Sea to Sky Highway Traffic Advisory

With GranFondo 2026 coming up on September 12, you can expect to see over 5,500 cyclists cycling along the roads. Potential delays may occur from 5:30am to 4:00pm between Stanley Park, through the Lion’s Gate, through West Vancouver and Squamish, to Whistler, so it’s best to know where the event will be happening throughout the city– and out of it.
