Idaho Falls — The Museum of Idaho, the Greenbelt Falls & the Birthplace of Atomic Power
Ninety minutes west over Teton Pass, the mountains fall away to the broad volcanic plain of the Snake River and the city of Idaho Falls, the largest city between Salt Lake and the Montana line and the cultural hub of eastern Idaho. Day one explores the city's civic heart: the Museum of Idaho with its ambitious traveling and regional exhibitions, and the celebrated Greenbelt, a riverside park where the Snake tumbles over a broad man-made falls beneath the gleaming Idaho Falls Temple. Day two drives out onto the stark lava plain to EBR-1, the retired reactor where atomic energy first produced usable electricity in 1951 — now a National Historic Landmark you can walk through — before returning along the Snake to Jackson. It is a two-day arc from pioneer settlement to the frontier of the atomic age.

Museum of Idaho
★ 4.6The premier museum of eastern Idaho, the Museum of Idaho occupies the historic 1916 Carnegie library building expanded by a modern wing, and it is best known for hosting large national touring exhibitions — everything from Titanic artifacts to full-scale dinosaur and Body Worlds shows have stopped here. Its permanent 'Way Out West' gallery traces the region's story from the Shoshone-Bannock peoples and the fur trade through Oregon Trail migration, Mormon settlement, and the coming of the railroad that gave Idaho Falls (originally 'Eagle Rock') its start. Interactive exhibits and a strong natural-history component make it engaging for all ages. Allow a couple of hours, and check which touring show is on before you go.

Jaker's Bar and Grill, Idaho Falls
A well-regarded Idaho Falls institution serving steaks, prime rib, seafood, and a generous salad bar in a comfortable setting near the river. It is a reliable midday choice with broad appeal after a morning at the museum, and portions are ample. An easy place to regroup before an afternoon walking the Greenbelt.

Afternoon
Idaho Falls Greenbelt & the Falls
★ 4.8The city takes its name from the broad, curving waterfall on the Snake River at its center — a low, wide cascade created when a diversion dam was built in the early twentieth century, stretching some 1,500 feet bank to bank and thundering white below the downtown. A five-mile paved Greenbelt loops both banks, threading past gardens, sculptures, and river overlooks, and it is the finest urban walk in eastern Idaho. Above the west bank rises the white spire of the Idaho Falls Idaho Temple, dedicated in 1945 and mirrored dramatically in the water; its visitor center and grounds are open to the public. Walk the loop in late afternoon when the light gilds the falls and the temple.

Snake Bite Restaurant, Idaho Falls (dinner)
A cozy, well-loved bistro near the river serving inventive American plates, generous salads, and a good beer and wine list — a step up from the town's steakhouse standards and a pleasant place to end the first day. The atmosphere is warm and casual, popular enough that a reservation helps on weekends. It sits within easy reach of the Greenbelt and downtown lodging.

Residence Inn / Hilton Garden Inn Idaho Falls
Idaho Falls has the fullest range of lodging on this side of the Tetons. The riverside hotels near the Greenbelt — the Residence Inn and Hilton Garden Inn among them — put you within walking distance of the falls and downtown dining, an ideal base for the itinerary. Budget and mid-range chains cluster along Lindsay Boulevard and near the interstate for those wanting a lower rate. Book ahead in summer, when the city fills with travelers heading to Yellowstone and the parks.

EBR-1 Atomic Museum
★ 4.8Out on the lava plain west of Idaho Falls stands Experimental Breeder Reactor No. 1, where on December 20, 1951, electricity was first generated from atomic energy — enough to light four bulbs, and the next day the whole building. A National Historic Landmark, EBR-1 is preserved as a walk-through museum where visitors can see the reactor core face, the control room with its original instruments, the shielded remote-handling arms used to manipulate radioactive material, and two massive prototype aircraft-nuclear-propulsion engines parked outside. Self-guided and guided tours run in the summer season and admission is free. It is a genuinely extraordinary place — the birthplace of civilian nuclear power, set amid the vast, empty desert of the Idaho National Laboratory. Confirm seasonal hours before making the drive.

The Celt Pub & Grille, Idaho Falls (lunch)
Back in town, this relaxed Irish-style pub near the Greenbelt serves burgers, fish and chips, sandwiches, and hearty pub plates — an easy, satisfying lunch before the last stretch along the Snake. The atmosphere is casual and the portions are generous, a comfortable place to break the day between the atomic museum and the river walk. It sits close to the downtown riverfront for a final stroll afterward.

Afternoon
Snake River Landing & Greenbelt South Loop
★ 4.5Before turning east for the mountains, walk the southern half of the Greenbelt around Snake River Landing, a newer riverside district of promenades, plazas, and public art where the Snake runs wide and calm above the falls. Interpretive markers along the water recall the river's role in the region — from Shoshone fishing grounds to the pioneer fords and the diversion dams that powered the city's growth. It is a pleasant, low-key last stop that keeps you by the river that has shaped everything on this trip, and lets afternoon light settle over the water before the drive back over the pass.
