5 stars for the memories and nostalgia, 4 stars for what it actually is, an above average theme park. For me, it was always easy to spend an entire day here. There is a fee for entering and then fees for rides, you can get the wristband that gives you unlimited rides apart from a few attractions. For a whole family though this gets a bit pricey. There are a lot of concerts in the summer. I believe the park is only open in the summer months.
This is an old style theme park, so don't expect all the latest and craziest state of the art rides. But it has a good mix of family friendly rides with some adrenaline rush rides too. And some that are good for the kids. Some rides have been there since forever, but they do put in new ones once in a while, the variety is pretty good. The viking ship, magic carpet, haunted house (live ghost actors), bumper cars, ghost train, flying swings, lady bug, fun house and free fall tower is what comes to mind. The rollercoaster is a bit tame and not among the top 5 in Europe.
In the 90s (not anymore) there used to be a theme park attraction inside Grona Lund with separate entrance fee, where people (slightly intoxicated and obnoxious men) would throw rubber balls on girls sitting in bikinis on a ledge by a pool and if the girls were hit they would fall into the water. This was an actual thing, if you can believe that! I don't see an activity like that going down well in this day and age. Just, for the record I never took part in this myself, I would have been 12 years old and too shy to talk to girls, let alone throw balls at them.
The general atmosphere and park grounds are pleasant, some folks enjoy just walking around, playing some carnival games and getting snacks.
