Although there are plenty of Halloween events in the Capital Region that are appropriate for all ages, especially families, there are also several adult-only celebrations in northern Virginia, Maryland, and Washington, D.C. at the end of October and in early November this year.

If you're traveling to the area this Halloween (or Day of the Dead) season without kids and looking for a place to get dressed up in fun or scary costumes, these parties, events, and festivals offer everything from drinking and dancing to out-of-this-world terrors in honor of the haunted holiday. However, be sure to check each event's website for information about ticketing, attendance guidelines like dress codes, and up-to-date information about the party itself.

The Giant Halloween Graveyard Jam

The Giant Halloween Graveyard Jam is one of the biggest adult holiday dance parties happening in Washington, D.C. this October. Hosted by Things to Do D.C. on the last Saturday night in October each year, the Graveyard Jam is a huge party featuring a costume contest with prizes including a trip to the Carribean, DJ music, and dancing.

Throughout the night, guests will also have access to other entertainment options like pumpkin party games, free drawings done by a caricaturist from Frankenstein's Castle, and tons of giveaways. While costumes are not required to attend, you'll be sorely out of place among the thousand costumed guests if you don't dress up.

For information about ticketing, hours, and location of this year's event, visit the official Things to Do D.C. Facebook page closer to the last weekend in October.
