There is a risk where ever you go. But in the highlands the risk is higher, in my opinion. People get lost and die in the highlands every year. Not knowing the ground is the first issue. Peat bogs, some big enough to swallow a truck, break a leg and your in trouble, sprain your ankle and you are in trouble. In the autumn and winter you can get all 4 seasons in an hour. Its not unusual for people to get lost, and every year there are fatalities.
Many stalkers from the south, have no idea what to expect when stalking the highlands. The biggest area I have managed was over 40,000 acres with 3 Munroe's.
I used to take people off this site for Level 2, and or the highland experience on a lease I had in the highlands. But after having one guy get lost within an hour of being there, after being told, to stay where he was, and we would be back in 10 minutes, and another slicing his finger off with paracord, 4 miles out in the hills, I decided to pack it in.
Remember the BASC scheme on Arron, some years back? Dropped a single client off, on his own. They found his body 3 days later. I admit there was little anyone could do to help him, but if he had been with another stalker it would have saved a lot of time, money and more importantly grief for the family.
Any estate who lets a complete novice out on their own in the highlands in asking for trouble, in my opinion.
