You can look up your congressional district at http://www.house.gov using your zipcode.
You can then look up your caucus location at http://www.ca-dem.org/caucuses.php
You do NOT need to be registered to vote to walk in the door. You can fill out a registration form on-site.
Each candidate has a different caucus location. You can show up at the location of someone you're considering as a candidate, talk to supporters, and decide whether or not to join in with their support.
The doors shut and the caucus starts at 3 p.m. You don't have to stay for the whole thing, you can vote and leave.
From the Democratic Party's Caucus FAQ:
WHAT TIME DO THE CAUCUSES START?
For each presidential candidate in each of California’s 53 congressional districts doors open by 2:00pm and the Caucus begins at 3:00pm. You must arrive by 3pm to participate in the caucus.
WHO CAN PARTICIPATE?
All caucuses are open to registered Democrats, campaign supporters and the media. People residing in that CD may also register to vote on-site.
WHO CAN VOTE?
Any registered Democrat who resides in the Congressional District in which the caucus is being held and signs a pledge of support for that particular presidential candidate by 3:00pm may participate as a voter. Democrats go to the caucus of the presidential candidate they are supporting, and therefore cannot attend more then one caucus.
CAN PEOPLE REGISTER / RE-REGISTER TO VOTE AT THE CAUCUS?
Yes. Each caucus should have voter registration cards available.
MUST I STAY UNTIL THE END OF THE CAUCUS?
No. Voters are not required to stay during the entire Caucus. As soon as the doors open and registration begins, a person can register, vote, and leave.
WHO RUNS THE CAUCUSES?
The presidential campaigns run their own caucuses under uniform guidelines set by the Democratic Party and the Delegate Selection Plan.
