If fat biking is one of the hottest and newest winter sports, snowshoeing is the world’s oldest. The earliest snowshoes are believed to have been invented more than 4,000 years ago, but at Galena Lodge and Sun Valley Resort’s Trail Creek Nordic Center you can step into a pair that represents the state of the art and go for a wander. Grab a $5 pass and explore trails that weave through meadows and pine forests, offering breathtaking views of the area’s pristine alpine peaks. Both locations can rent you all the equipment you’ll need, as well as give you an overview of how to walk with tennis rackets strapped to your feet. If your canine companion is a fan of the snow, he’s welcome too.
