  description: The Zoo at Presque Isle is the crown jewel of Great Lakes surfing—a reef break in a sheltered bay that produces remarkably clean waves when northerly storms sweep across Lake Superior. Named for a historic zoo that once stood nearby, this spot benefits from Superior's deep water and long fetch, generating swells up to 12 feet in major storms. The local crew is dedicated and welcoming, braving sub-zero temperatures in full winter gear. When the wind shifts offshore and the swell lines up, The Zoo delivers wave quality that rivals ocean spots.
