With Halloween upon us, haunted houses across the country are opening their doors to families -- specifically those with teens -- looking for truly frightening fun. Here's our roundup of the best and scariest houses, all offering lots of shock, gore and special effects to scare and entertain.

Scream World in Texas
Screamworld, in Houston, right off the bat tells parents it is too intense and not recommended for children under 12 without a parent. It also says that young children may not be admitted. But for those who can enter, it is a screamfest. There are five exhibits: the outdoor Clown Asylum Maze, the Edge of Darkness, The Swamp, Jake's Slaughterhouse and the outdoor Zombie Graveyard. Screamworld is running Friday and Saturdays in late September, and then Thursdays through Sundays through October, with extra openings Monday, October 27 through Halloween, and a last Saturday on November 1.

Netherworld in Georgia

Netherworld in Norcross, a suburb of Atlanta, has been called the No. 1 Hometown Haunted House by Hauntworld and includes two haunts -- Season of the Witch and Spliced.

Erebus Haunted House in Michigan

Erebus Haunted House in Pontiac, Mich., is one of the world's largest walk-through haunted houses. The four-story frightfest takes one through Erebus, which is the path to Hell. The attraction begins operating the last two weekends in September, from 6 p.m. to 1 a.m., and then operates Wednesday through Sunday, remaining open nightly the week of Halloween through November 1. Sunday nights close at 11 p.m., and Monday through Thursday nights operate 7 to 11 p.m.

13th Floor Haunted House in Arizona, Colorado and Texas

13th Floor Haunted House takes the premise that even though many elevators do not have a 13th floor, there really is one! The 13th floor is where scary things happen and they do at this attraction with three locations: Phoenix, Denver and San Antonio. Unlike many of the other haunted houses, the 13th floor also features live animals and reptiles. The attraction suggests that if you wouldn't bring your child to a PG-13 rated movie, they shouldn't go to the 13th Floor, so caution is advised. The 13th Floor is open the last two weekends of September, then runs daily between October 2 through the first two weekends in November (with the exception of October 6).

Pirates of Emerson in California

Pirates of Emerson features six haunted attractions: Buried Alive, the Attic, Virus, Wild Woods, Pirates of Emerson and Mental Maze. Children of all ages are welcome but the Pleasanton, Calif., site warns about bringing "impressionable children." The attractions begin operating Saturday, September 27, then weekends beginning October 3, then adding Thursdays until the week of Halloween, where it is open the 29th through November 1. Hours are from 7:05 to 10 or 11 p.m. On Halloween, it is open until midnight. The Pirates of Emerson is located at the Alameda County Fairgrounds at the corner of Bernal and Valley Avenues. When it comes to bringing kids, they remind visitors the experience is "extremely frightening."

The Dent Schoolhouse in Ohio

The Dent Schoolhouse in Cincinnati is one of the most detailed haunted houses and gets its "haunted house" name honestly. The Dent Schoolhouse was actually a school that opened in 1894 and had a murderous janitor, Charlie, who was never caught and brought to justice. Is it he who haunts the halls of the school to this day? Among the rooms are Charlie's workshop, bedroom, boiler room and even the janitor's student holding cell. In addition, there is Detention Hall, which is an intense clown-themed maze. There is no age limit, however a Lights On Tour is available on October 28 for younger kids. The attraction opens September 14, operating Friday through Sunday through September and the first weekend in November, and then Thursday through Sunday in October, as well as Halloween. The November dates will be "Lights Out," where visitors will walk the attractions completely in the dark. On October, come dressed as the undead for Zombie Night. Hours begin at 7:30 through 10 p.m. and midnight on weekends.

Terror Behind the Walls in Pennsylvania

This haunted house is housed in a real, abandoned prison, Philadelphia's Eastern State Penitentiary, claimed to be one of the most haunted places in the country. The frightfest walks visitors through the grounds, cellblocks and common areas of the prison, which is eerie enough at night with its aging castle-like exterior. The attraction opens September 19 for weekends and then adds additional dates through November 8, always closed on Mondays. Kids under 7 are not permitted at the attraction, and kids 7 to 12 should visit on Family nights, offered every Sunday until 9 p.m. with a little less fright. (Kids are half price if you get there before 7:30 p.m.) Openings begin at 7 p.m., with a few Saturdays starting as early as 6:30 p.m.

Spooky World in New Hampshire

New Englanders looking for a scare can turn to Spooky World in Litchfield, which features five haunted attractions, a Monster Midway, live entertainment and more. Attractions include Brigham Manor, Freak Show in 3D, Carnage, The Colony and Raven's Claw. The attraction reminds parents to bring children at their discretion, but there will be blood, gore, scares and scary characters, as well as an attraction that shocks guests with electricity. Spooky World opens the last weekend in September and runs weekends through November 8, which is a Lights Out event in the dark. Weeknights are available in late October.
