The short answer
Mammoth Hot Springs is the closest major Yellowstone sight to Bozeman — about 85 miles (1 hour 40 minutes) via Paradise Valley and Gardiner — and it’s reachable by car all year. Boardwalks climb stepped travertine terraces, and elk often graze on the lawns of historic Fort Yellowstone.
