Visitors can access the TNC preserve by walking along the beach through the Houghton Keweenaw Conservation District’s Bete Grise Preserve.



The 62-acre Bete Grise Wetlands Preserve consists of just over 4,000 feet of sandy shoreline along Lake Superior leading to dune and swale wetlands. 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 lookout for vibrant beach glass!



Pets are not permitted. Please do not trespass on private residences.


This land is open for foot access and activities such as hiking, snowshoeing, bird watching and swimming.

TNC's Work in the Keweenaw

Bete Grise is located in the Keweenaw Peninsula, an area TNC has been active in for decades. The Keweenaw has globally significant opportunities for nature-based carbon solutions and land and water protection, all contributing to the health of one of the world’s largest freshwater systems, the 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 negotiations, the property was set aside for conservation, opening the beach to the public.
