Marsin Nature Retreat is a welcome place for organizations, groups, families, and individuals in search of a place to gather and enjoy the environment around us along with all the basic amenities. This 40-acre nature area and the campus Retreat are available year round. With the help of our dedicated volunteers, we addied trails and a boardwalk through a white cedar swamp. This property not only allows access to the cedar swamp and surrounding lands, but it also gives access to water & shoreline. We are working to add to our native plant demonastration gardens and shoreline naturalization.

Planning your visit

We are allowing reservatioin for day use and overnight stays, however due to the lingering risk of COVID-19, visitors should clean to their satisfaction on arrival as well as leave the retreat cleaned for the next group. Marsin is a fully equipped house with working kitchen and bathrooms, 3 bedrooms and a large main room for large group activities. The yard is spacious and there is access for boats to enter the water. Kayaks and canoes are on campus along with paddles and lifejackets.

Why this place is special

The late Mary Sinish grew up in the Keweenaw, spending summers along the Portage Waterway on her family's land and visiting her grandfather and great-uncle. Inspired by this experience and those at a Wisconsin summer camp, she 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. A trailhead is located partway down Red Brick Road (see map)

Mrs. Sinish augmented the nature area and the quality of life for residents when she bequeathed to KLT an additional 16 acres, including her two homes along 900 feet of shoreline on Portage Waterway. Mary's vision was to establish a nature retreat for those with limited access to the serenity of the outdoors, a place where the elderly, children, scouts, artists, and groups who work with the disadvantaged could relax, learn, and enjoy all that nature offers.
