Adventureland will celebrate its 50th anniversary in 2024 and the popular Underground roller coaster will reopen with a refurbished train and track after sitting idle for 2023.

Tour this old mine at Adventureland so you can try to solve the mystery of Bad Bob. Underground is a unique combination dark ride and enclosed wooden coaster. Multiple lift hills keep the train moving along the 911-foot-long track that features scenes, lighting, and special effects.
