Crib Goch is described as a "knife-edged" arête in the Snowdonia National Park in Gwynedd, Wales. The name means "red ridge" in Welsh.
The highest point on the arête is 923 metres above sea level. All routes which tackle Crib Goch are considered mountaineering routes in winter or scrambles in summer—meaning that they must cross "graded territory" as defined in Steve Ashton's Scrambles in Snowdonia. The easiest of these lines is given a scrambling grade of Grade 1.
