Lifjell has many mountains and valleys. If you walk from Jønnebu, there are many possibilities. If you go in the direction of Jøronnatten, but don't want to go all the way there, you can take one of the surrounding peaks. Nybufjellet is a fairly easy peak to climb, even though it is quite high at 1130 meters above sea level. The trails in this area are fabulous and very well marked.
