The event is known as the East Coast Haunters Convention and pairs with the adjacent East Coast Christmas Show.
It continues on Sunday, April 26, 2026 from 10:00am-3:00pm.
The event is expected to return the last weekend of April each year.
Hosted by TransWorld Trade Shows, this convention is an off-shoot of their large commercial event.
Now in its third year, the event in Oaks brings out enthusiasts to discover new technology, intricate art and makeup stylings, and unique decorations.
Earlier this weekend, they hosted bus tours of local attractions such as Lincoln Mill Haunted House and Pennhurst Asylum.
Action News joined Lincoln Mill Friday afternoon as they brought their actors back and put on a full off-season show for guests.
