Yellowstone
The World's First National Park
On March 1, 1872, Yellowstone was established as the first national park, offering everyone the chance to experience its unique hydrothermal and geological features. Spanning 2.2 million acres, the park provides unparalleled opportunities to observe wildlife in its natural habitat, explore geothermal areas home to about half of the world’s active geysers, and marvel at geological wonders like the Grand Canyon of the Yellowstone River.

Yellowstone National Park, established in 1872, is the first and oldest national park in the world. Spanning across parts of Wyoming, Montana, and Idaho, it covers over 2.2 million acres of diverse landscapes, including geothermal wonders, deep canyons, lush forests, and sprawling meadows.
Here are some highlights of Yellowstone:
Geothermal Features: Yellowstone sits atop a supervolcano, which fuels many geothermal features, including hot springs, mud pots, fumaroles, and geysers. Old Faithful, one of the park's most famous geysers, erupts with remarkable regularity every 90 minutes.
Grand Prismatic Spring: Known for its striking, colorful appearance, Grand Prismatic Spring is the largest hot spring in the U.S. and the third-largest in the world. Its vibrant hues come from thermophilic bacteria and mineral-rich water.
Wildlife: The park is home to an impressive range of wildlife, including bison, elk, grizzly and black bears, gray wolves, bighorn sheep, and bald eagles. Wildlife viewing is a major draw for visitors, especially in Lamar Valley and Hayden Valley.
Scenic Waterfalls and Lakes: Yellowstone Lake, one of the largest high-altitude lakes in North America, is a highlight. The Grand Canyon of the Yellowstone, with its waterfalls like Lower Falls, provides awe-inspiring views of layered rock formations and dramatic landscapes.
Recreational Activities: The park offers numerous activities such as hiking, fishing, kayaking, and camping. In winter, visitors enjoy snowshoeing, snowmobiling, and cross-country skiing.
History and Conservation: Yellowstone is a place of deep historical and environmental significance. The park helped set the precedent for conservation efforts worldwide and is part of the Greater Yellowstone Ecosystem, one of the last intact temperate ecosystems.
Each season in Yellowstone offers a unique experience, from summer’s bustling trails and wildlife sightings to winter’s serene, snow-covered landscapes.
