Steamboat Geyser, Wyoming
Steamboat Geyser, situated in the Norris Geyser Basin of Yellowstone National Park, is the tallest active geyser in the world, capable of shooting water between 300 and over 400 feet into the air. Renowned for its unpredictable major eruptions and prolonged, powerful steam phases, its activity increased markedly from 2018 to 2021.
Tucked within the Norris Geyser Basin, Steamboat Geyser stands as the world’s tallest active geyser, with major eruptions blasting water over 91 m into the air. Only Waimangu Geyser, New Zealand, has reached greater heights—though not in over a century. In the recorded history of Yellowstone National Park, just two other geysers—Excelsior Geyser in Midway Geyser Basin and Sapphire Pool in Biscuit Basin—have surpassed it in size.
Major Eruption
A major eruption of Steamboat Geyser is an unforgettable spectacle. Water first surges from two vents at varying heights before suddenly blasting more than 91 m into the air. Sheets of water cascade down the slope, gathering into torrents that rush back into the vents, carrying mud, sand, and rocks that are repeatedly hurled skyward. Everything nearby becomes coated in a shimmering layer of silica.
Large amounts of eruption debris often accumulate around the geyser. Sometimes, mature Lodgepole Pine trees have been snapped by the force of the downpour, uprooted, and swept away by the powerful outflow, while boardwalks at the base of the hill have been buried under the geyser’s deposits.
The water phase of a major eruption can last anywhere from 3 to over 40 minutes. After the water subsides, the geyser enters an intense steam phase that can continue for hours or even days. The roaring sound is so loud that conversation nearby becomes difficult.
Minor Eruption
Steamboat Geyser most commonly produces minor eruptions, which typically rise 2–12 m and last 1–4 minutes, with intervals as short as 2–5 minutes. The taller and longer of these bursts often raise anticipation of a major eruption, as water shoots from both the larger north vent and the smaller adjacent vent—yet the activity usually subsides quickly. The recent major eruption occurred on 27 February 2026 and lasted 57 days.

Tallest Geyser
Steamboat Geyser is the tallest active geyser in the world. It features two vents-the northern and southern-positioned about 6.1 m apart. The north vent produces the highest water jets, while the south vent generates shorter columns.
Before 1904, Waimangu Geyser in New Zealand produced even taller eruptions, reaching up to 490 m. However, a landslide that year altered the local water table, and the geyser has remained inactive ever since. Within Yellowstone, Excelsior Geyser in the Midway Geyser Basin and Semi-Centennial Geyser near Roaring Mountain were once reported to rival Steamboat, with eruptions reaching around 91 m. Today, Excelsior functions as a hot spring, having not erupted since 1985, while Semi-Centennial has been dormant since its only recorded eruption of that magnitude in 1922.

How to reach Steamboat Geyser, Wyoming
Steamboat Geyser is located in the Norris Geyser Basin of Yellowstone National Park, Wyoming, along the western arm of the Grand Loop Road. Access is via a short, level walk from the Norris parking lot, which is approximately 20 minutes from Canyon Village. The area is open year-round, though roads close in winter.
