Idaho Falls sits along the Snake River in eastern Idaho and is named for the beautiful waterfalls right in the middle of the city. It is a gateway to Yellowstone National Park.
You can walk the scenic River Walk beside the falls, explore the Museum of Idaho, and see fish and reptiles at the fun Tautphaus Park Zoo.
The Idaho Falls River Walk is a lovely paved path along the roaring waterfalls, with grassy spots for picnics and views of the white temple.
Idaho Falls is a starting point for family trips to Yellowstone and Grand Teton, where you can see geysers, bison, and towering mountains.
