49’er Fun Park began life in the late 1980s as a mom‑and‑pop miniature‑golf course tucked into Grass Valley’s pine‑lined foothills. By the early ’90s, batting cages, bumper boats, and a Namco‑leaning arcade expanded the footprint, turning the spot into Nevada County’s de facto birthday‑party HQ. TripAdvisor reviews from the 2010s still rave about redemption tickets and “old‑school” joystick classics.
Even county resource guides list the park as an all‑ages recreation staple, underscoring its longevity despite Northern California’s fickle tourist economy. While the dedicated arcade building closed during the 2020 pandemic slowdown, the operators kept a handful of cabinets in the snack bar. The facility likely closed in 2023, when their website went offline.
