SaveThe bulk of purpose built mountain bike single-track trails are found in the area know as Shuniah Mines, within Trowbridge Forest. Approximately 21km of trail winds it’s way through the old silver mining grounds taking full advantage of the unique topography of tailings piles, rock features and a series of small ridge lines. Be on the lookout for signature trails as Grand Chasm, Dagobah, Doctors and a downhill progressive flow lines; Drift and Hilltop Trail. The area is best known for natural, hand carved tread with plenty of rocks and roots. For those looking to take full advantage of the rugged boreal forest landscape make sure to check out Snakes & Ladders or The Otherside.
The best way to access our trails is to park at Kinsman Park at Trowbridge Falls, from here you can jump on your bike and follow the gravel path until you reach a bridge. Once you cross the bridge, you will see Conveyor Belt directly ahead of you. Conveyor Belt will take you directly to the heart of Shuniah Mines where you can access all of our trails.
The centre of Thunder Bay hosts a large system of multi-use trails; both paved and gravel. Many of these trails link the greenways along the McIntyre river, Needbing river and Current river. As well the city continues to expand the trails along the coast of Lake Superior in Prince Arthur Landing (central Port Arthur).
