On the northeastern riverfront lies the Parque das Nações. Built for Expo 98, the development includes a huge world-of-its-own aquarium, the Oceanário, plus the Pavilhão do Conhecimento, and a landscaped riverside park with restaurants and bars. There's some stunning modern architecture here: the ribbed Death Star structure of Gare do Oriente and the Pavilhão de Portugal by Portugal's leading architect, Álvaro Siza Vieira.
A riverside teleférico, more than 0.6 miles (1 kilometer) long and 66 ft (20 m) high, gives stunning views of the river and the Vasco da Gama bridge. The 1.2 mi (2 km) long park site sometimes feels as if you have wandered into an architectural model, but it's an entertaining place to visit, particularly for families. A mini-train trundles around hourly, and you can even rent bikes.
We did two tours Lisbon day tour and Sintra tour. Both were well organized and informative. The tours guides are extremely knowledgable and enthusiastic about their city. Our guides, Michaela and Miguel really gave a personalized service. We were picked up at our hotel and the small group format was perfect for us. We managed to see a great deal in a relatively short period of time. The little extras such as suggestions for lunch, shopping and pastries gave us more insight into the culture. Would highly recommend this company.
We were lucky to have Mihaela, our guide, for ourselves as there were only 2 of us. She went out of her way to please us and answer all our questions. Shes very down to earth and knowledgeable about the sites we visited. We enjoyed ourselves and were satisfied with the service.
Very nice day with very attentive guide
Take the metro to Gare do Oriente and walk through the Centro Vasco da Gama to the park's main Posto de Informação, with free maps and information. The Cartão do Parque gives admission to the Oceanário, Pavilhão do Conhecimento, cable car and Vasco da Gama tower, as well as some restaurant discounts.
