Traverse City
One of the smaller ones on this list, Traverse City is stunningly beautiful in the summer. I’d recommend timing out your visit with the Cherry Festival which brings out the best in local products. Regardless of when you go, think about doing a winery tour or two as well: the area is getting known globally for producing some of the best wine in the US, and the drives between wineries are often along some of the most picturesque scenes I’ve ever seen.
