Circles, squares and diamonds: Understanding trail designations
These symbols represent a ski resort trail designation system that categorizes ski and snowboard slopes by difficulty. Resorts throughout North America (and much of the world) use green circles, blue squares and black diamonds to indicate difficulty. Nordic trail systems also often use these symbols. Each resort ranks it’s own trails based on the relative difficulty of their specific area.
