The length of the skating trail at The Forks changes each year, depending on river and ice conditions, although a concerted effort is made to make it as long as possible. In the winter of 2010/2011, conditions on The Assiniboine River made it impossible to safely create skating westward, so the path extended instead south on the Red River. Essentially, the water level and the weather at the time of freeze-up will impact the way the ice forms (see frazil ice, for example), how stable it will be, and how smoothly it can be made for skating. Much of the local river ice in Winnipeg in the winter of 2010/2011 was too rough to form a skating surface. There is also a skating trail made overland which is not impacted by river conditions. There are also walking and ski trails running parallel to the skating trail.
