Pros:
The north course is very good both in variaty of holes and maintenance. Some holes are more open but most of them are tight ones in the woods. A few cool tees overlooking the area. No particular cons regarding the north course, play it if you´re in the area!
Cons:
The south course however is much worse, it feels like they just put up a teepad and a basket and did nothing else. Some holes goes through the side of a slope with lots of rocks on it. On some holes we had problems even walking towards the basket because of fallen trees and big rocks.
Other Thoughts:
Visit the park, but only play the south course if you really want to try it. I wont be playing the south course next time im going out there. The north course is on the other hand very good and should be played in a heartbeat if you´re around Bromma/Ekerö, Stockholm.
