When properly squished, ketchup packets rise above their humble hamburger-saucing origins to cover the earth with fearsome blood-red stains. Satisfy a horror-prone imagination with today's Groupon: for $10, you get one Monster Bash ticket (a $20 value) to The Haunted Hydro in Fremont. This Groupon is only valid on October 1, 2, 8, 9, 10, 15, 16, and 17.

After 20 years of successfully frightening fear fans, The Haunted Hydro is back for another season of shudders with more than 50 actors, multiple attractions, and an “Evil Inferno” theme. With a Monster Bash ticket, guests begin their journey by entering the 20-foot Tunnel of Terror leading to Hydro’s cursed chambers. Inside, realistically made-up monsters and mutants make screams scream in horror and force flesh to sprout goose feathers. Visitors can also venture into the brand-new Lair of Scare, a dark cavern of undeath where each turn is as futile as the one before it. A free paintball ticket gives brave citizens the chance to hunt the zombies that lurk in Paintball Alley, and a free soft drink soothes sore throats resulting from too much shrieking, screeching, and light- bulb eating.

The attractions open at 7:30 p.m. nightly, but true fearophiles can show up at 7 p.m. for the pre-show Ghoul-A-Bration, which features a “Monster Mash Birthday Bash” filled with choreographed dancing, fire eating, drumming, and more. Stop by the Crazy Bob Museum and Gift Shop to claim a free souvenir photo, and redeem the included $2 discount coupon for clothing, a tarot-card reading, or $2 worth of creepy feelings.

Recommended for ages 9 and up.


The Ohio Valley Haunts site gave Haunted Hydro an 8.5, and the haunted house boasts more than 400 Facebook fans.

  • Lots of make-up, tons of energy, and engaging dialogue, but not overly aggressive. – Ohio Valley Haunts
