Yellowstone National Park, spanning Wyoming, Montana, and Idaho, was established by Congress in 1872 as the world’s first national park. Today it covers about 2.2 million acres (roughly the size of Rhode Island plus Delaware). Yellowstone is famous for its geothermal wonders – about half of the world’s active geysers and over 10,000 thermal features lie here. These include iconic sites like Old Faithful Geyser and the brilliantly colored Grand Prismatic Spring, all powered by Yellowstone’s volcanic hot spot. UNESCO notes Yellowstone “showcases significant geological phenomena” and is a unique “manifestation of geothermal forces, natural beauty, and wild ecosystems”. In short, Yellowstone’s dramatic landscapes and wildlife attract adventurers from around the globe.
Historic Significance. For history buffs, Yellowstone’s story is as compelling as its scenery. The area was long used by Native American tribes and eventually explored by 19th-century surveyors. After the famous Hayden Geological Survey of 1871 documented its wonders, Congress passed the Yellowstone Protection Act, and on March 1, 1872 President Ulysses S. Grant signed the park into law. This made Yellowstone the very first national park in the world. In 1978 Yellowstone (along with Mesa Verde) became one of the first U.S. sites inscribed on the UNESCO World Heritage List. Today the park is celebrated as an “intact large ecosystem” where natural processes continue largely undisturbed.
Yellowstone’s hydrothermal basins and snow-covered terraces offer otherworldly views. In winter, steam rising from Mammoth Hot Springs (pictured above) contrasts sharply with the snow. Geyser Basins: Yellowstone’s central geyser basins contain spouting geysers, bubbling mudpots, and rainbow hot springs. Old Faithful is the most famous geyser, erupting on a roughly 90-minute schedule. Nearby basins (like Upper, Midway, and Lower Geyser Basins) include the colorful Grand Prismatic Spring and the powerful but unpredictable Steamboat Geyser. In fact, UNESCO notes Yellowstone has “more than 10,000” thermal features and about “300 geysers” – roughly two-thirds of all geysers on Earth.
Wildlife and Ecosystem
Yellowstone’s vast wilderness supports abundant wildlife. The park is home to large herds of bison and elk, which often graze in open valleys (like Hayden and Lamar Valleys). Grizzly bears, black bears, wolves, and mountain lions also roam the forests and meadows. According to park authorities, Yellowstone offers visitors “unparalleled opportunities to observe wildlife in an intact ecosystem”. In fact, UNESCO highlights Yellowstone as “one of North America’s foremost refuges for rare plant and animal species,” where grizzlies and wolves are intensively studied. The Yellowstone bison herd is especially notable – it’s the only continuously free-ranging wild bison population left from the pre-settlement Great Plains. Birdlife is rich too: trumpeter swans, bald eagles, ospreys, and herons are common around lakes and rivers. (Late spring and early summer migrations bring colorful songbirds and waterfowl.)
Top Attractions and Activities
One of Yellowstone’s most spectacular sights is the Grand Canyon of the Yellowstone. This deep, colorful gorge is carved by the Yellowstone River and highlighted by the Lower Falls (a 308-foot waterfall). Hikers on the South Rim can reach viewpoints like Artist Point to look straight down into the canyon. Aside from the canyon and falls, key attractions include:
- Old Faithful Geyser: Yellowstone’s best-known geyser, erupting roughly every 60–100 minutes. The adjacent visitor center and historic Old Faithful Inn are must-see.
- Grand Prismatic Spring: The park’s largest hot spring, famous for its vivid red, orange and blue rings. A short hike to the Grand Prismatic Overlook or a walk along the boardwalk at Midway Geyser Basin provides great views.
- Mammoth Hot Springs: A vast terrace of travertine formed by limestone deposits. Walk the wooden trails that wind through the steaming, multi-colored ledges.
- Lamar and Hayden Valleys: Open meadows renowned for wildlife viewing. Early morning here offers sightings of bison herds, elk herds, and predators (wolves and bears) in the distance.
- Yellowstone Lake: North America’s largest high-elevation lake (7,733 ft). Drive along its shoreline or take a boat tour; the lake area is beautiful at sunrise.
- Norris Geyser Basin: The hottest and oldest thermal area, with Steamboat Geyser (the world’s tallest geyser) and other active features.
- Hiking and Tours: Popular trails include Mt. Washburn (great overlook), Mystic Falls, and Artist Point. During winter, guided snowcoach or snowmobile tours allow access to Old Faithful and other sites.
Visitors can also enjoy ranger-led programs at visitor centers, horseback riding excursions, and scenic drives (the loop road). Historic features like the Old Faithful Inn (built 1904) and Roosevelt Lodge maintain Yellowstone’s pioneering spirit.
Planning Your Visit
Best Time to Visit: Summer (July–August) offers full park access, lush scenery and warm nights, but expect crowds and booked lodgings. Shoulder seasons (late spring and early fall, e.g. May–June or September) can be ideal: most roads are open and the weather is mild, but there are fewer visitors. Fall also brings elk rutting and autumn colors. Winter (Dec–Feb) turns Yellowstone into a snow-covered wonderland: most roads close to wheeled vehicles, but snowmobile and snowcoach tours operate on key routes. (If you plan a winter trip, book well in advance for guided tours and resort lodging.)
Lodging & Camping: Yellowstone has a mix of historic lodges and modern cabins (Old Faithful Inn, Lake Yellowstone Hotel, Mammoth Hot Springs Hotel, etc.), but rooms fill up years in advance during high season. Be sure to reserve any in-park lodging or campsites months (even a year) ahead of your trip. If Yellowstone’s hotels are full, nearby gateway towns like West Yellowstone, MT (west entrance) and Gardiner, MT (north entrance) offer many hotels and amenities just outside the park. Camping options range from primitive backcountry sites (permit required) to developed campgrounds (reservable online). Note: “Park campgrounds are reserved and full far in advance—plan ahead for a successful visit!”.
Entrance Fees: All visitors must purchase a park pass for entry. As of 2023, a 7-day vehicle pass is $35, and a 7-day individual/foot pass is $20. An annual Yellowstone pass (7-day entry anytime) is $70, while the America the Beautiful annual park pass (covers all U.S. national parks) is $80. (All passes can be bought online or at entrance booths.) Travel Tip: If entering via the South Entrance, remember Grand Teton NP has its own entrance fee.
| Pass Type | Price (USD) |
| 7-day private vehicle pass | $35 |
| 7-day individual/hiker pass | $20 |
| Yellowstone 7-day annual park pass | $70 |
| America the Beautiful annual pass (all NPs) | $80 |
Practical Tips:
- Gear Up: Pack layered clothing (weather can change fast) and good walking shoes or hiking boots. Bring binoculars and a camera for wildlife and scenic views.
- Stay Safe: Yellowstone’s wonders come with hazards. Always stay on boardwalks and trails in thermal areas – the hot springs are deep and can be deadly. Keep a safe distance from wildlife: at least 100 yards (91 m) from bears and wolves, and 25 yards (23 m) from all other animals. Never feed or approach animals. Carry bear spray on hikes, and make noise (talk or sing) to avoid surprising bears.
- Wildlife Jams: Pull off in designated turnouts if you see wildlife on the road. Don’t block traffic; stay in your car if watching animals from a roadside.
- Respect the Park: Pack out all trash and avoid damaging vegetation. Natural objects (rocks, plants, etc.) are protected – leave them where you found them.
- Park Hours: Most Yellowstone entrances operate 24/7 in summer; some winter closures apply. Check the NPS website for current road and facility status before your visit.
- Cell Service: Coverage is very limited (mostly in Mammoth/Gardiner, Canyon area). Download maps and information beforehand.
