It is not Spanish. Portuguese is its own language and saying gracias instead of obrigado lands badly. Obrigado if you are male, obrigada if you are female. Learn those, plus bom dia, and you are fine.

Meals run late but not Spain late. Lunch around one, dinner from seven thirty. You can eat at seven with kids in most places and nobody blinks.

The couvert is not free. The bread, olives and cheese that appear on your table are charged if you eat them. Push the plate away if you do not want it. Nobody is offended.

Volume is low. Portuguese restaurants and trains are quieter than Spanish or Italian ones. Loud American family is a real look and we work on this constantly.

Older people get deference. Give up the seat. Let them go first in the queue. Kids who do this get treated very well in return.

Fado is not background music. In a fado house you sit still and stay quiet while somebody sings. It is not a dinner show. Bring kids who can handle forty minutes of silence, or do not bring them.

Euro. Portugal is in the eurozone. Cards work almost everywhere, but carry twenty or thirty in cash for markets, small cafes and the tram.

Schengen. Americans get ninety days in any one eighty across the whole zone. Portugal draws down the same clock as Spain, France and Italy. Watch it if you are doing a long Europe run.

Tipping is small. Round up, or five to ten percent for a proper sit down meal. There is no twenty percent expectation and adding it marks you out.

VAT refunds are real. Twenty three percent is already baked into the price. Spend over about fifty euros in one shop and you can claim it back at the airport if you fill in the form at the till.

City tax. Lisbon and Porto charge a couple of euros per adult per night, collected at the hotel and not included in your booking total. Small, but budget for it.

eSIM before you fly. Ten to fifteen dollars for a week of data. Do it at home, not standing at the airport.

Tap water is fine. It tastes slightly mineral in the south. Bring bottles and refill them.

Five days. Lisbon plus one day in Sintra. That is it. Do not add Porto.

Seven to eight days. Lisbon three nights, Sintra as a day trip, train up to Porto, Porto three nights. This is the classic and it works.

Ten to twelve days. Add the Algarve on the end, or add the Douro instead if you want quiet over beach. One or the other, not both.

Two weeks or more. Now Madeira or the Azores earns its flight, or you drive the Alentejo slowly between Lisbon and the south coast.

What not to do. Lisbon, Porto, the Algarve and Madeira in ten days. I get asked for this every spring. It is four unpacks and two flights and you will mostly see airports.

Lisbon. Base the trip here. Alfama for the old streets and the fado, Belem for the tower and the monastery and the original pastel de nata, and the miradouros, the viewpoints, which is where the city actually happens in the evening. Tram 28 is famous, packed, and a pickpocket favourite. Ride it at opening or ride the 12 instead.

Sintra. Forty minutes out by train. Pena Palace on the hill looks like a child painted it, which is exactly why kids love it. Book timed entry, go at opening, and pick two sites rather than four. The whole valley is a traffic jam by eleven.

Porto. Smaller, steeper and grittier than Lisbon in a way I think families actually prefer. The Douro riverfront, the double deck bridge, the port lodges on the far bank. Two full days is right.

The Douro Valley. Terraced vineyards stacked on both sides of a green river. This is the river cruise route and the one I sell. By land you can do it as a long day from Porto, but staying a night is better.

The Algarve. Lagos and the cliffs west of it are the postcard. Tavira in the east is calmer and more Portuguese. August is packed and expensive. June or September is the same coast for half the aggravation.

Evora. A walled town in the Alentejo with a Roman temple standing in the middle of it and a chapel lined with human bones. That last one is either the highlight of the trip for your ten year old or a hard no. You know your kid.

Coimbra. The old university on the hill and one of the most beautiful libraries in Europe. A good stop if you are driving between Lisbon and Porto. Not worth a special trip on its own.

Madeira. Two hours out in the Atlantic. Levada walks along old irrigation channels, cliffs, a proper mountain interior, and almost no beaches. Mild all year. Excellent for families who actually hike.

The Azores. Further out and wilder. Green craters, hot springs, and whale watching that is genuinely reliable. Sao Miguel is the entry point. The weather changes hourly and you have to be relaxed about that.

Strollers lose. Cobbles, hills and polished stone. A carrier beats a stroller in Lisbon and Porto every single time.

Kids are welcome everywhere. Restaurants do not have a kids section and do not need one. Half portions, meia dose, are a completely normal thing to order.

Pick your water carefully. If swimming matters, the south facing Algarve coast is warm. The west coast is for surfing in a wetsuit, not for a five year old paddling.

Watch bags on trams and the metro. Lisbon pickpocketing is opportunistic and it works the obvious tourist routes. Nothing violent. Just do not put a phone in a back pocket on the 28.

Dogs are workable. Portugal is reasonably dog friendly on terraces and in parks, and trains take small dogs in carriers. For Poppy this looks like one of the easier countries in Europe.

Heat is the real risk with kids. Not crime, not food, not language. Shade, water, and a hotel with a pool for the middle of the day in summer.

The hills. Everybody knows Lisbon has hills. Nobody expects to be genuinely out of breath on the way to dinner.

The cold ocean. Kids run at the Atlantic in July and come straight back out. Manage that expectation before you get to the sand.

Electronic tolls. The single most common thing that goes wrong on a Portugal road trip. Sort the transponder at the rental desk and forget about it.

The English. It is better than in Spain, France or Italy. Portugal does not dub its television, so people grew up hearing it. This surprises Americans every time.

The scaffolding. Lisbon and Porto have a lot of buildings mid renovation and a lot sitting empty. The photos are all of the finished streets. The real city is patchier, and I think better for it.
