Craters of the Moon

Central Idaho

Lava fields, caves, and stark volcanic landscapes that feel more remote than they are.

Underrated things to do in Idaho

Hells Canyon

Idaho-Oregon border

North America's deepest river gorge, with rafting, jet boats, and big views.

Northern Idaho

Mining history, biking the Route of the Hiawatha, and mountain-town charm.

2026 planning notes

America250 makes 2026 a stronger-than-usual year for U.S. history trips, state capitols, museums, and Fourth of July events.

Mountain roads and high passes are seasonal.

Summer wildfire smoke can affect views.

Remote hot springs require leave-no-trace discipline.
