Yellowstone is open for the 2026 season! The West Entrance and North Entrance are welcoming visitors now, with more roads opening throughout May. Spring is prime time in the park — grizzlies are emerging from hibernation, bison calves are hitting the ground, and Lamar Valley wolves are active. Geothermal steam columns rise dramatically in the cool air, and the waterfalls are running at full force. Come explore — our guides know exactly where to take you.
