Hiking the Fiery Furnace: Permits, Tips & What It's Really Like
A trail-less maze of sandstone fins in the heart of Arches — the Fiery Furnace is the park's wildest experience, and the one hike you can't just show up for. Here's exactly how the 2026 permit system works and how to make the day happen.
The maze at the heart of Arches
The Fiery Furnace isn't a trail — it's a labyrinth. Hundreds of parallel sandstone fins stand shoulder to shoulder in the middle of Arches National Park, split by narrow slots, dead-end corridors, hidden arches, and cool shaded passages where the temperature drops 20 degrees from the open desert. There's no path, no signs beyond small route arrows, and GPS barely works between the walls. That disorientation is the whole point: it's the closest thing to genuine exploration you can have in a major national park.
Because it's so easy to get lost — and because the soil and plants between the fins are fragile — the park strictly limits access. You cannot simply hike in, and commercial outfitters aren't allowed to guide inside the Furnace at all. Your two options are a ranger led loop tour or a self guided permit, both booked through Recreation.gov, both cheap, and both in real demand from spring through fall.
If you're planning a Moab trip around it, treat the Fiery Furnace as the prize you plan early for — and keep a backup in your pocket. A guided Moab hiking tour outside the Furnace delivers a similar slot-and-fin fix with zero permit lottery stress.
Local Tip Even in 100 degree July heat, the deep slots of the Furnace stay shockingly cool — it's the best midday hike in the park precisely when everything else is baking. That's the insider reason permits sell out in summer, not just spring.
Your two ways into the Fiery Furnace
Good news for the rest of your Arches trip: the park dropped its timed entry system in 2026, so the Furnace permit is now the only reservation in the entire park. Here's how the two options compare:
Honest Take First visit? Take the ranger tour. You'll see more arches than you'd ever find alone, and you can come back on a self guided permit later in the trip already knowing the lay of the fins. Plenty of Moab regulars do exactly that, in that order.
How to get a Fiery Furnace permit in 2026
-
Book on Recreation.gov at 8 AM Mountain Time
Both ranger tour tickets and self guided permits release exactly 7 days before your hike date at 8 AM MT on Recreation.gov. In peak season (spring and fall, plus summer for the shaded slots), set an alarm — popular dates can go within minutes. There's a small non refundable reservation fee per ticket.
-
Pick up the physical permit in person
Your online reservation is not your permit. Everyone in your group must appear together at the Arches Visitor Center during a scheduled pickup window — 8, 8:30, 9, 9:30, or 10 AM, or 2, 2:30, 3, or 3:30 PM — and watch a short orientation video before the paper permit is issued. Arrive 5 to 10 minutes early for the paperwork.
-
Start at the Fiery Furnace Viewpoint
The access point is the Fiery Furnace Viewpoint, about 14 miles up the park road, with restrooms at the parking area but none inside. Go in with full water bottles, follow the small route arrows if you want them, and remember the rules: stay on bare rock or in washes, keep your group together, and carry out all waste.
-
Book a guided hike outside the Furnace
Missed the window? Local guides can't operate inside the Furnace, but they run excellent fin, slot, and arch hikes on nearby public lands with the same scrambling flavor — and those you can book today, no lottery required.
Best time to hike the Fiery Furnace
| Season | Conditions | The Honest Take |
|---|---|---|
| Spring (Mar–May) | 60s–80s°F, peak demand | Ideal everywhere in the park — which means the toughest permit competition of the year. |
| Summer (Jun–Aug) | Hot outside, cool in the slots | The Furnace's secret season. Shaded corridors beat every open trail at midday. |
| Fall (Sep–Oct) | 70s–80s°F, ranger tours winding down | Beautiful light between the fins. Book the moment your 7 day window opens. |
| Winter (Nov–Feb) | Cold, no ranger tours | Self guided permits only — and the area closes entirely when snow is on the ground. |
Local Tip Doing the pickup the day before your hike is the pro move: you skip the morning logistics on hike day, and you can pair the visitor center stop with a sunset at the Windows or a Delicate Arch evening hike since you're already in the park.
What to bring into the maze
The Furnace punishes overpacking and underpacking alike — you'll be squeezing through slots barely shoulder wide, so think small pack, smart contents:
- 1–2 liters of water per person in a slim pack
- Grippy shoes with real soles — you'll smear up sandstone
- Snacks you can eat standing in the shade
- Your paper permit — rangers check inside
- A watch: GPS and phone maps fail between the fins
- Layers in shoulder seasons; the slots run cool
Leave trekking poles in the car — you'll want both hands for the scrambles and squeezes. And build in buffer time: half the fun is taking the wrong corridor twice.
Who Should Skip It The Furnace demands hands and feet scrambling, ledge walking above drop offs, and tight squeezes. Kids under 5 aren't allowed, and anyone with significant claustrophobia, a fear of heights, or limited mobility will have a better day on the park's open trails.
See the rest of Arches with a local guide
The Furnace is a half day. A guided Arches tour fills the other half with Delicate Arch views, the Windows, Balanced Rock, and the stories behind 300 million years of stone — no navigating required.

Fiery Furnace FAQ
Do I need a permit to hike the Fiery Furnace?
Yes, always. Entry requires either a ranger led loop tour ticket ($16 per person) or a self guided exploration permit ($10 per person), both reserved on Recreation.gov starting 7 days before your hike date at 8 AM Mountain Time. It's the only part of Arches that requires any reservation in 2026.
How do I pick up my Fiery Furnace permit?
In person at the Arches Visitor Center, the day before or the day of your hike, during a scheduled window: 8, 8:30, 9, 9:30, or 10 AM, or 2, 2:30, 3, or 3:30 PM. Everyone in your group must be present to watch a short orientation video before the physical permit is issued — the online reservation alone doesn't get you in.
How hard is the Fiery Furnace?
Moderately strenuous, but the difficulty is more about agility than endurance: hands and feet scrambling, ledges above drop offs, and squeezes between fins sometimes narrower than your shoulders. The ranger loop covers roughly 2 miles in about 2.5 hours. Children under 5 are not permitted.
Ranger tour or self guided — which should I choose?
First timers should take the ranger tour: you'll see hidden arches you'd never find alone and learn the geology as you go. Confident scramblers who enjoy route finding love the self guided permit's freedom. Many visitors do the tour first, then return self guided on a later trip.
Can I book a commercial guided tour of the Fiery Furnace?
No — the park prohibits commercial guiding inside the Fiery Furnace, so any tour claiming otherwise isn't going where you think. Local outfitters do run excellent guided hikes with similar fins, slots, and scrambling on public lands nearby, which you can book anytime without the permit race.
What happens if it snows or storms?
The Fiery Furnace closes when snow is on the ground and may close for flooding or other safety concerns. If the park cancels, reservations and issued permits are refunded. Flash flood risk is real in the slots during summer monsoon season — check conditions at the visitor center on hike day.
