This Halloween night, call forth the spirit of the Flying Dutchman and its ghostly crew on the Haunted Ghost Ship party cruise. Put on your best costume and step aboard the Provincetown II for an unforgettable night on the water where you can celebrate the spookiest time of year. The ship offers stunning views of Boston Harbor and the inky-black moonlit ocean. Join the hair-raising costume party with dashing devils, gruesome ghouls and other hideous haunts of Halloween as you dance to music played by one of Boston's best DJs. You're sure to get thirsty, and fortunately there's a well-stocked cash bar.
