The Macnamara Nature Trail in the southeast corner of Arnprior is a window into the past and present natural world of the Lower Ottawa Valley. One of the MacNamara Field Naturalist Club’s largest projects to date, its boardwalks, viewing platforms, and benches – constructed entirely by volunteers – allow visitors to explore it without disturbing its wild character.
