2018 - Samba Ballon / Cannonbowl - (8/14/17) Waldameer Park has confirmed that for 2018 the park will install a Samba Balloon ride (Zamperla) near Kiddieland and the Cannonbowl tube slide (ProSlide) in the waterpark. The article also confirms that the park's late opening Battle of Lake Erie water fortress attraction did open to guests sometime in July.
(8/29/16) A reader visiting Waldameer Park came across some banners posted on the wall at the new construction area. Unfortunately the images are tiny, but we can see the newly announced splash fortress expansion on one of them, listed as "2nd Expansion" which was placed by the wave pool area, but another banner listed as "3rd Expansion" shows off the long awaited Bowl slide and was placed along the right side of the food service area. Nothing was said about a timeline, but I'm guessing the Bowl slide may now be in the pipeline for 2018.
2019 - Zamperla Discovery Revolution - Confirmed - (3/13/18) Waldameer Park has announced a new Zamperla Discovery Revolution ride is coming to the park for the 2019 season, to be called Chaos. The announcement was made earlier this month during an ACE event where they said that the new ride would be located near the park's train station, in an area currently used for picnics. This is also said to be the first ride at Waldameer that will flip riders upside-down.
