The Granite Highline is a 29.2-mile out-and-back trail located in Wyoming.

The Wyoming location places it in a region known for expansive wilderness views and varied terrain ranging from alpine meadows to rocky ridges. Proper preparation is essential for this lengthy route, including adequate water supplies, navigation tools, and weather-appropriate gear. Hikers should verify current trail conditions and any seasonal closures before planning a visit, as Wyoming's backcountry can present variable conditions depending on the time of year.
