Most people drive right past Terrace Spring in Yellowstone National Park without realizing they’re skipping one of the park’s coolest hidden gems. 💦 This geothermal spring isn’t just hot water — it’s bubbling carbon dioxide escaping straight from Yellowstone’s active volcanic system. 🌋 The boardwalk trail is short, peaceful, and full of texture, color, and sound. It’s proof that even the quietest spots in Yellowstone have a wild story to tell. ✨ #TerraceSpring #YellowstoneNationalPark #HiddenG
