The Access Code says:
Be aware of where recreational use is likely, such as along paths, popular routes and ridge lines. Tell people about where stalking is taking place, for example by using the Heading for the Scottish Hills service or using signs and information boards (in accordance with this Code), to give on-the-day information on stalking and alternative routes.
Heading for the Scottish Hills provides a simple way for land managers to tell people where deer stalking is taking place. The service can help to reduce disturbance, as well as promoting responsible behaviour and understanding of deer management.
