Oakland Aviation Museum

*Sulphur Creek Nature Center (Hayward Area Recreation & Parks) has lovely woodsy indoor/outdoor spaces, animal exhibits & meet-n-greets, and they offer birthday party packages. This is a native wildlife rehab facility and a learning center that has some very dedicated and knowledgeable naturalists.

*Lawrence Hall of Science, 'Animal Discovery' parties in their downstairs lab area.

*EBRPD Tilden Nature Area's Environmental Education Center's or the Little Farm. This one may be outdoors-only, chk for indoor options. Bundle the kids up and take them around to feed the cows, pigs, chickens, geese and goats, then a walk along the long wooden trail.

EBRPD Crab Cove Visitor's Center, Alameda Island. Search for East Bay Parks Online 'nature party'. This is a lovely indoor area with interactive estuary / bay shore exhibits. Could also do a nature walk along the water.

Finally, just have to give a shout out to the Oakland Aviation Museum near the Oakland Airport. Not very toddler-friendly for climbing/touching, but lots of vintage planes to look at, some interesting flight exhibits, and a large space for a party - both indoors and out.  Tables in the hangar might be a way for you to bring your own airplane-focused games, crafts, and party favors to keep the party-goers content and busy? They have a nice aerospace gift shop too.

Hi - we had birthday parties at the Oakland Aviation Museum - twice! It's a wonderful, large space with a lot of exhibits for guests to see.  They opened up the Solent Flying Boat for guests to visit.  This was several years ago.  If I remember correctly all they asked was a $100 donation and for us to set up and take down.  The staff was very kind and it was a really good experience.
