Fountain Geyser

Overview

Fountain Geyser is the headline act of the Fountain Paint Pot area in the Lower Geyser Basin. It’s a classic fountain-type geyser: water erupts in powerful, intermittent jets from a broad pool rather than a single thin column. It sits near Firehole Lake Drive and is separate from the larger, more sporadic Great Fountain Geyser.

What to Expect

When Fountain goes, it puts on a sustained show—typically around 30 minutes—with repeated bursts that often reach 40–50 feet and can top out around 75–80 feet. Intervals between eruptions commonly range from roughly 4 to 15 hours and can shift year to year. Now and then it enters a prolonged “wild-phase,” with shorter, lower bursts that can continue for days to weeks.

Nearby Context

Morning Geyser, immediately adjacent, is actually larger but is inactive in most years, making Fountain the reliable star here. This is a great stop to pair with other sights along Firehole Lake Drive, including the separate Great Fountain Geyser.

Visiting Tips

• Timing is everything: intervals vary, so plan extra time and check recent activity reports with rangers or at visitor centers.
• Wind can swing scalding spray across the boardwalk—bring a light shell and protect camera gear.
• Early or late in the day improves photography and trims the crowds.

Safety & Etiquette

Stay on the boardwalk; the thermal ground is fragile and dangerous. Give wildlife space—at least 25 yards from bison and elk, and 100 yards from bears and wolves.

Amenities

Restrooms are available in the Fountain Paint Pot area (typically vault toilets). Use them when you see them; facilities aren’t at every stop.

Best Time to Visit

Aim for early morning or late afternoon for softer light, fewer people, and less midday shimmer. Because predictions are broad here, build flexibility into your plan and use recent ranger updates to decide whether to wait or circle back later.
