If you’re passing through the foothills of the California Sierra Nevada during the last two weekends of October and hear a lot of screaming, don’t panic.

You could be hearing participants in this year’s “best scream” contest, one of several Halloween themed events taking place at Far Horizons 49er Village RV Resort in Plymouth, Calif., according to a news release from the National Association of RV Parks and Campgrounds (ARVC).

“Both weekends are sold out,” said Sue Trimble, office manager for the 329-site campground.

These aren’t your ordinary camping enthusiasts, mind you. The camping and RVing enthusiasts who book their sites during the last two weekends of October come with friends and family members and create their own haunted campsites.

“Sometimes groups of people will come and they’ll use two or three campsites and invite everyone in the campground to come in and visit their haunted RVs,” Trimble said.

The campground also invites drama students from neighboring Amador High School to come over and read scary stories to the younger campers.

Sound extreme?

“You’d be surprised to know what campground operators are doing at this time of year,” said Linda Profaizer, ARVC president and CEO.

“Instead of letting Labor Day be their last hurrah, many campground owners have discovered that they can keep having busy weekends right on through September and October, particularly if they have Halloween oriented activities.”

Campgrounds affiliated with Kampgrounds of America Inc. (KOA) and Yogi Bear’s Jellystone Park Camp-Resorts have been offering Halloween oriented activities for years. But independently owned and operated campgrounds are also increasingly getting into the act.

“October is our busiest month,” said Dana Gabriel, co-owner of the Jellystone Park in Swansea, S.C.

The last three weekends in October, however, are when the park gets really scary, with a “Darkwood Plantation.” Guests start their adventure visiting a haunted plantation house, then proceed into the gardens, a cemetery and a swamp where there is a voodoo witch.

“We have a mix of static props, animatronics and 10 or 15 actors who make it a pretty scary place,” Gabriel said.

The Winston-Salem KOA in Statesville, N.C. has generated a similar following with its “Midway Wicked Woods,” a frightening walk in the woods. “It is very scary,” said Jocelyn Hogue, a park manager, adding that the haunted trail is open to campers as well as the general public.

Of course, campground operators aren’t limiting themselves to Halloween themed activities. Many also offer other activities and entertainment, such as fall harvest festivals, Western themed weekends and Oktoberfest celebrations.

Some campgrounds also offer corn mazes, including the Jellystone Park in Sioux Falls, S.D., which offers a seven-acre corn maze, with an easy section for young children and a more difficult section for teenagers and adults.
