Idaho is a landlocked state in the Pacific Northwest and Mountain West regions of the United States, celebrated for its dramatic landscapes ranging from the Snake River Plain to the jagged Sawtooth Mountains. Home to Boise — a vibrant, fast-growing city — Idaho offers world-class whitewater rafting on the Salmon River, skiing at Sun Valley, and some of America's deepest river gorges. Potato farms, craft breweries, and a thriving farm-to-table dining scene round out a destination that rewards curious travelers willing to venture off the beaten path.

1
Craters of the Moon National Monument & Preserve
This is a vast field of basaltic lava flows, cinder cones, and spatter cones left by eruptions along the Great Rift that occurred as recently as 2,000 years ago. A seven-mile loop drive connects short walks to features like Inferno Cone and the Devils Orchard, and several lava tube caves are open for exploring. The landscape is stark and black rather than green, which is the whole point of coming.

2
Hells Canyon National Recreation Area
Hells Canyon is North America's deepest river gorge, cut by the Snake River between Idaho and Oregon, deeper than the Grand Canyon at its most dramatic points. Most visitors experience it either by jet boat or raft trip on the Snake, or by driving to overlooks on the Idaho side near Riggins, since there are no roads down into the canyon itself. It's remote country, and the scale is the main draw rather than any single built attraction.
-
3
Sawtooth National Recreation Area
The Sawtooth NRA protects a jagged range of granite peaks around Stanley and the Sawtooth Valley, with more than 40 peaks over 10,000 feet and hundreds of alpine lakes. It's a hub for backpacking, fishing, and horseback trips, with the town of Stanley serving as the main gateway. The scenery is the kind that draws people back for multi-day trips rather than a single stop.
-
4
Shoshone Falls
Known locally as the 'Niagara of the West,' Shoshone Falls drops over a horseshoe-shaped rim on the Snake River near Twin Falls, taller than Niagara Falls itself. Flow is heavily controlled by upstream irrigation dams, so the volume of water varies enormously by season. A park at the rim has viewing platforms close to the falls.
-
5
Sun Valley Resort
Opened in 1936, Sun Valley was the first destination ski resort built in the United States and still centers on Bald Mountain, a peak known for consistently groomed runs across a wide range of difficulty. In summer the area shifts to golf, hiking, and fly fishing, with the resort village retaining its old ski-town character. It's as much a historic property as an active ski area.
-
6
Lake Coeur d'Alene
This large lake in the Idaho panhandle is bordered by forested shoreline and the resort town of Coeur d'Alene, with the lake known for its clear water and mountain backdrop. City Beach in town gives free public swimming and lake access, while scenic cruises run from the nearby marina. It's a summer destination built around boating, swimming, and the lakefront resort scene.
-
7
Boise River Greenbelt
The Greenbelt is a paved multi-use path running roughly 25 miles along the Boise River through the city, linking parks, the Boise Whitewater Park, and neighborhoods on both banks. It's used constantly by runners, cyclists, and walkers rather than being a tourist attraction on its own, but it's the easiest way to see how the river shapes daily life in Boise. The Whitewater Park section adds kayakers and surfers riding a man-made wave feature.
-
8
Idaho State Capitol Building
Completed in 1920, Idaho's Capitol is built largely of Idaho sandstone and is notable for being geothermally heated, drawing on hot water from wells beneath Boise. The rotunda and legislative chambers are open to self-guided visits, and the building is one of the few state capitols built with a distinctly regional material and heating source. It sits at the head of Boise's downtown, making it an easy add-on to a walk through the city center.
-
9
City of Rocks National Reserve
A cluster of granite spires and domes near the Utah border, some rising 60 stories high, formed from rock that is among the oldest exposed on the continent. The reserve overlaps a segment of the California Trail, and wagon wheel ruts and pioneer signatures are still visible on some of the rock faces. It draws serious rock climbers for its granite routes as much as it does hikers and campers.
-
10
Bruneau Dunes State Park
Home to the tallest single-structure sand dune in North America, rising about 470 feet from the surrounding desert floor. The dunes formed in a natural bowl where wind patterns from two directions cause sand to accumulate rather than migrate away, which is why they've stayed largely in place for thousands of years. An observatory on-site takes advantage of the area's dark, unpolluted night skies.
