Select participants and date
The engine hums as the road unwinds and steam rises like a live map ahead—bubbling pools, columnar cliffs, a lone bison outlined against morning mist. You’re on the Grand Loop, a 140-mile ribbon of asphalt that stitches Yellowstone’s geothermal theater, high lake shores and wide, predator-rich valleys into a single day’s drive. The audio guide cues up automatically, a calm narrator filling the pauses between sightlines with geology, history and practical pointers so you can pull over when the park demands attention.

Adventure Tips
Download the app and tour in advance
Cell service is unreliable—download the Drives & Detours app and the Yellowstone tour (enter access code) before you hit the entrance station.
Start at first light
Begin early to avoid crowds, see wildlife in low light and secure parking at popular viewpoints like Old Faithful and Grand Canyon of the Yellowstone.
Plan fuel and restrooms
The Grand Loop is long—top off gas and map restroom stops before you leave towns like Gardiner or West Yellowstone to avoid long gaps between services.
Respect wildlife and boardwalks
Stay in your vehicle for bison jams and keep the posted distance from thermal features—boardwalks protect both you and fragile ground.
