Nummenmäki DiscGolfPark is a 21-hole, very challenging forest course in Nummenmäki, Hyvinkää. The stage of the 2017 Finnish Championships. Most of the fairways are narrow-side gutters bordered by a thick forest. Getting lost on the fairway is easily followed by extra throws. However, the throwing lines vary widely and almost everyone seeks a slightly different line. The best place to park your car is on the other side of the Aviation Road, at the intersection of the Aviation Road and the Airports.
