This Conservation Area provides an important access to the historic La Vase portage route for voyageurs travelling from the St. Lawrence to the interior of North America. The 11 km La Vase Portages are a series of three portages comprised of eight kilometers of waterway and three kilometers of pathway between Trout Lake and Lake Nipissing.  The route was used thousands of years ago by First Nations adn then by European explorers, soon becoming major transportation route.  NBMCA purchased teh property in 1995 with the assistance of the Ontario Heritage Foundation and a local Restore the Link Committee. Friends of La Vase offer an annual Canoe Day each July paddling and portaging the length of the trail.
