Yellowstone South

About This Tour

You're driving atop a 30x40 mile supervolcano—and it's still active. The Southern Loop showcases what happens when that volcanic heat meets groundwater: over 10,000 thermal features including the world's largest concentration of geysers, rainbow-colored hot springs, and bubbling mud pots.

This GPS-triggered audio tour covers the southern roads from Old Faithful to Yellowstone Lake, through the geyser basins and past iconic landmarks. You'll understand not just what you're seeing, but the extraordinary forces that created it.
