Anemone Geyser

Small twin geyser with frequent bursts and a dramatic drain

InsideYellowstone National Park

Overview

Anemone Geyser is a small but lively pair of pool-type geysers—Big Anemone and Little Anemone—on Geyser Hill in the Upper Geyser Basin, a short boardwalk stroll from the Old Faithful hub. It’s famous for its quirky “inhale” after each burst: the pool audibly drains back down, a behavior that helped inspire its anemone-like name.

What You’ll See

Expect short, frequent bursts from Big Anemone separated by just a few minutes, often followed by Little Anemone chiming in more erratically. The play is modest—jets just a few feet high—but the rhythm and the dramatic post-eruption drain make it one of the basin’s most entertaining quick stops. Listen for gurgles as the water retreats.

Behavior and Geology

These are classic fountain/pool geysers in siliceous sinter with intertwined plumbing. When one is extra active, the other often calms, a back-and-forth that showcases how connected geysers can be here. Activity can also shift with basin-wide cycles and seasonal changes. Water temperatures are scalding, around the boiling point for the elevation.

Getting There and Services

You’ll encounter Anemone along the Upper Geyser Basin boardwalk loop from the Old Faithful area. Park in the main Old Faithful lots and walk in. Restrooms, food, and shops are clustered around the Old Faithful visitor hub—not at the geyser itself. Boardwalk segments can occasionally close for repairs; follow posted signs.

Best Time to Visit

Early morning for thinner crowds and easy parking.
Late afternoon light makes the ripples and the “drain” easier to see.
Because it erupts often, lingering just a few minutes usually rewards you with a show.

Nearby Highlights

You’re in the heart of the Upper Geyser Basin: Lion Group, Beehive, Grand/Turban, and Castle are all within a broader wander. It’s easy to stack several marquee features into one loop.

Safety and Wildlife

Stay on the boardwalks—ground here is thin and the water can cause severe burns. Bison and elk sometimes pass through; give them ample space and never approach.

Pros

Frequent, short-interval eruptions—rarely a long wait
Distinctive draining action that’s fun to watch up close

Cons

Small compared to Yellowstone’s headline geysers
Crowded boardwalks at peak Old Faithful times

Tips

Linger 10 minutes and you’ll likely catch at least one eruption.
After a burst, watch carefully—the rapid draining is the real show.
Go early or late afternoon to beat crowds and for better light.
Park at Old Faithful and walk the Geyser Hill loop; no restrooms at the feature.
Give bison and elk plenty of space if they wander through the basin.
