Overview
Cliff Geyser is a small, characterful fountain geyser in Black Sand Basin, an outlying section of the Upper Geyser Basin near Old Faithful. It sits on the edge of Iron Creek, framed by a cliff-like rim of silica (geyserite) that gives the feature its name.
What you’ll see
When active, Cliff Geyser throws spunky bursts of water and steam about 15–40 feet high. A handy cue: the crater nearly fills with vigorously boiling water just before it goes. Eruptions can last roughly 30 minutes up to 3 hours, and in active phases you might catch 1–2 shows a day.
Eruption behavior (temperamental, but fun)
Intervals are famously inconsistent—anywhere from about 30 minutes to 18 hours—and the geyser can go quiet for weeks or even years. That unpredictability makes it a pleasant surprise when it’s on; if you arrive to a rapidly filling, boiling pool, stick around.
Getting there & on-site experience
A short, easy boardwalk loop (about a quarter mile) circles Black Sand Basin, with Cliff Geyser right along Iron Creek. There’s a small parking area, but don’t expect much else—treat this as a quick, scenic stop. If you need full services, Old Faithful Village is close by. Wind can swing steam and spray across the boardwalk, so mind your camera and stay put on the planks.
History & geology
Named by A. C. Peale during the 1872 Hayden Expedition for its cliff-like sinter rim and creekside perch, Cliff Geyser is a classic product of Yellowstone’s hydrothermal plumbing. Silica-rich water deposits that crisp white rim over time, while constrictions below trap and flash water into steam that powers its lively bursts.
Nearby highlights
Black Sand Basin packs a lot into a small area: Emerald Pool’s vivid greens, near-continuous activity at Spouter Geyser, and the colorful Rainbow Pool. Sunset Lake, a broad, shallow pool, has even shown rare surges in the past.
Best time to visit
- Early morning: moody, photogenic steam and fewer people.
- Midday: clearer views of the water jets when the air warms.
- Weekdays are typically calmer; plan extra time if you see the crater filling and boiling—showtime may be imminent.
