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 usĀ along with all the basic amenities.This 40-acre nature area is available year round from the trailhead on Red Brick Road. With the help of our dedicated volunteers, we are adding trails and a boardwalk through a high quality white cedar swamp to connect the existing trail network with the lakeshore campus and Retreat. This property not only allows access to the cedar swamp and surrounding lands, but it also give access to water & shoreline.

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, 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. 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. 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.
