Winter on the Cascade Loop means warm fires, snowy treks, foggy waterfront views and joy! Whether your bliss is found riding a fat bike in the Methow, or catching a sleigh ride in Plain, winter welcomes you here! IMPORTANT: The North Cascades Highway closes in winter due to excessive snow, so note that when you plan to travel the Loop at this time of year, you need to plan to backtrack (which we actually love because it allows us to hit our favorite spots twice!)
