There are so many reasons parents like to take their kids to enclosed parks. Once you find one with a gate, you can end up playing it out since it’s the only place you’re pretty sure you won’t lose a kid.
This document-in-progress is as much information as I have yet compiled about enclosed Bay Area parks and playgrounds. I will keep updating it as we visit parks and friends send in tips. Please leave any tips in the comments here, or use the comment feature to add information to the document. I will update it as soon as I can. I’m so grateful for the collaboration and feedback!
