Macnamara NatureTrail in Arnprior – Trail Report

Macnamara Nature Trail has been on my list for a while! And now that daylight lasts a little longer, I was able to skip out after work to go walk the trail for myself. It just so happened that it was on a magical winter wonderland of a day. Mild weather, buckets of snow, clear blues skies, and the sun shining bright – to be honest, it was a bit like walking through a children’s movie.

what to bring

Besides the 10 essentials and what I would normally suggest for hikes, here are the highlights for this particular hike:

  • Snowshoes: this is a wonderful trail with some mild elevation to enjoy snowshoeing.
  • A bird identification card: there is plenty to wander and observe on these trails.

Macnamara Nature Trail

The main loop of Macnamara Nature Trail takes you for 4kms with an additional 500m if you want to walk out to the marsh lookout. There’s also a newer 1.5km northern loop which means you can make this a 4km or 6+ km hike if you’d like!

This trail is rich in flora and fauna, on the winter day that I wandered around there were plenty of chickadees, nuthatches, and woodpeckers to view.

Points of interest on the Macnamara Nature Trail include:

  • Lime Kiln
  • Lady Slipper Orchids (early summer)
  • Boardwalks
  • Forestlands and marshlands
  • Streams
  • Lookout of Goodwin Marsh

Stops and Shops

Post hike stop included picking up a latte from Jack and the Bean Coffee House in Arnprior. This coffee shop is uniquely housed in The Gallery, so you can shop and view art while waiting on that latte.
