Halloween falls on a Monday this year, but don't think that's going to stop the Bay Area from partying harder than ever. We've rounded up some of the best parties, family events and even cruises going down this weekend. Hope you have your costume ready!

FAMILY FUN

Pets and their humans are invited to celebrate Halloween on the Oakland waterfront with tricks, treats, frights and delights for humans and four-legged friends alike. The Jack London Square festivities include paw painting for pups, pet pampering, a pet psychic, pooch photo booths, doggy treats and more! // Saturday, Oct. 29, 11am-4pm, Jack London Square (Oakland), jacklondonsquare.com

Costume Dash 5K

Hoards of costumed runners will take part in a 5K in Golden Gate Park this month. Will you be one of them? Once you cross the finish line, the fun continues with an after party at the park, featuring a costume contest and free gifts from this year's sponsors. Some of last year's best costumes included a California sushi roll and Oscar the Grouch from Sesame Street (with his garbage can and garbage man in tow). // Sunday, Oct. 30, Golden Gate Park, costumedash.com

Halloween Haunt at Great America

Since 2007, Great America's Halloween Haunt has produced a variety of rides and shows that are as entertaining as they are terrifying. This year, take a spin on the Delirium, a powerful pendulum that promises to send you whirling into the night or check out the CornSTALKERS maze, where you'll need to weave your way through hay bales and cornstalks while being chased by a cult of evil scarecrows. // Oct. 14 - 29, 7pm - 1am, 4701 Great American Parkway (Santa Clara), cagreatamerica.com/haunt

Phantasm: Behind the Funhouse Door @ The Armory

Ready to celebrate Halloween with a few drinks? What about a few drinks three nights in a row? The Halloween Pub Crawl will start at Bar None on Union Street and continue all through the night. If you can't make it on Friday or want to keep the fun going, the pub crawl will take place again on both the 29th and the 31st, stopping at half a dozen of San Francisco's hottest bars. Domestic drafts will be as cheap as $2, well drinks will be $3 and shots will be $4. Costumes are encouraged! // Oct. 28 - 31, 1980 Union Street (Cow Hollow), pubcrawls.com

Halloween International Ball @ the Westin St. Francis Hotel

There's almost something spooky about spending the night in a historic hotel like the Westin St. Francis, the site of the infamous Fatty Arbuckle manslaughter scandal of the 1920s and President Ford's attempted assassination in 1975. On October 29, the St. Francis is opening its doors to costumed partiers who can dance their way through four separate rooms, each with its own musical vibe. With DJs spinning everything from '80s and '90s throwbacks to Latin grooves, there's bound to be something for every witch, astronaut, and Donald Trump imitator. // Saturday, Oct. 29, 9pm - 2am, 335 Powell Street (Union Square), eventbrite.com

Clift Horror Story Hotel

The famouslyseductive Redwood Room at the Clift Hotel will be transformed into a shadowy netherworld in celebration of Halloween. Moving portraits and mysterious characters will lure you in and tunes by musical duoJ Boogie & Deejay Theory will make you want to hang around. You know, like ghosts do. // Saturday, Oct. 29, 9pm - 2am, 495 Geary St. (Union Square), backofhouse.morganshotelgroup.com
