What to see: the monumental capital or the river city
Lisbon
Lisbon is organized into neighborhoods on hills: Alfama and St George’s Castle, the Baixa rebuilt on a grid after the 1755 earthquake down to Commerce Square, Chiado and Bairro Alto, then Belém, with the Jerónimos Monastery and the Belém Tower, both World Heritage sites. The museums (Gulbenkian, Azulejo, Ancient Art) and the Oceanarium in Parque das Nações easily fill rainy days. Sintra and its palaces, less than an hour away by train, justify an extra day. Our guide to visiting Lisbon lays out a 3-to-4-day itinerary.
Porto
Porto is concentrated around the Douro: the Ribeira and the Dom Luís I Bridge, the Vila Nova de Gaia cellars on the other bank, São Bento station and its azulejos, the Clérigos Tower and the Lello bookshop. Tram no. 1 goes to Foz, by the ocean, and Matosinhos is known for its grilled fish. Upriver, the World Heritage-listed Douro Valley can be explored by train, boat or car. Our guide to visiting Porto offers a 2-to-4-day program.
