Maybe because for many in the northern states, it's a chance to do one more trip before the RV has to be winterized and put in storage.

Instead of just one night – Oct. 31 – many parks dedicate the entire two or three weekends (or more) before Halloween.

That's why now is the best time to plan for your Halloween adventures. I've put together a list of some of the best places for Halloween camping across the U.S. (based on my own experiences and lists from others, including DoItYourselfRV and Active.com).

1. Kentucky Horse Park, Lexington, Kentucky

The place sells out every weekend in October and to get a spot, many campers had to book their sites a year in advance.

Every year, about 1,500 people visit to take part in the festivities and activities that run all day long.

Several years ago, Jennifer and I visited it on a Wednesday and Thursday and found the place half full already by early birds – Halloween campers who have so much fun stay for weeks at a time.

At night, their motorhomes, fifth wheels, truck campers, and travel trailers are strung with lights and spooky decorations.

There are paper mache spiders, witches, werewolves, skeletons, headless horsemen, and elaborately carved pumpkins.

Cobwebs are strung between trees, tombstones sprout from the ground, ghostly sheets wave in the breeze. The park provides inflatables that can be borrowed as well.

There are costume parades and contests, wagon rides, music, barbecue, and campfire socializing.
