Things to do in Rancho Cucamonga

Here’s the honest version. Rancho Cucamonga’s best days are built from a shortlist of genuinely good pieces: a waterfall hike that earns its 7am parking lot, minor-league baseball with mountains over the outfield wall, the hand-built house of America’s greatest woodworker, a 1915 gas station you can walk into, and an open-air downtown that does the work a historic core would in an older city.

Two things make 2026 different. Route 66 — which runs straight through town as Foothill Boulevard — turns one hundred, with a year of centennial events. And the city’s wine story, the valley that once grew more grapes than Napa and Sonoma combined, is finally getting told properly. Both get their own guides here.

Everything below is verified and current. The attractions other sites still list — the demolished speedway, the closed winery, the mini-golf that’s gone — aren’t here, because sending you to a locked gate is how a city guide loses the only thing that makes it useful.
