Explore the Fiery Furnace
What to Expect
Safety Advisory
Getting genuinely lost in the Furnace is not a hypothetical — it happens regularly. The maze of sandstone fins creates identical-looking corridors, and GPS can be unreliable between the walls. If you go self-guided, study the orientation materials carefully and turn back if you lose your bearings.
Flash flood risk is real in the narrow passages, especially during monsoon season from July through September. Check the forecast before entering, and never go in if thunderstorms are anywhere in the region — water funnels through these slots with zero warning.
The scrambling sections involve exposed rock with significant drop potential. Some moves require using hands and feet on steep slickrock — anyone uncomfortable with Class 3 scrambling or with young children should stick to the ranger-led out-and-back option rather than the full loop.

Pro Tips
Book your permit or ranger-led tour on recreation.gov the moment reservations open — ranger hikes sell out up to a week in advance, and walk-up afternoon tickets at the visitor center are a long shot at best.
Go with a ranger your first time through, no question. The self-guided permit requires watching an orientation video, but nothing replaces having someone who knows the maze point out the hidden arches and keep you from wandering into a box canyon for an hour.
Wear shoes with serious grip — you'll be scrambling over slickrock at steep angles, and smooth soles are a recipe for a bad day. Approach shoes or sticky-rubber hiking boots are ideal. Leave the trail runners at home.
