Salmon to Coos Bay: Epic Road Trip Guide

Starting in Salmon, Idaho, the route to Coos Bay, Oregon covers roughly 700 miles and crosses the Continental Divide at 7,037 feet via Lost Trail Pass (US-93). This pass closes seasonally due to snow, so check conditions in winter.

The drive typically takes 12–14 hours without stops. The route includes dramatic elevation changes, from high deserts to coastal rainforests, making it a scenic but demanding journey.

Key highways: US-93, I-84, I-5, OR-38, and OR-101. Fuel stops are sparse in eastern Oregon, so plan accordingly.

Weather ranges from −20°F in Idaho winters to mild 50°F on the Oregon coast. Pack layers and emergency gear. Summer thunderstorms can bring hail on high passes.

Fatigue zones: recommend taking breaks every 2 hours. Rest areas are abundant on I-84, but scarce on OR-38.

Family-friendly stops: the Oregon Trail Interpretive Center in Baker City (kid-focused exhibits), and the High Desert Museum in Bend (detour off I-84). Pets are welcome at most rest stops, but check hotel policies.

Hidden gems: the Malheur National Wildlife Refuge near Burns, home to 300+ bird species. For off-route adventure, detour to Crater Lake (adds 2 hours) on OR-62.

Fuel stations cluster around urban centers; between them, stretches of 100+ miles have none. Carry extra fuel or plan stops at Burns, Ontario, and Eugene.

• Fuel costs estimate $0.15/mile; total ~$105.
• Road quality varies: US-93 is well-maintained but winding; I-84 is smooth interstate; OR-38 is narrow with limited shoulders.
• No tolls on this route.
