Thunder Bay Maritime Festival
Bring the whole family to this free annual community event hosted by the Thunder Bay National Marine Sanctuary.  Since 2001 the sanctuary has encouraged thousands of visitors to dive deeper into the maritime world at this celebration of all things nautical.  Walk along the Thunder Bay River's Great Lakes Maritime Heritage Trail and see local and visiting boats.  Watch the annual Cardboard Boat Regatta  in the river or enter with your own team!  Enjoy live music on the main stage, kids activities and crafts, pilot a remotely operated vehicle (ROV), taste some local whitefish, explore the Shipwreck Century exhibits and more! 

Contact: Jean Prevo, (989) 884-6208,

Festivities start each year at 500 W. Fletcher Street following the 4th of July parade in downtown Alpena.  See our event calendar for this year's hours.
