Your dog keeps you company, and he/she is a great magnet for social banter with strangers you meet on the trails.
I was delighted to find Sépaq has opened 4 doggy-
on-leash trails in Oka Park along with Frontenac Park in St-François (250 kilometres form Montreal) and Jacques-Cartier Park in Longueil (a mere metro/bus ride away from Montreal).
Winter's coming. The park has six ski trails totaling more than 35 kilometres!
