In reply to Louis Kennedy:
Some advice coming from Canada where wolves and bears are a fact of life. Bear bells are ridiculous. Nothing screams 'rookie' than a bear bell. If you're concerned about startling a bear (e.g.: in dense undergrowth) then use a loud authoritative call with your own voice - think Attenborough watching chimps scare off lions. But by in large bears are a non issue - I can't speak for Norway but if they've survived this long in over-populated Europe I suspect they know to keep well out of the way of humans. The main thing is to keep your food secured and avoid stinky foods like fish and meats. Bears have no interest in oats or dehydrated beans, rice etc...
As for wolves - it was long the lore that there was no real recorded attack by a wolf on a person other than the odd tale of a old, sick wolf.. bla bla bla. But gradually in high use areas wolves are becoming more aggressive in trying to steal food. Same advice goes - don't bring fish or meat into wolf habitat. But unless there is a posted warning it is highly unlikely a wolf is going to choose you to rob of your goodies.
As you'd expect, if you have an encounter with any wildlife read their body language. Often what on the surface looks threatening is in fact defensive. Yes you may have to be prepared to fight for your life but that's chance in a gazillion. More likely you need to adopt an assertive posture and calmly move away.
Have a great trip. When you;re ready come to British Columbia where you can really see these animals in the wild.
