Best time to visit Zion

The best time to visit Zion is April, May or October for walking weather. For the Narrows it is summer and early autumn, between the spring snowmelt and the cold water of winter. Each season trades one problem for another: spring brings high water, summer brings 100°F days and flash floods, and winter takes away the shuttle. The park had 4,984,525 recreation visits in 2025, and no month that year had fewer than 149,000.

The hub guide to Zion National Park covers the shuttle, the permits and the entrances; this page goes through the calendar month by month. We read the figures below on 30 October 2026 on the Park Service's pages and visitor counts, NOAA's 1991 to 2020 climate normals and Recreation.gov.

What is each month like in Zion Canyon?

Each month in Zion Canyon has its own mix of heat, crowds, shuttle hours and river level, and the table below puts them side by side. The weather is NOAA's normal for its station on the canyon floor, at about 4,040 feet; the visits are the Park Service's 2025 counts.

The canyon floor sees only 4.0 inches of snow in a normal year, nearly all of it from December to March. Frost is common in that season, with a low at or below freezing on about 20 nights in December and 18 in January. The day-to-night swing is widest in June, at 33°F on average.

Why was May busier than July in 2025?

May was the busiest month at Zion in 2025, with 589,279 visits, just ahead of June at 585,040. April came third and July only fourth, at 529,798. October, with 504,122, beat August by 27,465.

The familiar picture of a June and July peak comes from the Park Service's averages for 2019 to 2023, which put June at 556,426 and July at 554,096. That pattern did not hold in 2025, and in 2024 the peak was June alone, at 613,552. In both years October drew more visitors than August.

The Park Service warns that summer visitors share the park with around half a million people each month, and that parking is often full by 9 a.m. From mid-March to late November, the park says, its campgrounds are full almost every night. Our guide to where to stay near Zion compares Springdale, the lodge and the towns further out.

Certain weekends are busier than any month average. The Park Service names Easter week, Memorial Day weekend, Independence Day, Pioneer Day on 24 July and Labor Day weekend. Memorial Day weekend 2025 alone brought over 95,000 visits. In 2027 Easter Sunday falls on 28 March and Memorial Day on 31 May. The guide Best time to visit the USA lists every 2027 federal holiday weekend and the season in each region.

How many 100°F days does the canyon floor get?

Zion Canyon gets 50.5 days at or above 100°F in a normal year, almost all of them from June to August. The NOAA normals below count the average number of days in each month that reach each mark.

The Park Service asks every visitor to carry at least one gallon of water per person per day, and to drink it. Water can be refilled at the visitor centres, campgrounds, Zion Lodge and some shuttle stops. Ahead of the Independence Day weekend in 2026, the park advised three to four litres of water, salty snacks and sun protection. It also told hikers to start early, return early and rest in the shade.

Heat exhaustion comes first, when the body loses more fluid than it takes in. Heat stroke is the emergency: the body can no longer cool itself, and confusion or a change in behaviour are the warning signs. The Park Service says to cool the person by any available means and get medical help at once.

When is the Virgin River low enough for the Narrows?

The Virgin River is low enough for the Narrows most reliably in summer and early autumn, which is when the Park Service says most people hike it. The route closes to everyone above 150 cubic feet per second, and during a flash-flood warning plus at least two hours after it is lifted. Below 70 cubic feet per second the crossings are knee-deep; between 70 and 150 they reach the thigh, and pools can be chest-deep.

Spring snowmelt is the long closure. The Park Service's own record shows the river above the line most of the time in these years:

The record covers 15 years, 2012 to 2026, and the Narrows closed in 8 of them, for between 2 and 77 days. Seven of those closures began in April and one in March. The river was open most of the time in 2014, 2015, 2018, 2021, 2022, 2025 and 2026. A spring trip built around the Narrows is therefore close to a coin toss.

Water temperature changes the gear more than the season does. The Park Service gives these averages for the river:

• Summer: 56 to 68°F. The river can feel cool even in mid-summer.
• Spring and autumn: 41 to 53°F. Neoprene socks, trousers or a wetsuit may be necessary.
• Winter: 38 to 45°F. A wetsuit or drysuit with warm layers may be needed, and ice can form.

The bottom-up walk to Big Spring needs no permit; the Park Service calls it a 9.4-mile out-and-back on one page and a ten-mile round trip on another. The park neither sells nor rents gear, so shoes, a stick and any drysuit have to come from outside the park.

How dangerous is the July-to-September monsoon?

The monsoon in Zion runs from July to September, the Park Service says, and it is the peak season for flash floods. Moist air fuels unstable weather, and the Narrows drain a watershed of 288 square miles. A storm 15 to 20 miles upstream can raise the river where visitors never see the rain.

The monsoon is not the wettest season by volume. NOAA's normals put 47.3% of the canyon's 16.27 inches a year in December to March, and only 24.3% in July to September. The danger is heavy rain arriving all at once. The Park Service warns of floods "even with sunny skies overhead" and says there is never a zero chance of flooding.

The park uses the National Weather Service's flash-flood scale: not expected, possible, probable and expected. Any of the last three should be taken seriously, and the park may close the Narrows and every slot canyon. Lightning is the second risk, and the Park Service calls it dangerous to be on Angels Landing during rain or a thunderstorm.

When do the cottonwoods turn gold in Zion Canyon?

The cottonwoods in Zion Canyon turn gold at the end of October and in early November, on the Park Service's seasons page. Two older Park Service texts give different peaks: early November in a 2011 photo caption, and around mid-November in a 2011 audio script. All three describe the canyon floor, so the honest window is late October to mid-November, depending on the year.

The audio script names the trees: cottonwoods and box elders turn gold, and the bigtooth maples along the Emerald Pools Trail turn crimson. The cover photo above was taken on 7 November 2009. The east side of the park sits higher and runs 5 to 10 degrees cooler, so its colours peak earlier, according to the same photo caption. The park's pages carried no colour report for 2026 when we read them.

Autumn days still swing by about 30°F between afternoon and night. The Park Service says visits slow in autumn and drop more sharply in November: in 2025 November had 38.4% fewer visits than October. Thanksgiving weekend is the exception, with long waits for the shuttle; in 2026 it falls on 26 November, two days before the last bus of the season.

Can you drive the Zion Canyon Scenic Drive in winter?

The Zion Canyon Scenic Drive opens to private cars in winter, but only in the weeks without shuttle buses. The 2026 timetable has no buses from 29 November to 25 December, holiday buses from 26 December to 2 January, and none from 3 January until spring. The Park Service says cars may usually drive it from December through February.

The previous winter shows how that works in practice. Cars could drive the road from 1 to 22 December 2025, buses ran from 23 December to 3 January, and cars returned from 4 January. The Park Service had not published its car dates for the winter of 2026 to 2027 by 30 October 2026.

Winter is quieter but not empty. The road closes for the day when its legal parking is full, which the Park Service says happens often in December, January and February. Presidents Day weekend is one of the busiest of the winter, with no shuttle in 2026; in 2027 it falls on 15 February. January and February 2025 ran 15% and 17% above the 2019 to 2023 averages.

The shuttle's spring start has moved by a few days each year: 3 March in 2024, 2 March in 2025 and 7 March in 2026. The 2027 date had not been published by 30 October 2026.

Which roads close for snow and rockfall, from Kolob Terrace to the tunnel?

The roads to Zion's high country close first in winter, while the canyon floor stays open. On the canyon floor snow usually melts within hours after a storm, but it builds up on the higher ground. The Park Service recommends traction devices for boots, and some trails may close for falling ice.

• Kolob Terrace Road: usually closed for several months from autumn to spring, from Maloney Hill, about a mile beyond the Hop Valley Trailhead.
• Lava Point Road: typically closed from autumn into spring.
• Kolob Canyons Road: open most of the year, but closes often in winter for snow or ice.
• Zion–Mount Carmel Highway: the Park Service works to keep it open year-round, but snow, ice, rockfall or traffic sometimes close it.

Rockfall closes roads in any season. A rockfall shut part of the Zion–Mount Carmel Highway on 30 September 2026, and the Park Service reopened it fully on 9 October 2026. Walkers and cyclists may never use the tunnel on that road.

Some services shrink in winter. Zion Lodge and Watchman Campground stay open all year, the lodge with reduced services, while South Campground and Lava Point Campground close for the season.

Which Angels Landing lottery covers your travel month?

Angels Landing permits for a given month come from a seasonal lottery held about two months earlier, and Recreation.gov listed the dates below on 30 October 2026. Each window opens at 8 a.m. and closes at 11:59 p.m. Mountain Time.

A trip without a seasonal permit can still try the day-before lottery, which closes at 3 p.m. Mountain Time. No permits are issued for 19 to 22 April 2027, when the trail is under maintenance. The 2026 spring lottery ran in February instead of January, so the Recreation.gov listing is the date to trust. Our Angels Landing guide explains the fees and the hike itself.

Does the season change the Zion entrance fee?

The Zion entrance fee is the same in every month: $35 for a private car for seven days, $30 for a motorcycle and $20 a person on foot or by bicycle. Cards are preferred and cash is accepted. Zion is on the 2026 list of eleven parks that charge visitors from abroad $100 a person aged 16 or over on top. Two adults from abroad in one car pay $235 in any season.

Fee-free days do not help a visitor from abroad. Since 2026 they apply only to US citizens and residents, and 11 November is the last one of 2026. The 2027 list had not been published by 30 October 2026. Our guide to national park fees for international visitors covers the $250 annual pass that replaces both charges.

The clock moves with the season too. Utah is on Mountain Time and observes daylight saving time, which ended on 1 November 2026 and resumes on 14 March 2027. Between those dates Zion keeps the same time as Arizona, which stays on standard time all year; from 14 March 2027 it is one hour ahead.
