Tips for a Memorable Scenic Drive
Timing – Start early to capture soft morning light for photography and to avoid midday heat in summer. Midweek drives (Tuesday-Thursday) tend to be less crowded.
Gear – Pack a camera, binoculars (for spotting elk, eagles, and wild horses), and layered clothing for unpredictable weather shifts. A cooler with snacks and water is essential for remote stretches.
Safety – Cell service is limited in some areas—download offline maps from visitidaho.org. Be cautious of wildlife crossings (especially on Highway 55 and the Owyhee Byway) and yield to cyclists on the Greenbelt.
Fuel & Services – Fill up in Eagle or Boise; Cascade, Idaho City, and Grand View have limited gas stations. Bring cash for small-town stops like Idaho City or Silver City.
Weather – As of March 8, 2025, spring is arriving with mild temps (50-60°F), but check forecasts for rain or late snow before heading out.
Food Stops – Pair your drive with a local eatery—grab a meal at a pub in Cascade, try The Basque Market in Boise, or pack a picnic to enjoy the remote beauty of the Owyhee wilderness.
