Whistler has an extensive paved trail network (40 km) connecting Whistler Village to all it’s neighbourhoods, lakes and other outdoor destinations. They’re open year round, so in addition to the usual walking, running, biking, skateboarding and rollerblading in the summer months, you can enjoy cross country skiing, snowshoeing and snowy winter walks in the winter months. Check out the official website link below and Whistler’s Hiking and Biking Map for all the details.
Unfortunately The Whistler Valley Trail is not off-leash, but the trails will take you to the Whistler off-leash dog parks.
