!

Is the Fiery Furnace Hike Worth It?

If it’s not already clear from my gushing review, I absolutely think the chance to hike in the Fiery Furnace is worth the time, extra cost, and extra effort to get the permits.

This truly was one of the best hikes we have ever done, bar none. Everyone had so much fun exploring and scrambling and admiring all the absolutely incredible views. Our little girls (5,  7, 9, 11) all did great on this hike and had a ton of fun. We loved the chance to explore this area that really felt like the “backcountry” in Arches National Park.

Other Places to Visit on Your Trip to Southern Utah

Arches is one of the most popular destinations in southern Utah, and you can’t miss highlights like Delicate Arch, Devil’s Garden, and Tower Arch, but there are a host of other incredible spots to visit nearby as well.

For example, you can swing by nearby Goblin Valley and freely roam through the goblin rock formations, or head down and spend a day in Capitol Reef National Park, the least visited park in Utah that is massively underrated and has beautiful rock formations.

In the southwestern corner of Utah, Zion National Park is very popular, but Bryce Canyon National Park is maybe my favorite park in Utah and can’t be missed, St George has a host of excellent hiking opportunities, and Snow Canyon State Park is a great hidden gem in Utah. Nearby Valley of Fire State Park and Cathedral Gorge State Park in Nevada have the most stunning scenery.

Grand Staircase-Escalante is a remote area of Utah that has wonders like the stunning Lower Calf Creek Falls and the insanely narrow slot canyons of Peekaboo and Spooky Gulch (which are some of my favorite slot canyons in the southwest).

In the southeastern corner of the state you’ll find gems like Valley of the Gods, Natural Bridges National Monument, and Four Corners Monument, as well as access to nearby attractions like Mesa Verde National Park in Colorado or Lake Powell and Page in Arizona.

Final Thoughts on Hiking the Fiery Furnace

Have I convinced you to try and hike Fiery Furnace? I hope so! I’ve hiked a ton in Utah and it is seriously one of my top favorite hikes in the entire state. It’s a fantastically adventurous trail among some otherworldly scenery – I hope you get the chance to experience it!
