The honest difficulty with a two-week Iberian trip is not finding things to see, it is the border. Every version of this route I have seen online either wastes two days on backtracking or pretends that a train from Lisbon to Seville is a simple hop, when in practice it means a change in Entroncamento or a bus that takes six hours. The route below is built around the transfers first and the sights second, and it runs from Barcelona to Lisbon in fourteen nights with no leg longer than four hours.
I have driven it, taken the trains and once did the whole Lisbon-Seville stretch by bus to see what it cost. What follows is the version with the best balance of time on the ground and time in transit, with the fares I paid last season as a reference.
The skeleton: seven stops, fourteen nights
- Barcelona, 2 nights. Arrive, recover, walk the old town.
- Madrid, 2 nights. Museum day, then the train south.
- Seville, 3 nights. The longest stay; day trip to Cordoba from here.
- Granada, 2 nights. Alhambra booked before you leave home.
- Málaga, 1 night. Coast, Picasso museum, easy airport for the hop west.
- Lisbon, 3 nights. Day trips to Sintra and Cascais.
- Porto, 1 night, then fly out or continue north.
That is 14 nights with two flight days counted as travel. If you insist on ending in Porto, fly Lisbon-Porto rather than taking the train when you are short on time; the domestic fare sits around 40 euros booked a fortnight ahead, against four hours on the Alfa Pendular.
The legs, with real times
Barcelona to Madrid is the cleanest leg in Spain: the AVE covers the distance in two and a half hours, with departures every half hour from Sants. Madrid to Seville is two and a half hours on the AVE; Madrid to Cordoba is an hour and forty minutes. Seville to Granada has no fast train, so the choices are the ALSA bus (three hours) or a train with a change (four and a half); I take the bus unless I am travelling with luggage I refuse to lift.
Granada to Malaga is a two-hour bus or a one-hour train that does not exist yet, so bus it is. Malaga to Lisbon is the break in the pattern: a direct train has not returned, so fly (an hour, 50 to 90 euros) or take the bus via Huelva (six hours, cheaper but it eats a day). Within Portugal, Lisbon to Porto is two hours fifty on the Alfa Pendular if you book it, four hours on the regional.
What to book before you leave
Three things sell out and everything else can wait. The Alhambra Nasrid Palaces ticket goes weeks ahead in spring and autumn; the Sagrada Familia sells out for specific time slots about ten days out; and the first overnight in each city is worth locking in, because arriving late and finding nothing is what turns this route sour.
Fares are worth a weekly check rather than a daily one. Spain rewards early AVE purchases at 30 to 60 days out, Portugal rewards Renfe/CP bookings at two to three weeks, and buses barely move in price at all, so buy those when you know your date and no earlier.
Where the two countries meet
The border crossing is the part people get wrong. Trains between Spain and Portugal are limited and mostly require a change, so most travellers fly or take the bus. The coach from Seville to Lisbon runs overnight in summer and takes about six hours; the daytime bus via Huelva and Faro is seven hours but arrives at a useful hour and costs a third of a flight.
If you are driving instead, note that the hire car picked up in Spain is usually not allowed into Portugal without a cross-border fee, and the opposite direction costs more. The A6 motorway between Badajoz and Lisbon is fast and cheap, with tolls around 25 euros.
Money, food and the rhythm of the day
Spain eats late and Portugal eats earlier, and the transition is the one cultural adjustment this route asks for. In Andalusia, lunch runs from two and dinner never starts before nine; in Lisbon, a proper lunch is at one and the kitchens are quiet by ten-thirty. Build your days around that: big meal in the middle, light evening, and never book a guided tour for eight in the morning after a nine-thirty dinner.
Budget roughly 60 euros a day per person for food if you eat well but not expensively: coffee and a pastry for breakfast, a menu del dia for lunch in Spain at 12 to 15 euros, and a counter meal with wine in Portugal at 20 to 25. Museums and transport add another 20 to 30 on days when you use them.
What I would cut first
If fourteen nights become ten, drop Barcelona and start in Madrid; it costs you one flight connection and saves a full day of transit. If they become eighteen, add the Algarve between Seville and Lisbon instead of Málaga, and give Porto two nights rather than one. The route survives both changes because its logic is the transport spine, not any single city on it.
Two things people get wrong
The first is treating the trip as two separate holidays joined at the border, which leads to a rest day in each country that the fortnight cannot afford. Move through, arrive in the afternoon and walk the old town before dinner; you will have seen more of Lisbon that way than by sleeping late. The second mistake is booking everything before departure, including the buses. Trains reward it, buses do not, and holding a non-refundable seat on a leg you end up changing costs more than the fare you saved.
