Yes, you can drive through Zion, but only on the Zion-Mount Carmel Highway

The Zion-Mount Carmel Highway (Utah State Route 9) is the only road that cuts through Zion National Park itself. It runs 24 miles from the park's south entrance near Springdale to the east entrance near Mount Carmel Junction. You do not need to hike or camp to use this road—it is a standard two-lane highway that stays open year-round unless weather or rockfall closes it temporarily.

The drive takes about 45 minutes to an hour depending on traffic and whether you stop at pullouts. The road climbs 2,000 feet in elevation and passes through the famous Zion-Mount Carmel Tunnel, a 1.1-mile passage carved through solid rock in 1930. The tunnel has a 12-foot-wide lane and 13.5-foot height clearance, which matters if you are towing or driving an oversized vehicle.

This is a scenic drive, not a shortcut. If you are trying to get from the west side of Utah to the east side quickly, this road saves you time. If you are just passing through the park to say you drove through it, the real Zion experience happens on foot on trails like The Narrows or Angels Landing, not from your car window.

Key Takeaways

  • The Zion-Mount Carmel Highway is open year-round but closes temporarily during heavy snow, ice, or rockfall—check the National Park Service website before you drive.
  • Vehicles taller than 13.5 feet or wider than 12 feet cannot fit through the Zion-Mount Carmel Tunnel and must use a 40-mile detour around the park.
  • The Scenic Drive inside the park (the Zion Canyon Scenic Drive) is closed to private vehicles from late March through November; a shuttle bus runs instead.
  • Fuel and services are not available inside the park, so fill up in Springdale or Kanab before entering.
  • The drive itself is free once you pay the park entrance fee, which is $35 per vehicle for a seven-day pass.

Height and width restrictions for the tunnel

The Zion-Mount Carmel Tunnel has a 13.5-foot height clearance and a 12-foot-wide lane. This eliminates most RVs, large trucks, and trailers. If your vehicle is taller than 13 feet 6 inches or wider than 12 feet, you cannot pass through.

Vehicles that exceed these dimensions must use a detour: drive north from the south entrance toward Kanab, Utah, then east on US Route 89, then south on US Route 89 Alternate. This adds roughly 40 miles and 90 minutes to your trip. The park does not charge extra for the detour—you still pay the standard $35 entrance fee.

If you are unsure about your vehicle's dimensions, measure it yourself or check your owner's manual. The park does not have a way to pre-clear oversized vehicles, so arrive early enough that if you discover you cannot fit, you have time to reroute before dark.

When the road closes and how to check conditions

The Zion-Mount Carmel Highway closes during heavy snow, ice, or rockfall. Winter closures are most common, especially after storms in December through February. Rockfall can happen any time, particularly in spring when freeze-thaw cycles loosen rock from the canyon walls.

Check the National Park Service website (nps.gov/zion) for current road conditions before you leave. The site lists active closures, weather alerts, and estimated reopening times. You can also call the park's main line at 435-772-3256. Do not rely on GPS or third-party apps—they often show the road as open when it is actually closed.

If the Zion-Mount Carmel Highway is closed, you have two options: wait for it to reopen (usually a few hours to a day after weather clears) or use the Kanab detour. The detour is always open unless conditions are severe enough to close US Route 89, which is rare.

The Scenic Drive shuttle system and private vehicle restrictions

The Zion Canyon Scenic Drive is different from the Zion-Mount Carmel Highway. It runs 7 miles up Zion Canyon from the visitor center to the Temple of Sinawava trailhead. From late March through November, private vehicles are not allowed on this road—only a free shuttle bus operates.

The shuttle runs every 15 to 30 minutes depending on the season. You board at the visitor center or at any of the nine stops along the canyon. The ride is included with your park entrance fee. This restriction exists because the canyon road is narrow and parking is limited; the shuttle moves far more people through the canyon than individual cars could.

From December through mid-March, when visitation is lower, private vehicles are allowed on the Scenic Drive. You can drive your own car up the canyon and park at pullouts or trailheads. This is the best time to visit if you want the flexibility of a private vehicle.

Fuel, services, and what to bring

There are no gas stations, restaurants, or lodging inside Zion National Park. The nearest fuel is in Springdale (west side, 1 mile from the south entrance) or Kanab (east side, 40 miles from the east entrance). Fill your tank before entering the park.

Springdale has several restaurants, shops, and hotels. Kanab is smaller but has basic services. If you are driving the Zion-Mount Carmel Highway and plan to stop at pullouts or short walks, bring water and snacks. The road itself has no services, though there are a few scenic pullouts with vault toilets.

Cell service is spotty inside the park. read offline maps before you arrive if you are using GPS. The park map is free at the entrance station and shows all pullouts and trailheads along the Zion-Mount Carmel Highway.

Entrance fees and what they cover

The park entrance fee is $35 per vehicle for a seven-day pass. This covers both the Zion-Mount Carmel Highway and the Scenic Drive (or shuttle access). Motorcycles are $30, and individuals entering on foot or bicycle are $20. An America the Beautiful Annual Pass ($80) covers all national parks for one year.

You pay the fee at the south entrance (near Springdale) or the east entrance (near Mount Carmel Junction). The fee is the same at both gates. If you enter through the east entrance and exit through the south, you pay once—the pass is valid for seven days from the date of purchase.

Driving the Zion-Mount Carmel Highway in winter

Winter driving on the Zion-Mount Carmel Highway is possible but requires caution. The road is at elevation and can ice over quickly, especially on the eastern side near the tunnel. Snow is less common than ice because the park sits in a high desert, but it does happen.

If you drive in winter, check conditions before you leave. Carry chains or a traction device if you have a rear-wheel-drive or low-clearance vehicle. The road is plowed, but black ice can form on shaded sections. Drive slowly and be prepared to turn back if conditions worsen.

Winter is also the best time to drive the Scenic Drive in your own vehicle, since the shuttle system is not running. Visitation is much lower, and you can park at trailheads without fighting for a spot. The trade-off is that some higher-elevation trails may be snow-covered or icy.

Frequently Asked Questions

Can I drive my RV through Zion?

Only if it is under 13.5 feet tall and 12 feet wide. Most RVs exceed these dimensions and must use the 40-mile Kanab detour. Measure your RV before you arrive. If you are unsure, call the park at 435-772-3256.

How long does it take to drive through Zion?

The Zion-Mount Carmel Highway takes 45 minutes to an hour without stops. If you stop at pullouts or the tunnel viewpoint, add 30 minutes to an hour. The Scenic Drive shuttle takes about 90 minutes round-trip from the visitor center.

Do I have to pay the entrance fee if I am just driving through?

Yes. Any vehicle entering the park pays the $35 entrance fee, whether you are driving through or staying for a week. The fee covers seven days of access to all park roads.

What happens if my vehicle gets stuck in the tunnel?

The tunnel is well-maintained and wide enough for standard vehicles. If you have a mechanical problem, pull to the side and call 911. Cell service is spotty, but the tunnel itself has emergency call boxes. Do not attempt to reverse out of the tunnel if you stall—wait for help.

Is the Zion-Mount Carmel Highway the fastest way across Utah?

Not necessarily. If you are traveling from Las Vegas to Salt Lake City, the Zion route adds scenic value but not much time savings. If you are coming from the west and heading east, it is a reasonable route. Check your starting and ending points against I-70 or US Route 89 to compare drive times.
