Best Time to Visit Zion National Park

Zion month by month

Zion Canyon sits at about 4,000 feet, so it gets real desert heat in summer and cold nights in winter. The averages below are from the NPS climate chart for the park. Expect it to be 30°F or more cooler at night than in the afternoon.

Crowds follow the weather. The canyon is busiest from spring break through October and on holiday weekends, and quietest from late November through February, outside the holidays.

Spring (March to May)

Spring has comfortable hiking temperatures, with highs climbing from the mid-60s in March to the mid-80s by late May. Waterfalls and seeps are at their best, and trails like Emerald Pools and the Pa'rus Trail are pleasant all day.

The catch is the Narrows. Melting snow upstream often raises the Virgin River above 150 cubic feet per second, the level at which the park closes the Narrows to all travel. How long it stays closed depends on how much snow fell that winter, so if the Narrows is your main goal, spring is a gamble.

Spring is also busy. The 2026 shuttle season started March 7, spring break fills the canyon in March and April, and Memorial Day weekend brings long shuttle lines and full parking lots.

Summer (June to August)

Summer is the hottest and among the busiest times in Zion. Average highs on the canyon floor run 95°F to 100°F, and NPS reports multiple heat-related medical emergencies each summer. Start hikes at sunrise, carry more water than you think you need, and plan shade or river time for the afternoon.

Monsoon season runs from about July through September. Afternoon thunderstorms can build fast, and a storm miles away can send a flash flood through a slot canyon under clear skies. The park closes the Narrows whenever the National Weather Service issues a flash flood warning and keeps it closed for at least two hours after the warning is lifted.

Summer has upsides. The Narrows is usually open once snowmelt drops, the water is at its warmest, and the 2026 summer shuttle ran latest, with the last bus leaving the Zion Canyon Visitor Center at 7 p.m. from May 17 to September 12.

Fall (September to November)

Mid-September through October is the strongest window for most visitors. Highs fall from the low 90s in early September to the upper 70s in October, monsoon storms taper off, and the river is usually low. NPS describes fall as having more stable weather, with shorter days and colder water than summer.

Crowds stay high through October, especially on weekends, so ride the first shuttle (7 a.m. in fall 2026) for popular trails. By November, highs are in the 60s, crowds thin, and the shuttle season ends. In 2026 the last regular shuttle day is November 28.

Fall color in Zion Canyon comes late compared with the mountains. Cottonwoods and maples along the river and in side canyons usually turn in late October and into November.

Winter (December to February)

Winter is the quietest season. Highs average in the 50s, nights drop below freezing, and storms can bring snow to the canyon rim and occasionally the floor. Shaded trails such as the upper part of the West Rim Trail can hold ice, so traction devices help.

With no shuttle running, you can usually drive Zion Canyon Scenic Drive in your own car. For winter 2026-27, NPS lists no shuttle service from November 29 to December 25, then a holiday shuttle from December 26 to January 2, when private vehicles are not allowed on the scenic drive. Parking along the drive is limited, and NPS may temporarily close the road when lots fill.

Higher parts of the park are less reliable in winter. NPS says Kolob Terrace Road usually closes for several months from fall to spring due to snow, Lava Point Road is typically closed from fall into spring, and Kolob Canyons Road closes frequently in winter.

The Narrows by season

The bottom-up hike from the Temple of Sinawava needs no permit. The paved Riverside Walk is about 1 mile each way, and wading to Big Spring and back is a strenuous, all-day trip of about 10 miles. Top-down trips from Chamberlain's Ranch (16 miles) require a wilderness permit.

The river decides whether you can go. The park closes the Narrows when flow tops 150 cfs or a flash flood warning is in effect. Check the current flow and the flash flood forecast at the visitor center or on the park's conditions page the morning of your hike.

• Spring: high, cold water; frequent snowmelt closures.
• Summer: warmest water; afternoon flash-flood risk from July through September.
• Fall: usually the most stable conditions; colder water and shorter days by late October.
• Winter: cold water and air; most hikers rent drysuits or similar gear from outfitters in Springdale.

Shuttle season and getting around

For most of the year, Zion Canyon Scenic Drive is shuttle-only. Private vehicles cannot drive it during shuttle season, even before the first bus or after the last one. Buses come every 5 to 10 minutes in the canyon, and a separate free Springdale line runs through town.

The 2026 Zion Canyon line schedule, from NPS:

• March 7 to May 16: first bus 7 a.m., last bus from the visitor center 6 p.m.
• May 17 to September 12: 7 a.m. to 7 p.m.
• September 13 to October 24: 7 a.m. to 6 p.m.
• October 25 to November 28: 7 a.m. to 5 p.m.
• November 29 to December 25: no service; drive the canyon yourself.
• December 26 to January 2: 8 a.m. to 4:30 p.m.; scenic drive closed to private cars.
• 2027: NPS has not announced the spring 2027 shuttle schedule yet. The 2026 schedule was released in early February.

Crowds, permits and booking ahead

Zion has no entry reservation, so crowds show up as shuttle lines and full parking lots. Lots at the visitor center often fill by mid-morning in busy months. Parking in Springdale and riding the town shuttle, or walking in through the pedestrian entrance, is the easiest workaround.

A few things do need planning. Angels Landing requires a permit all year through a seasonal or day-before lottery on Recreation.gov. Watchman Campground sites open for reservation up to 6 months ahead. Entrance is $35 per private vehicle for 7 days, and non-U.S. residents now pay an extra $100 per person on top of the standard fee.

If you have flexibility, aim for weekdays in late September or October, or late April and May if the Narrows isn't a must for your trip.
