Welcome!

  The Grand Traverse Bay Underwater Preserve is the state of Michigan's 12th designated underwater preserve. The GTBUP encompasses the east and west arms of Grand Traverse Bay from Cathead Bay in the northwest over to Norwood in the northeast.

  The waters of the GTBUP contain shipwrecks from the 1800s up to the 1970s, historically significant cultural sites such as one of the oldest dock remains in Michigan, as well as fun dive sites like a 1970s Ford Pinto.

  Please email us on the contact page for more information. Also, look for us on facebook.

  The GTBUP has recently redesigned its website to make the viewing of photographs and videos easier as well as offering a fresh new look. Please bear with us as some sections are currently under construction.
