Pennock Creek Trail is more popularly known as the 25th Side Road Tree Farm. It’s one of those places you drive by all the time without realizing that there is such a big green area just out of sight.
Drive west on Arthur Street until you cross the train overpass then turn left onto 25th Side Road. Drive .9km and turn right into the parking area just before you come to Veradale Street. There is also another parking area on the right just past Veradale Street at the main MNR buildings. You can get onto the trail from either parking lot.
You can follow the white and green Pennock Creek Trail signs or you can choose your own route through the maze of rows that make up the tree farm. The Pennock Creek Trail features the Pennock Creek itself , benches, bridges, a dam, a butterfly garden and interpretive signs.

I lived in Thunder Bay for 3 years and the tree farm was my absolute favorite place. My dogs and I loved it. My fiance even proposed to me there under the beautiful trees:)
