Jolly Roger Land

If you’ve got kids under 12 and live anywhere near Union City, this place is worth knowing about. It’s an indoor spot, which means it actually works on those grey Bay Area days when you need somewhere to burn off energy fast. There’s a solid mix of climbing structures and swings, plus a bike track that the older kids genuinely get into. Toddlers have their own dedicated zone, so you’re not constantly pulling a two-year-old out from under a climbing wall meant for bigger kids. Restrooms on-site, clean facilities — parents around here will tell you that alone makes it worth the trip.
