Overview

Mammoth Hot Springs, Wyoming Tours

Mammoth Hot Springs, located in the northern part of Yellowstone National Park, is a one-of-a-kind geological wonder. Unlike the fiery geysers of the Old Faithful area, Mammoth is a sprawling complex of hot springs on a hill of travertine. The colorful, cascading terraces are formed as hot, acidic water from deep within the earth rises to the surface, dissolving limestone on its way up. As the water cools and evaporates, it deposits the dissolved minerals, creating a constantly shifting, ethereal landscape of chalky white, orange, and brown formations.

A visit to Mammoth is a journey into an otherworldly landscape that changes with every season. It serves as both a natural marvel and the historic headquarters of the park, with the iconic Fort Yellowstone located nearby. As a key stop on many cruisetours, it provides a fascinating glimpse into the unique geothermal forces that shape the park and offers a perfect blend of natural beauty, historic context, and accessible exploration via its extensive boardwalk system.

Top Things to Do in Mammoth Hot Springs, Wyoming

Explore the Lower Terraces

Walk the boardwalks of the Lower Terraces to get up-close views of the most active and colorful features. This network of trails winds past beautiful formations like the Minerva Terrace and Palette Spring, offering stunning photo opportunities.

Tip: The Lower Terraces are easily accessible from the main parking area and are best explored on foot. Be sure to stay on the boardwalks to protect both the delicate formations and your own safety.

Drive the Upper Terraces Loop

Take a scenic drive on the one-way Upper Terraces Loop, which provides a different perspective of the geothermal activity. The road takes you past features like the Angel Terrace and the impressive Orange Spring Mound.

Tip: This drive is not suitable for RVs or large vehicles. There are pullouts along the way to stop and take photos.

Visit the Albright Visitor Center

Located in the historic Fort Yellowstone area, the Albright Visitor Center offers a wealth of information about the park's history, wildlife, and geology. The building itself is a former U.S. Army bachelor officers' quarters, adding to its historic charm.

Tip: Talk to a park ranger to get up-to-date information on trail conditions, wildlife sightings, and ranger-led programs.

Spot Elk Roaming the Grounds

The Mammoth Hot Springs area is famous for its abundant wildlife, particularly elk. Herds of elk often graze on the lawns of the historic district and can be seen right in the town of Mammoth Hot Springs itself, adding to the unique atmosphere.

Tip: Maintain a respectful distance from all wildlife, especially elk, which can be unpredictable. Never try to touch or feed them.

Walk the Boardwalk to Liberty Cap

At the northern end of the Lower Terraces, you'll find Liberty Cap, an unusual and striking cone-shaped hot spring formation. A short, easy walk on the boardwalk takes you to the base of this prominent landmark.

Tip: Liberty Cap stands at 37 feet tall and is a popular photo spot due to its unique shape and size.

Tour Fort Yellowstone

Explore the Fort Yellowstone Historic District, a collection of preserved military buildings. The U.S. Army was brought in to protect the park from poachers and vandalism in the late 19th century, and their presence left a significant mark on the park's history.

Tip: Many of the buildings, including the former Guard House and the chapel, are still in use as park headquarters and other facilities.
