Old Faithful Geyser

Approximately two million years ago, a supervolcano erupted in Yellowstone, forming a caldera, or basin. This entire area is part of the Yellowstone caldera from Old Faithful to Yellowstone Lake. Old Faithful Geyser is the star; however, this area offers more to see. Old Faithful is so predictable that it is one of the top things to see in Yellowstone National Park.

The Upper Geyser Basin is home to Old Faithful and the world’s largest concentration of geysers. The supervolcano keeps magna close to the surface, so visitors can see the water bubble and boil in the Upper Geyser Basin. The best way to explore this area is on foot, and there are a lot of paved hiking trails. In addition to several named geysers, visitors can see other geothermal features.

  • Hot Springs—Pools of hot water in an array of colors 
  • Fumaroles—A steam vent without a lot of water
  • Mudpots—Hot sulfuric acid breaks the rock into a smelly clay that bubbles on the surface.Tip: The approximate geyser eruption times for Old Faithful, Castle, and Grand geysers are posted in the Old Faithful Visitor Education Center and the lodges in the area. 

Old Faithful Inn

Opening its doors on June 1, 1904, Old Faithful Inn is made of local forest products. Architect  Robert Reamer wanted to bring the forest indoors. Old Faithful Inn is an Architectural landmark and one of the top notable buildings in the U.S. It’s seven stories tall and is the largest log cabin hotel in the world. Inside, the lobby rises to the roof's peak and offers several dining venues. 

The Old Faithful Inn is the most requested lodge inside Yellowstone National Park. Reservations are tough to secure, though visitors can walk through the building or reserve dinner in its dining room. Free tours are offered during the summer season. 

Grand Canyon of Yellowstone

Yellowstone National Park boasts a canyon more than 1,000 feet deep. In addition, this Grand Canyon has a pair of waterfalls, which is a must-see in the National Park. The 308-foot Lower Falls and the 109-foot Upper Falls are spectacular and popular spots in Yellowstone. 

The easiest way to see the Grand Canyon of Yellowstone is by driving the North Rim Drive or the South Rim Drive. Both are good viewing choices. It's over 20 miles long and over 4,000 feet wide. Both rim drives feature numerous pull-outs for viewing, like Artist Point and Grand View. Keep a lookout for osprey and other birds of prey that frequent the area.

Top Things To Do at Yellowstone Lake

As the largest high-elevation lake in North America, Yellowstone Lake is one of the best areas to fish in Yellowstone National Park. There are even fishing charters to take anglers to all the best spots. Another summertime favorite activity is a boat cruise on Yellowstone Lake. 

The grand, historic Lake Yellowstone Hotel opened in 1891. It remains the oldest hotel in the National Park Service. As the most luxurious property in Yellowstone, its rooms cater to adults. There is a free tour of the property available during the summer months. Like most lodging areas, the Lake Village also offers family-friendly cabins. Camping is also available nearby.

Some visitors enjoy the geothermal features, while others want to see animals. Yellowstone National Park offers some of the best animal viewing in the U.S. These are Yellowstone's most common wildlife species. 

  • Bison
  • Moose
  • Elk
  • Grizzly Bear 
  • Black Bear
  • Wolf
  • Bighorn Sheep
  • Mule Deer
  • Coyote
  • Pronghorn
  • Pika
  • Marmot

For the best wildlife viewing, we recommend Hayden Valley or Lamar Valley, both in the eastern portion of the park. Dawn and dusk are the best time for spotting wildlife, and binoculars are helpful. Guided tours are also popular. Check in with Park Rangers for the latest wildlife sightings. They know where animals frequent and are up-to-date on bear jams or traffic caused by a bear sighting. 

Remember, wildlife is unpredictable, so visitors should stay 25 yards away from all wildlife in Yellowstone. For bears and wolves, visitors should stay 100 yards away. 

Mammoth Hot Springs

In the Northwest corner of Yellowstone National Park, visitors can see the best-protected travertine-depositing hot springs in the world. Hikers can explore the terraced limestone at Mammoth with a series of overlooks and boardwalks. Mammoth offers offers more than the hot springs. This area houses the headquarters of the park and the site of Fort Yellowstone, constructed by the U.S. Army. 

After Yellowstone’s creation in 1872, poachers and rogue campers used the area illegally. The U.S. Army patrolled the area for 32 years, creating Fort Yellowstone as its headquarters. 

Top Things To Do at Mammoth

  • Tour the Albright Visitor Center 
  • Walk through Historic Fort Yellowstone 

The Mammoth area is at a lower elevation, so it is open year-round.
