Park News - (3/25/20) I had not seen this elsewhere yet, but the park announced that they would be removing the Half Pipe coaster (Intamin) at the end of last season. They mentioned high maintenance costs and frequent periods of downtime as primary reasons for the ride’s removal.
2020 - Nothing new will be added in 2020. The park did mention that they were adding “new adventure lifts” to the Näsinneula observation tower.
2021 - (3/25/20) The park did mention that they planned to fill the gap left behind by the removal of Half Pipe in the near future. No timeline was mentioned, but by skipping out on adding anything in 2020, 2021 is likely when we will see a large new ride arrive.
