Halloween season means a lot of things: trick or treating, fun costumes, and of course the best parties of the year. Year after after, one of the Houston area’s best Halloween parties is held at the Houston Museum of Natural Science. The Spirits and Skeletons Halloween Mixer invites guests into the museum for a night of tricks and treats, music and food – and loads of bars of course. To make this night even better, Groupon is currently offering tickets for 30% off. If you want to take part in the best party of the year, you better get your tickets fast, because they’re sure to sell out.

Houston’s favorite Halloween party returns this year to welcome Houstonians into the museum to party right beneath the dinosaur skeletons. Live music will be provided this year by DJ Dame Hype and Supernova, while this year’s food trucks will be Nom Mi Street, Waffle Bus, D’Lish, Foreign Policy, and Moon Roosters. Tickets usually start at $25 for members and $50 for adults, but you can get admission for one for just $30 right now through Groupon. Better hurry – sales have been capped at 9,000 tickets this year due to the growing popularity of Houston’s best Halloween party.

Latha Thomas, vice president of marketing and communications at the Houston Museum of Natural Science, says the party offers a one-of-a-kind experience for Houstonians. “It’s a very unique Halloween event because the entire museum is open, so all four floors of the exhibit halls are open,” Thomas says. “We have live music, three DJs, over 30 bars, a magician, five food trucks outside; it’s really a way for you to see the museum in a different light. Almost everybody is in costume; it’s remarkable.”

The Spirits & Skeletons Halloween Mixer will be held Saturday, October 27th from 8:00 p.m. to midnight. The party is for trick-or-treaters aged 21 and up only, so leave the little ones at home.
