We are an active in our mid 50s and will be visiting Portugal for the first time for 10 days in the last part of February. We will be flying in an out of Lisbon (from the US). We love seeing picturesque towns, good food and wine. On our list is Lisbon, Porto and the Douro valley. Not sure we can squeeze in the Algarve? Would appreciate any itinerary suggestions. Thanks in advance
My wife and I visited Portugal in Aug 2023, staying 10 nights. We flew into Porto and out of Lisbon. Our trip report might have some useful info to your planning: https://community.ricksteves.com/travel-forum/trip-reports/trip-report-portugal-aug-sep-porto-coimbra-lisbon-then-to-spain
