There is an old cliché about good things coming in small packages, and nowhere is it truer than inside the 988 square miles of Luxembourg. This little country wedged between France, Germany, and Belgium has the highest GDP per capita in Europe, and though the abundance of countryside castles aren’t a direct reflection of that, they certainly add to the sense of luxury.
Head out to the lush Ardennes Forest and find the castles hidden among the trees, like a storybook set right in your vacation. Then head into the capital in Luxembourg City and try some unique Luxembourgian cuisine, heavily influenced by French techniques and German portions. You can burn it all off along the Mullerthal Trail, a 70-mile loop through waterfalls, swimming holes, and a dense canopy of trees.
