Spring Wildlife in Yellowstone & Grand Teton: April–May Guide
Spring wildlife in Yellowstone and Grand Teton is one of the most exciting times to visit the Greater Yellowstone Ecosystem. As winter loosens its grip, the landscape transforms—roads reopen, wildlife becomes active, and new life begins across the valley.
If you’re planning a visit, April and May offer a rare window where fewer crowds, active animals, and dramatic seasonal changes all come together.
Park Openings: The Season Begins
Grand Teton National Park is accessible year-round, but spring marks the return of full access beginning May 1.
Yellowstone National Park begins its phased openings throughout April and May, with the South Entrance from Jackson opening on May 8, 2026—one of the most direct and scenic routes into the park.
Why visit during this time?
- Fewer crowds compared to summer
- Wildlife is highly active
- Landscapes shift daily from snow to green
Early season is a local favorite—and for good reason.
Baby Animal Season in Yellowstone & Jackson Hole
Spring is the season of new life, and wildlife viewing becomes especially rewarding.
Across Yellowstone and Grand Teton, you may see:
- Elk calves taking their first steps
- Bison calves (“red dogs”) across open flats
- Moose calves tucked into willow thickets
- Wolf pups born in April, hidden safely in dens
- Bear cubs emerging alongside their mothers
This is one of the most dynamic times in the ecosystem—but also one of the most sensitive. Wildlife is active, protective, and constantly moving.
Wildlife Highlights
Spring wildlife in Yellowstone and Grand Teton offers a wide range of sightings.
Wolves
April marks the arrival of pups. While they remain hidden, adult wolves are active hunting and traveling—making this a prime time for wolf watching.
Elk
Elk migrate off the National Elk Refuge and spread throughout the valley. Calving season begins in late May.
Bison (Buffalo)
Highly active in spring, often seen along roads and open landscapes. Calves are easy to spot with their bright orange coats.
Bears
Grizzly and black bears emerge from hibernation, often seen feeding on early vegetation or winter-killed carcasses.
Moose in the Valley
Moose remain one of Jackson Hole’s most iconic—and most vulnerable—species.
Recent surveys counted 66 moose in Teton County in 2025, highlighting ongoing population challenges.
Spring is one of the best times to spot them as they browse willows along rivers and wetlands, often with calves hidden nearby.
The Return of the Birds
Spring migration fills the skies and wetlands with life.
- Bald eagles and ospreys return to nest
- Sandhill cranes arrive in the valley
- Waterfowl fill rivers and ponds
- Songbirds bring back the sounds of spring
Birding in April and May can be spectacular across the region.
Caving & Hidden Landscapes
As snow melts at lower elevations, access to caves and unique geological features improves.
Spring offers a short window to explore these lesser-known areas before peak summer crowds arrive.
