Departing Medora, Theodore Roosevelt National Park's South Unit is a must: sculpted buttes, wild bison, and prairie dog towns. The 36-mile scenic loop (US-85/ND-94) takes 1-2 hours. Continue west to Makoshika State Park (Glendive, MT) for eerie dinosaur fossils and steep canyons—a hidden off-route spot. For something truly unique, visit the Painted Canyon Overlook (exit 32, I-94), a kaleidoscope of color. Between Billings and Bozeman, detour south on MT-78 to Red Lodge for the Beartooth Highway (US-212); it's seasonal (late May-Oct). The drive along I-90 then threads through the Gallatin Valley, with views of the Bridger Range. Approaching Hamilton, the Bitterroot Mountains rise to the west; stop at the Lee Metcalf National Wildlife Refuge (exit 85) for birdwatching.

Key highways include I-94 from Medora (ND exit 27) west to Billings, MT (210 miles), then I-90 west to Hamilton (MT exit 76). An alternative scenic route takes US-12 from Miles City to Butte, adding 1 hour but offering vast prairie views. Gas stations are sparse on certain stretches, particularly between Glendive, MT and Miles City (60+ miles). Fuel up in Medora, exit 24, or at the trucks stop in Beach, ND (20 miles west).

Wildlife crossings: dawn/dusk between Glendive and Billings (deer, elk). Use high beams on open stretches.
