The Destination
Welcome to Portugal, one of the oldest countries in Europe and a paradise for sea lovers.
With half of its territory bordering the Atlantic Ocean, Portugal is a prime location to study aquatic ecosystems. It is home to the largest fully protected marine reserve in Europe and is packed with wildlife-filled wetlands, sandy beaches, and dramatic riverways.
Portugal is also full of rich history. When you are not enjoying its natural landscapes and biodiversity, you can lose yourself in incredible architecture, medieval castles, and numerous UNESCO World Heritage Sites. Lisbon, the capital of Portugal and your home for three weeks, is more ancient than Rome. Here, you’ll love riding the old cable cars up the steep hills, admiring the buildings covered in tiles of countless colors and patterns, and basking in the spectacular views of the vibrant city.
Magical Portugal—with its sunny cities, sea breezes, beautiful beaches, friendly people, and delicious food—awaits you!
