When you listen carefully, past the noise of the trains rolling on the tracks, past the cars whooshing by all around the urban setting, the sound you hear doesn't come from the subway's air vent. It's Mimico Creek in Thomas Riley Park. Kids will love to watch the TTC trains flash by over the viaduct (a sight we normally don't see up close!). As you walk past the lovely community garden by the southern entrance to the park off Bloor Street, you'll notice different small dirt trails reaching the creek. The ease of access of these paths varies but young explorers are bound to find one that suits their capabilities. Walking northbound on the winding paved trail running through the long and wide park, you'll reach a playground nicely set by tall trees. A bit further on the east side, you'll see a small bridge (where we saw many wild ducks). Adventurers who stroll along the dirt trail following the creek upstream will discover funky graffiti under another viaduct. This path leads to a second bridge to the northern entrance of the park. It will take you roughly 15 minutes to walk back to Bloor.
