Stellwagen Bank National Marine Sanctuary Visiting the Sanctuary Whalewatching allows humans a close encounter with large marine mammals. Most visitors to the Stellwagen Bank National Marine Sanctuary arrive via whalewatching or fishing vessels that depart from a number of coastal communities from north of Cape Ann to Cape Cod. Whalewatch vessel ports are Newburyport, Gloucester, Rockport, Salem, Boston, Quincy, Plymouth, Barnstable, and Provincetown.
Sanctuary boundaries begin three miles offshore from either cape.

The interactive show allows audience members to take pop quizzes and guide the outcome of the performance, which focuses on the difficult issues facing management of the marine environment, particularly the Stellwagen Bank National Marine Sanctuary.
