Discover geothermal activity, a geyser basin, the small Grant Village and more natural attractions from the western inlet of Yellowstone Lake.
Even among Yellowstone National Park’s myriad natural wonders, West Thumb stands out. The extension of Yellowstone Lake is a caldera within a caldera it was created by a large volcanic eruption about 150,000 years ago. To understand how it earned its name, look at a map of Yellowstone Lake. The body of water is shaped like a human hand and West Thumb serves as its first digit.
Stop at the West Thumb Information Station, a historic ranger station built in 1925. Before exploring the adjacent geyser basin, learn more about the area through informative displays.
Investigate the distinctive Fishing Cone. Early visitors discovered they could stand next to this shore-side geyser, hook a fish in the chilly lake and then cook it in the hot spring. Although fishing is now prohibited, it remains a remarkable sight.
Stop at the brilliantly blue Abyss Pool and Black Pool. Don’t be fooled by the serene appearances of the hot springs they’ve both erupted fairly recently.
Take a break at Grant Visitor Centre. The centre was named in honour of President Ulysses S. Grant, who signed the bill to create Yellowstone National Park in 1872. Learn about the park's historic fires of 1988 and the West Thumb area through a series of exhibits. Grant Village offers a large lodge and campsites for overnight visitors.
Use West Thumb as a jumping-off point to explore Yellowstone Lake, the largest body of water within Yellowstone National Park. From the lake’s shores, admire stunning views of West Thumb and the Absaroka Mountains. Hike along the Scenic Lake Overlook or embark on an overnight backpacking excursion at one of the many wilderness trailheads.
Although geothermal activity takes centre stage here, the West Thumb area is also home to a variety of wildlife. In the spring, watch for grizzly and black bears. Elk and their newborn calves are a common sight in May and June. Look for bald eagles and osprey diving into Yellowstone Lake to catch fish.
