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).
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. The KLT has made substantial
progress towards this vision and the Marsin Nature
Retreat is now a welcome place for organizations,
groups, families, and individuals in search of a
place to gather and enjoy the environment around us.

more about the space and how you can stay here.
The 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.
