Although by law they can require you to leave, they generally are more than willing to share the shelter. Please keep this in mind if you camp in a cattleman's hut. Mountain cattlemen are allowed by law to bring their working dogs in the Alpine National Park. If you are using a cattleman's hut, please replace the firewood. Please also do not remove any tools from the hut, or damage the log book.
Log books are often valuable if it is necessary to search from somebody lost in the vicinity.
Cattle are taken up to the high country in December and are brought down in April. Enjoy the spectacle but be careful on alpine roads and tracks around these times. Cattle do not have a very good road sense. Amazingly, some people try to muster cattle on the high plains. This is a really dangerous thing to do and can result in cattle being driven off their designated area.
