My husband and I are traveling with our 1 year old in Portugal for 2 weeks in September. We want to visit Porto/Douro area in the north but we also really want to spend some time on a beautiful beach where we can swim (ie. not too rough or cold). Is the Algarve the best place to find beaches good for swimming in September? Or are there similar beach options near Lisbon or Porto? We are planning to rent a car so can be flexible but will have a 1 year old with us. We are thinking of an itinerary that looks something like this:
Fly into Lisbon - stay 4 nights (include a day trip to Sintra)
2 days in Porto
2 days in Douro hillside
4 days in Algarve (or other beach)
1 day back near Lisbon (possibly stay in Palmela or Sintra or another place that will be a quick drive to the airport)
Fly out of Lisbon
Would love any thoughts/advice.
Thanks!
