The event runs from 3-7 p.m. Friday, Oct. 25 and from 12-7 p.m. Saturday, Oct. 26 aboard the Arthur Foss.

Find the perfect gourd for your sea-themed jack-o’-lantern in the Northwest Seaport’s floating pumpkin patch. Round up your little ghosts and goblins and set sail for the haunted Historic Ships Wharf at South Lake Union, where spooky fall fun for the whole family awaits. Pumpkins will be available for purchase to paint or carve (or bring your own).

Costumes are encouraged, and kids will be welcomed to trick or treat from boat to boat along the wharf.

Proceeds from this event will help support Northwest Seaport’s youth education programs.
