(Approx 1.5 km return) For a taste of Grassy Narrows Marsh, the Chorus Frog trail offers the best variety. Start out walking through dense willows into a rare copse of ash and oak before finally reaching the expanse of the marsh. A short boardwalk takes you to a viewing blind from which you can spot pied-billed grebes and if you’re lucky, the flash of an otter. For a longer walk back, take a left just off the boardwalk and follow the dyke along the marsh’s edge and reconnect with the entrance road to take you back to the trail-head.
