"Hiking trips with pack animals for kids/children." I've never come across this expression before so I had to do some research. From that I gathered that a 'kløv' is the equivalent of saddlebags, and in the context used in Norwegian a 'kløvtur' is then a hiking trip with any animal capable of carrying them. That means horses, dogs and even lamas (!). You can use 'packhorse' instead of pack animal if you know for sure they use horses.
