Bete Grise Wetlands Preserve

Bete Grise is the highest quality dune and swale wetland system remaining in the Upper Great Lakes.



Located in the beautiful Michigan Keweenaw, Bete Grise boasts nearly one and a half miles of high-quality sand beach along Lake Superior, possibly the longest in the Keweenaw. This entire beach area was slated for a housing development in the early 2000s. But, after many public meetings and negotiation, the property was set aside for conservation, opening the beach to the public.

The 62-acre Bete Grise Wetlands Preserves consists of just over 4,000 feet of sandy shoreline along Lake Superior leading to dune and swale wetlands, and 1,000 feet of frontage on the Mendota Ship Canal.

Look to the skies (and treetops) to spot the common loon, merlin, and bald eagle. Many species of special plants are found in the wetland areas of the preserve. Enjoy warm sunny beaches in the late summer months, and be on the look-out for vibrant beach glass!
