Glacier in January: what the park service says

January is when Glacier's ranger-led snowshoe walks begin. In the 2026 season the park ran them on Saturdays and Sundays at 1:00 pm from January 10 to March 15: two hours on snowshoes looking for signs of wildlife, not recommended for children under 6, and cancelled when West Glacier is forecast below 10°F. Walkers can rent snowshoes for $2 at the Apgar Visitor Center an hour before the start. Those are the only rentals in the park, so anyone skiing on their own brings gear from the towns outside. Most winter routes have no markers, so carry a map. Snowmobiles are banned everywhere in Glacier, and pets may not go on trails or unplowed roads.
