Fiery Furnace

Overview

A dense labyrinth of Entrada Sandstone fins, slots, and hidden arches, Fiery Furnace is the park’s most choose-your-own-adventure experience. The name comes alive late day, when the rock glows in warm reds and oranges.

What it’s like

There’s no traditional trail inside—expect constant route-finding, backtracking from dead ends, and fun scrambling through narrow passages. Highlights often include surprise arches and dramatic light filtering between towering walls. It’s about 2 miles in total if you make a loop, but navigation makes it feel more involved.

Permits and access

Entry is controlled to protect the fragile environment. You must either book a ranger-guided hike or reserve a self-guided exploration permit in advance (through Recreation.gov). Self-guided hikers pick up permits in person and watch a short orientation about preservation and safety. Children under 5 aren’t allowed.

Difficulty and safety

This is a moderate outing with real challenges: tight squeezes, stemming, scrambles, and occasional drop-offs. It’s an easy place to get disoriented—GPS can be unreliable in the slots, so pay close attention to landmarks and subtle route cues.

Fragile landscape and wildlife

The area protects cryptobiotic soils and rare desert plants. Stay on rock or in sandy washes to avoid damage. You might spot lizards, small mammals, and birds adapted to this rocky desert world.

Logistics and amenities

There’s a dedicated parking area and trailhead with a vault toilet, but no water, food, or stores—come self-sufficient. Inside the Furnace there are no facilities.

Best time to visit

• Spring and fall are prime for cooler temps and easier permit availability (relative to peak days).
• Early morning for cooler conditions and quieter parking; late afternoon for the namesake “fiery” glow.
• Weekdays generally mean less competition for permits than weekends.

Is it for you?

If you like problem-solving, scrambling, and exploration, this is a top-tier Moab experience. If navigation isn’t your thing, opt for the ranger-led hike—same scenery, far less stress.
