Fountain Paint Pot Trail

This is Yellowstone's geology sampler platter — a short boardwalk loop through the Lower Geyser Basin that packs all four types of hydrothermal features into roughly half a mile. You'll start with brilliant blue hot springs so clear you can see straight to the bottom, then pass hissing fumaroles venting sulfur-scented steam, bubbling mudpots that sound like a pot of oatmeal left on the stove too long, and finally a handful of geysers that may or may not perform while you're there. The boardwalk is flat and well-maintained, winding through a stark, otherworldly landscape where the ground itself is alive. The namesake paint pots — thick, pasty mud in shades of pink and gray — are the highlight, especially in late summer when the mud thickens and the plops get dramatic. Perfect for families, first-time Yellowstone visitors, and anyone who wants a concentrated dose of thermal weirdness without committing to a longer hike.
