Beyond the ropes · Through gates
Shiga Kogen marks its side-country exits with a warning sign that tells you that you are leaving the ski area. The resort-wide side-country map shows where riding outside the runs is tolerated, and everything outside that mapped area is closed.
- Leave the runs only at an exit marked with the side-country warning sign
- Never enter the closed areas shown on the side-country map or ride past a 'no entry' sign
- Carry proper safety equipment and know how to use it before going through an exit
- If patrol has to search for or rescue you outside the ski area, the resort bills you for the full cost
- Read the Japan Avalanche Network bulletin before you go out
