Best Time to Visit Yellowstone National Park: Month by Month Guide [2026]
Month-by-month weather, crowds, prices, and the best time to book
Where
The best time to visit Yellowstone is late May through mid-June and mid-September to early October. These months offer mild weather, fewer crowds, great wildlife viewing, and lower prices than the busy summer peak.
When Is the Best Time to Visit Yellowstone?
The best time to visit Yellowstone is late spring (late May to mid-June) and early fall (mid-September to early October), when temperatures are comfortable, wildlife is active, and crowds are much lighter than during the July and August peak. Most travelers find these shoulder months the sweet spot for Yellowstone’s famous geysers, epic hiking, and wildlife watching, without the packed parking lots and $450/night hotel rates. If you want the broadest choice of flights and hotels, you can search flights on Travorio and filter by your preferred dates.
Summer draws the biggest crowds to Yellowstone, but it's not the only option. The trick is timing: late spring delivers roaring waterfalls and bison calves, while early fall offers bugling elk and golden aspens. Winter is cold but magical for snowshoeing and wolf tracking. Every season brings its own perks, so when to visit Yellowstone depends on your priorities, whether that's seeing baby bears, avoiding crowds, or snagging a $98 lodge room in October.
Best Time to Visit Yellowstone National Park: Month-by-Month Guide
Yellowstone’s seasons are dramatic and each month has its own personality. Winter (December to March) transforms the park into a snowbound wilderness. Expect temperatures between 0°F and 25°F (-18°C to -4°C), with snow piling up to 10 feet in spots. Only the north and northeast entrances (Gardiner and Cooke City) stay open to cars, and the rest of the park is only accessible by snowcoach or snowmobile. Most hotels inside the park close, except for Mammoth Hot Springs Hotel (open December to early March, rooms from $185/night). Winter is your best bet for solitude and wolf watching tours, but you’ll need to dress for Arctic conditions.
Spring (April to early June) is unpredictable, snow can linger, and some roads don’t open until late April or even mid-May. Temperatures range from 20°F mornings to 55°F afternoons. By late May, bison calves appear and waterfalls are at full force from snowmelt. Crowds are low until Memorial Day. You’ll have the best luck with hotels in West Yellowstone or Gardiner, where rates average $110-$160/night in May.
Summer (late June through August) is Yellowstone’s busiest season by a mile. Days are warm (60-78°F, or 16-26°C), nights are cool, and every road, trail, and visitor center is open. Plan for lines at Old Faithful, packed boardwalks, and $350+ hotel rates inside the park. Early July brings wildflowers and the best hiking weather. If you want to see the park’s classic sights, summer is your window, but book at least six months ahead.
Fall (September to early November) is my personal favorite. The aspen and cottonwood trees turn gold, elk bugle in the valleys, and the first snows dust the mountains by late September. Temperatures slide from 60°F (15°C) in early September to freezing by late October. Crowds thin out, and you can snag a room at the Old Faithful Snow Lodge for $125/night midweek. By mid-October, many park roads and lodges start to close, so check the NPS website for updates.
Peak Season vs Shoulder Season
Peak season in Yellowstone means July and August, when nearly half of the park’s annual 4 million visitors arrive. Hotel rates inside the park hit $450/night for Old Faithful Inn and sell out months in advance. Flights to Bozeman or Jackson can double in price, with round-trip tickets from Chicago running $600+ in July compared to $240 in October or May. Traffic on the Grand Loop Road crawls along at 25 mph on busy weekends, and parking at hot spots like Grand Prismatic Spring fills up by 8 a.m.
The shoulder seasons, late May to mid-June and mid-September to early October, offer a much better experience for most travelers. You’ll still have access to the main roads and sights, but hotel rates drop to $110-$160/night in gateway towns like Gardiner or Cody. Even in-park lodging like Canyon Lodge offers rooms for $175 versus $410 in July. Flights are also cheaper: Salt Lake City to Bozeman can be as low as $120 one-way in May.
If you’re looking for value, avoid the summer holidays (Memorial Day, 4th of July, Labor Day). These weeks see the highest prices and the longest lines. Spring and fall also mean fewer tour buses and a better chance at last-minute reservations. Families with school-age kids are often locked into summer, but if you have flexibility, late September feels like a local’s secret.
Winter is the true off-season. Yellowstone’s gateway towns offer rock-bottom hotel rates, $68/night at City Center Motel in West Yellowstone, and you can book last-minute. The tradeoff: only a handful of snow coaches and guides operate, and you’ll need to book those in advance if you want to see Old Faithful under snow.
Weather and Climate in Yellowstone National Park
Yellowstone’s weather is famously unpredictable. Elevations range from 5,300 feet in Gardiner to over 11,000 feet on the park’s peaks. That means even in July, freezing nights are common. Average July highs are 78°F (26°C) with lows around 41°F (5°C). By January, that drops to highs of 25°F (-4°C) and lows near 0°F (-18°C). Rainfall peaks in May and June, with 2.1 inches per month, then tapers off by late summer. Snow can fall in any month, but major storms usually hit from November to March.
Humidity is generally low year-round, though you might feel the chill in spring and fall when cold fronts roll in. There’s no ocean nearby, so you won’t get sea breezes or tropical storms. Instead, expect quick changes, sun, rain, and hail can all show up in a single day, especially in June and September.
Packing for Yellowstone means lots of layers. In summer, bring a down vest, rain jacket, and hat for cool mornings. Midweight hiking pants and moisture-wicking shirts are ideal. In spring and fall, you’ll want gloves, a warm beanie, and waterproof boots, the trails can be muddy or even snowy into June. For winter, you’ll need a serious parka, insulated pants, and snow boots rated to -20°F. Don’t forget sunglasses and sunscreen year-round, since high elevation means strong UV.
Most guides don’t mention that Yellowstone’s weather at Old Faithful can be 15°F warmer than at Lake Village or Dunraven Pass on the same day. If you’re planning a long hike, check the hourly forecast for your area, and bring a backup fleece in your daypack.
Events, Festivals, and Things to Do by Season
Yellowstone doesn’t have big music festivals or parades, but its seasonal wildlife events are legendary. In May and June, the best wildlife viewing season, bison and elk calves appear in Lamar Valley, and grizzly bears emerge from hibernation. Spring is also prime time for waterfall chasers, Lower Falls in the Grand Canyon of the Yellowstone is roaring with snowmelt. Most roads open by Memorial Day, and ranger programs restart in late May.
July and August are all about hiking, geyser watching, and family activities. Rangers offer daily talks at Old Faithful Visitor Education Center and free guided walks at Mammoth Hot Springs. The West Yellowstone Rodeo (June-August, tickets $20) is a local summer highlight. If you want to avoid the Yellowstone summer crowds, go to Norris Geyser Basin at sunrise, parking fills by 9 a.m. most days.
September is elk rutting season. You’ll hear bull elk bugling in Mammoth or Hayden Valley almost every morning, and photographers flock in to catch the action. Fall also means golden aspens, crisp air for hiking, and the annual Cody Wild West Spectacular musical (runs June-August, but September brings smaller crowds). Late-September sees several local food events in Gardiner and Cody, like the Gardiner Brewfest.
Winter is Yellowstone’s quietest season, but it’s magical for snowshoeing, cross-country skiing, and guided snowcoach tours to Old Faithful (around $140 per adult). The Christmas season brings torchlight parades in West Yellowstone and hot cocoa by the fire at Mammoth Hotel. You can also join Yellowstone Forever Institute’s wolf tracking workshops (January-February, $875 for three days, including guides and equipment).
How to Book Your Yellowstone National Park Trip
Booking a Yellowstone trip is easiest if you start with flights. Bozeman Yellowstone International Airport (BZN) is the most popular gateway, with nonstop flights from Delta (Minneapolis, Salt Lake City), United (Denver, Chicago), and Alaska Airlines (Seattle, Portland). Jackson Hole (JAC) is another option, especially if you want to combine Yellowstone and Grand Teton. You can search flights on Travorio and compare prices across dates and airlines.
For hotels, you’ll find a wide range from in-park lodges (book at least 6 months ahead for July/August) to motels in West Yellowstone, Gardiner, or Cody. If you want to lock in a good rate without a big upfront payment, Travorio’s Pay Later Hotels option lets you split the cost over four payments with Sezzle or PayPal Pay Later. This is especially useful if you’re booking a $1,200 multi-night stay during peak season. Check available options at Travorio Pay Later Hotels.
Crypto fans can pay with Bitcoin, Ethereum, or over 100 other cryptocurrencies on Travorio. Just select your preferred coin at checkout. This is handy for international travelers who want to avoid currency conversion fees.
Rental cars are essential for most Yellowstone trips. Book early if you’re arriving in July, as rates can spike above $130/day. In May, you’ll often find deals under $70/day. Most national chains (Enterprise, Hertz, Alamo) have desks at Bozeman and Jackson Hole airports. Reserve as soon as you book flights, and plan to enter the park early each day to beat the crowds.

Frequently Asked Questions
Common questions answered clearly and concisely
Most locals and repeat visitors say the best month to visit Yellowstone is September. You get crisp mornings (40-60°F), golden aspens, active wildlife, and far fewer tourists than in July. Hotel rooms drop from $410 in August to around $140-$190 per night, and you still have full access to the park’s roads and hiking trails.
October and April are the cheapest months for hotels and flights. Expect rates as low as $98-$135/night in gateway towns like West Yellowstone, and round-trip flights from LA or Denver can be under $200. Most in-park lodges close in winter, but gateway motels stay open and rarely fill up.
Late July and early August are the busiest and most expensive weeks, with peak crowds, $450/night hotel rates, and long lines at every major sight. Some travelers also find March and November challenging due to unpredictable weather, roads may close, and most park services are limited.
Rain peaks in May and June, with about 2.1 inches per month and frequent afternoon thunderstorms. July and August are drier, averaging 1.2-1.5 inches of rain, mostly in short bursts. Always pack a rain shell if you’re hiking in spring or early summer.
No, Yellowstone is far from the coast and does not experience hurricanes or monsoons. The main weather hazards are late-season snowstorms and summer thunderstorms, which can pop up quickly from June to September. Lightning is the main summer risk on exposed trails.
Mid-June to early July is great for families, most roads are open, ranger programs run daily, and you’ll see lots of wildlife, including baby bison and elk. Summer crowds are big, so plan early mornings and book hotels at least six months ahead. The West Yellowstone Grizzly & Wolf Discovery Center is open year-round and popular with kids.
Mid-September to early October offers cool weather, fall colors, and far fewer crowds, perfect for couples. You can find rooms at Old Faithful Snow Lodge for $125/night midweek, and take peaceful hikes or enjoy private wildlife watching in Lamar Valley at sunrise.
For July and August, book hotels six to nine months in advance, especially in-park lodges, which sell out quickly. May, June, September, and October offer more flexibility, but booking three to four months ahead still gets you the best rates. Flights typically drop in price three months out, but car rentals for summer should be reserved as soon as possible.
Always pack layers: a warm fleece, rain jacket, hat, and gloves, even in summer. Good hiking shoes, sunscreen, and a refillable water bottle are essential. Spring and fall require waterproof boots and extra warm clothes, while winter trips need a down parka and snow boots rated to -20°F.
Yellowstone sits in the United States, so international visitors will need a valid US tourist visa (B-2) unless they’re from a Visa Waiver Program country. Canadians and most Western Europeans can enter with ESTA authorization for up to 90 days. Always check the latest US State Department guidance before booking flights.
