• Fuel stops: every 30-50 miles along interstates; remote sections on US-95 in Idaho require planning (e.g., between New Meadows and Grangeville, 70 miles without services).
• Best fuel prices: often in Pocatello, ID and Boise, ID; cheaper than SLC or Spokane.
• EV charging: Tesla Superchargers in SLC, Tremonton, Pocatello, Burley, Twin Falls, Boise, Grangeville, Coeur d'Alene, Spokane. CCS/CHAdeMO available at many same locations.
• Road conditions: check 511 for each state (UT, ID, WA). Winter requires chains or snow tires in mountain passes (e.g., mountain pass near Snowville).

Accommodations: Motels and hotels are plentiful in cities (Pocatello, Twin Falls, Boise, Coeur d'Alene). In smaller towns like Arco or Salmon, book ahead. Camping: numerous BLM lands and national forests (e.g., Sawtooth NF, Payette NF).

The route showcases dramatic transitions: from the Great Salt Lake's desert basin to the Snake River's volcanic plains, then the forested Selkirk Mountains. Craters of the Moon National Monument (near Arco, ID) offers surreal lava fields and cinder cones, a must-see detour.

Local commerce: farm stands selling huckleberries (Idaho state fruit) in summer; wineries in the Snake River Valley AVA (e.g., Koenig Vineyards, Sawtooth Winery). In Spokane, explore the Kendall Yards neighborhood for local artisan shops.

Road quality: interstates well maintained; US-95 from Grangeville to Lewiston has winding sections with limited shoulders. Winter driving: carry chains, blankets, and food; avoid night driving in remote stretches.

• Family-friendly stops: Yellowstone Bear World (Rexburg, ID); the Idaho Potato Museum (Blackfoot, ID) – learn about the state’s iconic crop; Silverwood Theme Park (Athol, ID) – thrill rides and water park.
