Fun-Plex

When it opened in the late 1970s, Fun-Plex enticed patrons with a single go-kart track. Since then, the park has accumulated a wealth of attractions, including a tilt-a-whirl, bumper boats, and Nebraska’s only roller coaster. Kiddie Land accommodates youngsters with a mini coaster and express train; Wet & Wild Water Park soaks visitors with a lazy river, kiddie pool, and two five-story water slides every summer from Memorial Day weekend to Labor Day weekend.

After toweling off, guests can take to the 18-hole miniature-golf course to putt past water hazards, sand traps, and gophers on vacation. Visitors craving indoor fun can try their hand at pinball or Pac-Man in the arcade or wander through a haunted house during the Halloween season. When it’s time to reenergize, patrons can choose from four restaurants with food ranging from carnival snacks to pizza and breadsticks.
