Life-Changing Experience
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!
Cultural Awareness
CIEE wants all our students to feel welcomed, supported, and empowered to succeed while studying abroad. Local CIEE staff have provided details about conditions and cultural attitudes that students with specific identities might encounter in Lisbon.
Weekly Learning Goals
Settle into Lisbon. Investigate species and attributes of river, estuary, coastal and offshore marine ecosystems, human impacts, and habitat threats. Travel to the Tagus River to observe a riverine ecosystem firsthand and conduct experiments. Choose a local environmental challenge for your Project.
Examine the rocky intertidal zone at Avencas beach, observe the aquatic bird populations at Lagoa Pequena, and participate in dune restoration with a local NGO. Research and assess the interdependence of local economies, human activities, and conservation of marine ecosystems. Apply insights to your Project.
Go snorkeling and observe the marine biodiversity in Arrábida Natural Park. Investigate ocean sounds and animal communication. Take a boat ride to survey and report dolphin sightings. Consider all you’ve learned as you tour Lisbon’s Oceanarium and see how its foundation carries out conservation work. Present your Project.
