About Yellowstone National Park
Yellowstone National Park is America's first and most famous national park, established in 1872 across 8,983 km2 of volcanic plateau in Wyoming, Montana, and Idaho. While world-renowned for its geothermal features, including Old Faithful geyser and the Grand Prismatic Spring, Yellowstone is equally significant as a premier wildlife destination. The park supports the largest concentration of large mammals in the lower 48 states, including grizzly bears, gray wolves, bison, elk, moose, and mountain lions. The reintroduction of gray wolves in 1995 is one of conservation's greatest success stories, triggering a trophic cascade that transformed the park's entire ecosystem. The Lamar Valley, often called "America's Serengeti," offers outstanding wolf and bear viewing, particularly during early morning and evening hours. Winter visits offer a unique experience, with wolves hunting in deep snow and bison steaming in geothermal areas. The park also hosts the largest free-roaming bison herd in the United States, with approximately 5,000 animals. Over 300 bird species have been recorded within the park boundaries.

Real experiences from wildlife travellers
Wolves in the Lamar Valley at dawn
Watched the Junction Butte wolf pack hunt elk in deep snow through a spotting scope. Grizzly bear with two cubs near Tower Junction. Bison everywhere, crossing roads and steaming in the thermal areas.
Winter is incredible for wolves and far fewer tourists. Bring a spotting scope or join a wolf-watching guide in the Lamar Valley. Yellowstone Forever runs excellent wildlife programs.
