Spring is Yellowstone's season of new life. From mid-April through early June, the snow pulls back, the roads reopen one by one, and the park fills with newborn wildlife. Bison calves wobble beside their mothers, bears come out of their dens hungry, and waterfalls swell with snowmelt. It's one of the best times of year to see animals, and it comes with smaller crowds than summer.
Spring is also the park's most unpredictable season. Here's what to expect, how to prepare, and why a guided tour makes it easier.
A tour we think you'll love
The Best of Yellowstone
What you'll see
Baby animals. Bison calves, nicknamed "red dogs" for their orange coats, start arriving in April. Elk calves follow in late May and June, along with pronghorn fawns and bighorn lambs.
Bears. Grizzly and black bears leave their dens in spring and spend their days searching for food in open valleys. It's one of the best times of year to watch them from a safe distance.
Wolves. Packs are tied to their dens while raising pups, which can make their movements easier for experienced trackers to predict.
Roaring waterfalls. Snowmelt sends rivers to their peak in late May and June. The Lower Falls of the Yellowstone River, more than 300 feet tall, is at its loudest and most powerful.
Returning birds. Sandhill cranes, bald eagles, ospreys, and waterfowl return to the park's rivers and lakes.
What you'll experience
Spring weather can change by the hour. Days often range from the 30s to the 60s °F, and snow can fall well into May and even June. One afternoon might be sunny and mild; the next morning, the meadows may be white again.
The park opens in stages. Roads on the west and north sides of the park usually open in mid-April, with the east and south entrances following in May and high passes like Dunraven Pass opening around Memorial Day. Some lodges, restaurants, and visitor services don't open until May or June. Trails can be muddy or snow-covered, and boardwalks around the geyser basins may be icy in the early morning.
The reward is a quieter park. You'll share the geysers and wildlife viewing areas with far fewer people than in July.
How to prepare
Dress in layers. A synthetic or wool base layer, a warm fleece or puffy jacket, and a waterproof shell will cover most days. Bring a hat and gloves, even in late May.
Waterproof footwear. Expect mud, slush, and puddles on trails and in parking areas.
Sun protection. At 7,000 to 8,000 feet, the sun is strong, and snow reflects it. Pack sunglasses and sunscreen.
Binoculars and a camera with zoom. Spring wildlife is often visible but far away.
Patience and flexibility. Snowstorms, road closures, and wildlife on the road can change plans. Build some slack into your schedule.
Respect wildlife distance. Park rules require staying at least 100 yards from bears and wolves and 25 yards from all other animals. Mothers with young are especially protective.
Why a guided tour helps
Spring rewards people who know where to look and how to adjust. A guided tour takes the guesswork out of a season that changes daily.
We know where the animals are. Our guides follow wildlife activity, den sites, and recent sightings, and we bring spotting scopes so you can see a grizzly or a wolf in detail, not just as a speck on a hillside.
We handle the conditions. Road openings, weather, and closures change constantly in spring. We plan around them, so you don't spend your vacation checking road reports.
Safety comes first. Our guides carry CPR and Wilderness First Aid certifications and know how to view bears and other wildlife safely.
For families: Spring baby animals are a highlight for kids, and our guides turn every sighting into a story. We provide booster seats on request, and the pace is set around your family.
For friend groups: A private tour means your group decides how long to linger, whether that's an hour watching a bear on a hillside or extra time at the waterfalls for photos.
For active seniors: We do the driving, parking, and planning. You enjoy wildlife viewing from a comfortable van with large windows, with short walks and boardwalk strolls that fit your pace.
Plan your spring trip
Spring is the season for anyone who wants wildlife, waterfalls, and room to breathe. Our private multiday tours are designed around your group, so you can see Yellowstone as it wakes up without worrying about the details.
