Through Stone and Shadow: Driving the Zion–Mt. Carmel Tunnel
A short, storied drive that reveals two faces of Zion—how the tunnel connects canyon to plateau.
You arrive at dawn when the desert is still cool and the sandstone seems to inhale the first light. The road that climbs out of Zion Canyon becomes a ribbon of asphalt cut into ochre cliffs; then, without fanfare, it disappears into a mouth of dark rock. For a minute you stand with your hand on the hood, listening to the cars behind you—a string of tires and engine notes that will become a metronome in the tunnel’s belly. When you drive in, the world narrows to a cone of headlight and masonry. The Zion–Mt. Carmel Tunnel is a passage not only through the mountain but through time: carved at the edge of the 20th century, it still conducts visitors from one kind of southern Utah landscape to another—slot canyons and sheer cliffs giving way to undulating, juniper-scattered plateaus.
Trail Wisdom
Check vehicle restrictions
Oversized vehicles require an escort through the tunnel—confirm dimensions and scheduling with the park before you go.
Time it for light
Drive the tunnel at golden hour for the best exterior light and fewer mid-day crowds at overlooks.
Short hike add-on
Pair the drive with the Canyon Overlook Trail (≈1 mile round trip, ~150–200 ft gain) for immediate panoramic views.
Secure gear before entry
Stow loose items and close windows—the tunnel amplifies noise and wind that can unsettle unsecured gear.
Local Knowledge
Hidden Gems
- •Canyon Overlook Trail—short, dramatic viewpoint just east of the tunnel portal
- •Checkerboard Mesa pullouts—excellent for late-afternoon light and geological study
Wildlife
Desert bighorn sheep, Mule deer
Conservation Note
High visitation has prompted management measures—increase in shuttle use, parking limits, and educational outreach—so practice Leave No Trace and follow park guidance.
The tunnel was constructed between 1927 and 1930 to connect Zion Canyon with the eastern plateaus, opening new access for motorists and visitors.
Seasonal Guide
spring
Best for: wildflower contrasts on the plateau, comfortable daytime driving, photography of thawing crevices
Challenges: variable spring storms, possible late snow at higher elevations
Spring brings milder temperatures and blooming shrubs on the east side, but be prepared for sudden weather swings that can make roads slick.
summer
Best for: long daylight for exploration, pairing with cooler morning hikes, stargazing after sunset
Challenges: heat on exposed overlooks, monsoon-driven afternoon storms
Summer offers full access and long days; travel early to avoid heat and afternoon thunderstorms that can roll in quickly.
fall
Best for: crisp air and clear vistas, fewer crowds, photography with warm tones
Challenges: cooler nights, shorter daylight hours
Fall is optimal for visibility and color contrasts—expect cooler mornings and pleasant daytime temperatures for hikes and drives.
winter
Best for: snow-dusted sandstone scenes, solitude on trails, dramatic low-angle light
Challenges: icy patches on roads and overlooks, possible temporary closures after storms
Winter delivers striking contrasts but requires caution—check road conditions and pack traction for icy pullouts.
Photographer's Notes
What to Bring
Polarizing filter
Reduces glare and saturates the blue sky and rust-red sandstone for richer photos.
Sturdy trail shoesEssential
Needed for short, exposed trails like Canyon Overlook where footing can be uneven.
Layers and wind shellEssential
Temperatures change between canyon floor and plateau; a wind shell keeps you comfortable at overlooks.
Plenty of water (1–2 liters)Essential
Hydration is important on exposed overlooks and during any hikes—carry more than you think you'll need.
Common Questions
How long is the Zion–Mt. Carmel Tunnel?
The tunnel is approximately 1.1 miles (about 1.8 kilometers) long from portal to portal.
Are vehicles allowed to drive through the tunnel?
Yes—private vehicles can drive through the tunnel; oversized or over-height vehicles must be escorted per National Park Service rules.
Is there an entrance fee to access the tunnel?
Yes, Zion National Park has an entrance fee (typically a vehicle fee valid for 7 days); check the National Park Service website for current rates.
Can I photograph from inside the tunnel?
Photography inside the tunnel is allowed—use a wide aperture, higher ISO or tripod for long exposures, and be mindful of traffic and safety.
Is the tunnel open year-round?
Generally yes, but weather events such as heavy snow or rockfall can temporarily close the road—verify conditions before driving in winter.
What nearby hikes pair well with the tunnel?
The Canyon Overlook Trail (≈1 mile round trip) is immediately adjacent to the east portal and offers a quick panoramic view of Zion Canyon.
What to Pack
Water (stay hydrated on exposed overlooks); layered jacket (temps vary between canyon and plateau); sturdy shoes (for short, uneven trails); camera with polarizer (for vivid sandstone shots).
Did You Know
The Zion–Mt. Carmel Tunnel was completed in 1930 and is approximately 1.1 miles long—an engineering milestone that significantly improved access to Zion's eastern plateaus.
Quick Travel Tips
Book oversized-vehicle escorts in advance; arrive early to avoid crowds at overlooks; carry cashless payment or park pass info for entrance fees; check NPS road conditions before driving.
Local Flavor
Springdale, the gateway town, blends canyon-side cafés and Southwestern flavors—local eateries and galleries reflect the area’s outdoor culture; recognize the park sits on traditional Southern Paiute lands.
Logistics Snapshot
Length: ~1.1 miles; Access: Zion–Mt. Carmel Highway; Fees: Zion NP entrance fee applies; Vehicle rules: size/escort requirements for oversized vehicles; Best time: early morning or late afternoon; Facilities: limited on-road services—plan ahead.
Sustainability Note
Stick to pullouts and designated viewpoints, pack out all trash, avoid disturbing native vegetation, and use established parking to minimize erosion and habitat impact.
