Fountain Paint Pot Nature Trail

Overview

A greatest-hits stroll through the Lower Geyser Basin. This short, total 0.5-mile boardwalk loop strings together hot springs, geysers, mudpots, and fumaroles—everything Yellowstone’s hydrothermal system can throw at you—in one compact circuit. It’s easy, photogenic, and a no-brainer stop if you’re anywhere near Madison–Old Faithful.

What you’ll see

Start near Silex Spring, a brilliantly colored hot spring, then pass Red Spouter (often hissing like a steam vent) and Leather Pool. The namesake Fountain Paint Pot is the star mudpot—thicker and more blob-like later in the season, thinner and splashier in spring depending on moisture. A short spur heads toward Clepsydra Geyser, a crowd favorite for its near-continuous splashing from multiple vents. You’ll also pass smaller features (including Twig Geyser and others) that showcase just how varied this basin is.

Trail feel and flow

The entire route is on boardwalk. Expect one steep grade between Silex Spring and Fountain Paint Pot and some steps near Twig Geyser; if you avoid those sections, much of the loop remains friendly for wheels. Plan 15–30 minutes depending on how much you linger at the viewpoints.

Science corner

Hydrothermal features here sort themselves largely by how much water they have: water-rich hot springs and geysers on one end, water-limited mudpots and fumaroles on the other. This basin is also the broader area where heat-loving microbes critical to modern DNA techniques were first discovered—keep an eye on those rainbow microbial mats around the springs.

Best time to hike

Midday brings the tour-bus crunch and parking delays; aim for early morning or late afternoon for easier parking, softer light, and cooler temps. There’s little shade and it can be windy on the exposed flats, which adds drama to the steam—and risk to your hat.

Practicalities

There’s a dedicated parking area with restrooms at the trailhead. Stay on the boardwalk at all times—thermal ground is fragile and dangerous—and supervise kids closely. Expect sulfur smells, warm spray, and occasional muddy splatter near active vents; protect cameras and clothing accordingly. Pets aren’t allowed on boardwalks or in thermal areas (service animals excepted, must be leashed).

If you liked this

Artists’ Paintpots offers another short boardwalk with lively mudpots and a bit of uphill for basin views. If your timing lines up, pair this stop with Great Fountain Geyser along Firehole Lake Drive, one of the few geysers with prediction windows in summer.
