Switzerland: Pack smart

Bring a warm sweater. Even in July and August the evening air grows chilly in the mountains. And bring a hat or sunscreen, as the atmosphere is thinner at high altitudes. Glaciers can be blinding in the sun, so be sure to bring sunglasses, especially for high-altitude excursions. Good walking shoes or hiking boots are a must, whether you’re tackling medieval cobblestones or mountain trails.
