Trunk or Treat

Pumpkin Festivals

Scarecrow Festivals

Haunted Houses


SAN DIEGO - San Diego Gaslamp Quarter Monster Bash. The streets of the ill-reputed Gaslamp Quarter bring out the wild and unimaginable souls. Costume contest, blocks of bands, parties, costumes. It's incredible!

WEST HOLLYWOOD - Carnaval attracts over 500,000 people some years to the single biggest street Halloween event in the world! the free event is open to the public and you are invited to attend on October 31, each year.

Ideally, you should see both theme park scares this year because they're going to be great!

After you've done Knott's and Universal, don't miss some hidden gems. Queen Mary's Dark Harbor was created by a former Knott's employee and uses some of the great tricks of the trade that are proven. Any place that has an authentic, haunted space (Queen Mary ship) as part of their haunt is worth the admission. In that same vein, the Winchester haunted mansion in San Jose is the real deal offering Halloween thrills, though guests are always kept corraled due to the nature of the haunted mansion, its age, collections, and valuables.

For kiddie theme park thrills, the king of scare (Knott's) has a Camp Snoopy event for kids. The happiest place on earth, Disneyland, wins honors for knowing its audience and creating a family oriented event with trick-or-treats for all ages, and a spectacular fireworks show just for Halloween.

There are two Six Flags theme parks in California (Valencia & Vallejo) and both will offer events of some sort for Halloween, though their mantra on a daily basis is "scare". Pirates of Emerson is one of the bigger draws in the Bay Area and is located in Pleasanton.
