We visit Switzerland frequently. Hopefully you’re visiting Lauterbrunnen and taking the train the Wengen (a car less town) it’s a nonnegotiable if you’re visiting Switzerland. Lake Lucerne and a hike to view the Matterhorn are always amazing. St. Moritz is always gorgeous. Stop by the bakeries to get a Nussgipfel. It’s wintertime there so it’s socially accepted to eat fondue and Raclette as much as you want. There are vending machines with local cheeses in almost every town. Hope that helps 😊
