Join NextDoor, and ask your neighbors what's available in your area.
Otherwise I would say "strap a soapy carwash sponge to his chest, and let him crawl around your kitchen and bathroom floors."

Ceramics or spoon-bending!

Hi

something far away from other people at this moment!

Check out the Bay Model Visitor Center in Sausalito.  It's an indoor scale model of the Bay the size of 2 football fields with a wave maker that mimicks the tidal patterns of the Bay.  Free, and your toddler can tire himself/herself out running in all that space.

2 is a tough age...honestly, I would stick to parks with swings and slides. Try researching ones that would be worth the drive - maybe it had a nice view or there are lots of other kids to socialize with (and sometimes for mom, too. But most of the time I couldn't stand other idiot parents).

The idea is to wear the kid out. Wake him up early and don't let his ass nap until you say. Then wake his ass up if he goes over two hours.

You can also always try the parks are Recs classes. Not free but very inexpensive and there are plenty of mommy and me swim classes and toddler gyms and shit like that.

Also, the tiny crabs cove in alameda is free. It has some fish to watch, etc. It's been smelly af lately, just warning you.

"Tiny Crabs Cove" is a dangerous, dangerous place
