Sal9000 on May 8, 12 at 09:36 AM. We spent 4 days in Lisbon and 2 1/2 in Porto. We thought the Porto time was about right to get an overview of the city. We made a list in advance of what we wanted to do in each city and found 4 days inadequate for everything we wanted to do in Lisbon.f we spend day 4 on transition to Lisbon visiting Coimbra on the way, we will have 5 full days for Lisbon: 3 days for the city and 2 days for day trips (Sintra, and a guided tour to Obidos, Nazare, Fatima and Batalha).
