What's Open on Christmas?

When I was growing up, it was our family tradition to go to the movies on Christmas. Luckily, most movie theaters are open on Christmas. They're not the only game in town, though.

Outside Stuff that Doesn't Close That's Fun at Christmastime

Little Farm is open on both Christmas Day and Christmas Eve because the animals still gotta eat!
A big list of outdoor destinations for families, most of which are accessible on holidays and totally toddler-friendly.
Plan your day around being at a great holiday light show when it gets dark. We like Christmas Tree Lane in Alameda and the smaller Mountain View cemetery in Piedmont.
Head toward the water. Try Oakland's Shoreline Park where you can see the big container ships. Or fly kites in the Berkeley Marina if it's not raining.
Explore the caves at Rock City. A windy drive to a fun place to rock scramble and take pictures.
Bring your wheels to a flat elementary school playground or the Ohlone Parkway in North Berkeley (more places to learn to ride a bike >).
Explore some of the East Bay's secret paths and staircases.
