What Is the Macnamara Nature Trail and How Do I Visit It?
Updated
The Macnamara Nature Trail is a nature trail in Arnprior, Ontario, maintained by the Macnamara Field Naturalists' Club. It is the club's largest project, and its boardwalks, viewing platforms, and benches are designed to let visitors explore the area "without disturbing its wild character." A newer 1.5 km extension improves observation of the wetland by Goodwin Bay. If you want to walk it, the club publishes a trail guide and supporting resources on its website, and the trail is open to visitors rather than being a members-only facility.
Where the trail is and what makes it notable
The trail is located in Arnprior, in the Ottawa Valley. The club describes it as "a window into the past and present natural world of the region."
Its significance comes from two things:
- It is the club's flagship project. Of everything the Macnamara Field Naturalists' Club does, the trail is described as its largest undertaking.
- It is built for low-impact access. Boardwalks, viewing platforms, and benches carry visitors over and alongside sensitive ground rather than through it.
The club itself was formed in 1984 by naturalists in the Ottawa Valley and follows in the footsteps of Charles Macnamara (1881–1944), a naturalist and photographer who lived in Arnprior.

How to plan a visit
- Start with the club's trail pages. The website has a dedicated Macnamara Nature Trail section plus a Macnamara Trail Guide. Read the guide before you go so you know what you are looking at.
- Check the supporting resources. The site also hosts material on the trail's geology and field guides, which help interpret the terrain and the species you may encounter.
- Look at recent sightings if wildlife is your goal. The club maintains a sightings section with monthly entries (for example, Sightings – December 2024 and earlier months), plus a Christmas Bird Count page. These give a sense of what has been observed and when.
- Time your visit to the season you care about. The club's field trips cover everything from geology to migrating birds to rare orchids, which indicates the range of natural features across the year.
- Walk with the trail's purpose in mind. The boardwalks and platforms exist so visitors can observe without disturbing the wetland and surrounding habitat — stay on the built surfaces and use the platforms as your viewing points.
What to expect and how to get more involved
The trail is a self-guided outdoor experience rather than a staffed attraction. The club's role is to maintain it and to publish guides and records that help you interpret it.
If the trail interests you, the club also runs expert speaker meetings, field trips throughout the year, an annual banquet and silent auction, and a trail committee. Membership and joining information is available on the site, and the club has a "Help Extend the Macnamara Trail!" appeal for those who want to support the trail directly.
