There are several easy ways to get to Long Beach from Orange County if you don't have a car. The most direct way is to take Orange County Transit Authority's Route 50 bus servicing Katella Avenue, which passes between Disneyland and the Anaheim Convention Center. The western terminus of this route is Cal State U-Long Beach. If you are in the Beach Cities, take Route 1 servicing the Pacific Coast Highway and also terminating at CSULB. Alternatively, you can also take Amtrak's Pacific Surfliner or Metrolink's Orange County Line to LA Union Station and transfer to Metro Rail as already described.
