We have stayed at Hirtshals camping in the past a few times while on cycle tour in Denmark.
We were going to start our summer cycle tour by taking the late boat from Norway to Hirtshals and camping a night there.
Hirtshals camping was always a bit on the expensive side but now it will cost our family of four EUR 76-50 to stay for one night in late June. In our own tent!
I guess we take the early boat instead and then use the time to find a free camping spot.
