The parks are awesome and getting better every year. This year we had a jib then 4 jumps (including the 60 footer at the end in the vid) plus probably 7 jibs beside and they also had a canon rail and up box at one point big enough to flip off. They also have another 2 smaller parks with jumps and jibs. Its everything you need for park and there is also Thredbo (half an hour down the road) with a similar sometimes even better set up than that and an air bag but the mountains themselves arnt that great.
