The late Mary Sinish grew up in the Keweenaw, spending summers along the Portage Waterway on her family's land. Mrs. Sinish donated 40 acres to the Keweenaw Land Trust with the intention of making the land available to the public, especially children, to provide opportunities to learn about nature and enjoy the outdoors. Located near Oskar Bay, the nature area includes forested and shrubby areas with scattered wet meadows and dense cedar swamps. Upon her passing, Mary augmented the nature area and the quality of life for residents when she bequeathed to KLT an additional 16 acres, including 900 feet of shoreline on Portage Waterway. Mrs. Sinish's vision was to establish a nature retreat for those with limited access to the serenity of the outdoors. She envisioned a place where the elderly, children, scouts, artists, and groups who work with the disadvantaged could relax, learn, and enjoy all that nature offers.
The Marsin Nature Retreat has been home to family reunions, school field trips, organization retreats, workshops, small weddings and receptions, scout sleepovers, birthday parties, and many other diverse uses. If you would like to reserve a date for your event, please contact the Keweenaw Land Trust to organize a time right for you.
The Marsin Nature Area is open to the public year-round for low-impact recreation. Visitors can hike along the Portage Waterway, watching as the Ranger III ferry passes by during summer afternoons. Trails and boardwalks lead you through a dense cedar swamp, past long-term wetland research sites, and into an open meadow. A trailhead is located along Red Brick Road for day-use visitors. While the Retreat structures are available by reservation only, if no one is around we invite you to enjoy the lawn and lakeside views!
