If Halloween weekend snuck up and you need ways to celebrate, Long Beach has events for everyone in the family, from the smallest candy-seeker to the furriest critter. For family fun, Signal Hill is throwing its annual Halloween Carnival on Saturday, complete with games, candy and a costume parade. Little ones can transform into little zombies at Bixby Knolls’ annual zombie bike ride on Sunday, and all ages are welcome at two separate Día de Los Muertos kick-off celebrations at the Museum of Latin Art and Ranchos Los Cerritos.
