Travelers can get around via tram, bus or metro in the city centers. Day tours to Sintra's palaces and gardens will cost around 20 EUR per person. To get to Albufeira for Day 3, take a train from Lisbon to Albufeira for around 25 EUR per person.
In case of more time, don't miss out on the Oceanário de Lisboa, one of the largest marine aquariums in the world or explore the Castelo de Sao Jorge, a Moorish castle overlooking the city. If there's less time, cut down on Day 2's beach and seafood itinerary.
Lisbon Portela Airport (LIS) is the main international airport, located 7 km from Lisbon. It has easy access to the city center via metro or bus.
