A bicycle trip through Yellowstone is a thrilling challenge, though there are routes available to cyclists of all skill levels. A week before the park opens to regular automobile traffic, bicyclists and hikers are welcome to explore under the power of their own two feet (April). The same opportunity is available to visitors in the fall. The 5-mile Yellowstone River route between the Reese Creek park boundary and Gardner is a great introduction to Yellowstone cycling, while Fountain Freight Road near Old Faithful is a classic 5.5-mile route through geyser country. Xanterra Parks rents bikes from their Old Faithful location, while Cycling Escapes offers a spectacular 6-day, 400-mile trip that rips along the Beartooth Scenic Byway.
