Swim Across the Bay is a point-to-point swim event that begins at Henderson Point Boat Launch in Pass Christian, Mississippi, and finishes at the Bay St. Louis Municipal Harbor. Participants have a set period to complete the swim, with award recognition for the top finishers. Safety measures allow for the use of personal buoys and snorkels, and goggles are strongly recommended. A shuttle service connects the start and finish points for convenience. Volunteers, particularly those with kayaks, are needed to support the swimmers. All participants and volunteers receive an event shirt, and refreshments are provided post-race.
