Getting there and around
Getting there
Idaho is accessed primarily through Boise Airport (BOI), offering direct flights from major western cities and connecting flights nationwide. Regional airports include Idaho Falls (IDA), Spokane International (GEG) serving northern Idaho, and smaller airports in Sun Valley, Lewiston, and Pocatello. Interstate highways I-84 (east-west through Boise), I-90 (northern corridor), and I-15 (eastern edge) provide road access. US highways connect to Yellowstone and Grand Teton National Parks. Amtrak’s Empire Builder stops in Sandpoint serving the northern panhandle. Greyhound and regional bus lines connect major cities. Mountain passes can close in winter – check conditions on 511.idaho.gov.
Getting around
Idaho requires a car for most travel as public transportation is minimal. Boise’s Valley Regional Transit offers basic bus service with limited evening and weekend hours. Coeur d’Alene has CityLink buses, while other cities have minimal or no public transit. Rental cars are essential for exploring scenic byways, national forests, and accessing ski resorts. Uber and Lyft operate in Boise, Coeur d’Alene, and college towns but are unavailable in rural areas. Downtown Boise, McCall, and Sun Valley/Ketchum are walkable. Winter driving requires experience with snow and ice – carry chains November through March. Gas stations can be 50+ miles apart on rural routes. Many attractions are accessed via Forest Service roads requiring high-clearance vehicles.
Top experiences in Idaho

A world-class ski destination. Bald Mountain is legendary. In summer, it is great for hiking and ice shows. The town of Ketchum is charming and upscale.

A weird, volcanic landscape. Miles of black lava flows and cinder cones. Astronauts trained here. It feels like another planet.

A stunning mountain lake. Popular for boating, fishing, and eagle watching (in winter). The floating green at the golf course is iconic.

Culture, customs and safety
Cultural heritage
Idaho’s cultural and historical heritage is shaped by its Indigenous roots, frontier legacy, and striking natural landscapes. The state is home to several Native American tribes, including the Nez Perce, whose ancient traditions and oral histories remain central to the region’s identity; the Nez Perce National Historical Park preserves sacred sites and artifacts. Idaho’s settlement history is marked by pioneer trails, mining booms, and railroad expansion, which left a distinctive imprint on its architecture and ghost towns. Agricultural traditions—especially potato farming—continue to influence local identity and economy. While Idaho has no UNESCO World Heritage Sites, its Craters of the Moon National Monument evokes global geological interest as a rare basaltic landscape shaped by ancient volcanic forces.
Local customs & etiquette
Idaho culture values self-reliance, outdoor recreation, and conservative values. The state motto “Esto Perpetua” (Let it be perpetual) reflects pride in natural beauty and lifestyle. Outdoor activities dominate social life – hiking, fishing, hunting, skiing, and camping are conversation starters. Gun ownership is common and hunting season is culturally significant. Potatoes are the state’s identity though locals tire of jokes. Craft beer culture thrives in Boise. Ranch and Western wear is common outside cities. LDS (Mormon) influence is strong, particularly in eastern Idaho. Tipping standard is 15-18%. Business culture is casual except in Boise’s downtown. Respect private property rights – always ask permission before accessing land. Environmental stewardship matters despite political differences. Small-town values emphasize knowing neighbors and community support.
