Hynkeberget is a small crag with four sectors. Ydinjengi, Pitti and The Wall are the ones worth visiting. Ydinjengi is in good condition due to the overhanging nature of the cliff face, but the other sectors are quite mossy and require a lot of brushing before being climbable. Be prepared, if those have routes you want to climb.
The rock quality is pretty sharp, but the climbing is worth it. The approach is not short, remember to read the part on access. Most of the sectors are quite shaded due to the surrounding forest. Be sure to take multiple pads, especially if you climb at Ydinjengi or Pitti.
