Two other things to note. This year it has been extremely dry in the forest. There is less fresh flowing water and I have been struggling to refill in places. Bring extra water for the forest part south of Lillehammer.

A Bivy is great but there are many mosquitoes this time of year. Ensure you can cover your face. They will be flying around you at night in the forests.
