Common sense
really, if a gate is open then leave it open as you may cut off livestock from a watersource, if it's closed close it. You'll find it much more open than most parts of the uk particularly the high country down south,
Like the highlands the weather can turn in an instant in places, so pack accordingly. Seems like every other week you read about some gormless tourist overnighting after going out equipped for a picnic in shorts and jandals.
if you are doing any serious solo stuff i cannot recommend renting an epirb enough.
If you are into hunting then try and tag along on a pig hunt.
erm what else don't be tempted to burn any of the giant pine cones - as you can flog these to tourists for a tidy sum allegedly
Check out the
doc website they are a good organisation.
