After Yellowstone, dip into southern Idaho to explore attractions, including two national park sites, you won’t find elsewhere.

1. Craters of the Moon National Monument & Preserve

Why go: Formed by eight major volcanic eruptions from 15,000 to 2,000 years ago, this otherworldly landscape in Arco, Idaho, makes you feel as though you landed on another planet.

Tip: If you only have 30 minutes, drive the seven-mile scenic loop. For a two-hour hike, park at the Spatter Cones parking lot and walk to Big Craters.

2. Shoshone Falls

Why go: Pronounced “Show shone” (the latter rhymes with phone), these falls on the edge of Twin Falls, Idaho, are higher than Niagara Falls, stretching 212 feet high, and sit along the Snake River. Take a dip in one of the hidden lakes in the canyon or picnic in the park.

Tip: Before you go, fuel up on breakfast or lunch at the Twin Falls Sandwich Co. in town, which has been named “best fish sandwich” by USA Today.

3. Perrine Bridge

Why go: This 486-foot-high bridge in Twin Falls spans the Snake River Canyon and is a popular spot for BASE jumpers to leap off and parachute down. Watch them from the pedestrian walkways.

Tip: Twin Falls Visitor Center is on the south side of the bridge. To the east, you’ll find interpretive signs and the dirt ramp Evel Knievel used when he tried to jump over the canyon in his steam-powered skycycle in September 1974. He crashed because his parachute malfunctioned but walked away with only a broken nose.

4. Lake Walcott State Park

Tip: After the reserve, head to the Rock City Grill, which has the area’s largest selection of beers and locally famous pizza.
