Salmon to Jackpot: Idaho's Scenic, Lonely Highway

At mile 122.4 on US-93, the Salmon River's chirping currents give way to the high-desert silence of the Jarbidge Valley. This highway, a vital north-south artery, was originally a stagecoach and Pony Express route.

Rest Areas and Fatigue

Plan breaks at the rest area near Challis and the public restroom in the small town of Clayton. To combat fatigue, set a timer to pull over every hour even if you don't feel tired.

Weather and Route Aesthetics

The route experiences four distinct seasons: hot, dry summers with occasional thunderstorms; mild autumns; cold, snowy winters with occasional closures; and windy springs. Spring brings wildflowers, while fall offers golden aspen groves.

Family and Pet-Friendly Framework

This route is suitable for families with older children who can endure long stretches. Pets are allowed at rest areas and in most outdoor sites. The only pet-friendly lodging is in Jackpot, where some casinos allow pets, but call ahead.

• Salmon has a riverside park for a quick picnic.
• In Challis, the nearby hot springs are a family favorite.

Hidden Off-Route Spots

Turn off at mile 16 onto Forest Road 330 toward the Birch Creek Petrified Forest, a 60-million-year-old fossil grove. Later, detour 20 miles from Challis to the Bayhorse ghost town, once a booming silver mining camp.

Road Quality and Safety

US-93 is a two-lane road with wide shoulders and occasional passing lanes. Asphalt is in good condition, but be prepared for deer and cattle crossings, especially at dawn and dusk. The road is well-maintained year-round, with snowplows servicing it during winter.

Fuel and Route Economics

Fuel is available in Salmon ID at the start, again in Challis (50 miles south), and finally in Jackpot NV. At current prices, you'll spend approximately $15–$20 on gas for this segment. Avoid skipping Challis; the 60-mile stretch after it is desolate.

• Best gas prices usually found in Salmon due to Idaho's lower fuel taxes.
• Jackpot has several casinos with cheap gas to lure Nevada-bound travelers.

Geology and Scenery

As you leave Salmon, the route follows the Salmon River through the Salmon-Challis National Forest, offering granite cliffs and pine forests. After Challis, the landscape opens into sagebrush steppe, marked by volcanic rock formations from the Craters of the Moon volcanic field.

Culinary Infrastructure

Dining options are sparse. In Salmon, try the local bakery for pastries. Challis has a few diners serving classic American fare. Jackpot is known for its casino buffets, offering 24/7 prime rib specials, a stark contrast to the rural road.

• No formal restaurants for 90 miles between Challis and Jackpot—pack snacks.
• Local convenience stores in small towns offer basic groceries and drinks.

UNESCO and Cultural Sites

Although no UNESCO World Heritage Sites lie directly on the route, the nearby Craters of the Moon National Monument is a designated National Natural Landmark, featuring lava tubes and cinder cones. The region is also rich in Native American history, with the Shoshone people having inhabited these lands for thousands of years.
