With Halloween just around the corner, Castro Valley Patch is helping out the trick-or-treaters by hunting down some of the best-decorated houses in the area.

Above, you'll find an interactive map where you can add addresses and photos of local houses featuring some frightful and festive Halloween decor.

From the Haunted Garage on Forest Avenue to Columbia Manor on Columbia Drive, we've included a few already. However, we would like your help in finding some other houses decked out for the horrific holiday.

Do you know of a neighborhood or business that goes all out during Halloween? You can click the "add" button on the map to post a marker. You may also add photos and a description of the houses. Or, you can add photos to our photo gallery by clicking the "manage photos and videos" button.

Hope you have a good scream this Halloween! Mwuhahaha...
