While the park is currently closed for redevelopment, it’s worth knowing about if you’re planning a return visit in the future.

Scandia was the go-to spot for mini golf, batting cages, and roller coasters like the Scandia Screamer, which—let’s be honest—felt like it was held together by duct tape and adrenaline. Families, teens, and date-night crowds loved the quirky Scandinavian theme, neon lights, and carnival food.

As of now, the property is undergoing a major transformation. The rides are gone (for now), but there’s talk of a reimagined entertainment center taking its place in the coming years.
