Top Things to Do and See in Portugal

Portugal's highlights are spread along a compact coastline, so you can combine palaces, wine country, medieval towns and dramatic cliffs in a single trip. Here are the sights and experiences most worth your time, grouped by area, with tips on when to book.

Lisbon

• Alfama and São Jorge Castle: the oldest quarter's tangle of lanes, laundry lines and tiny squares leads up to castle walls with sweeping views over the river and rooftops.
• Tram 28: the vintage yellow tram rattles through Graça, Alfama and Baixa. Ride early in the morning, before the queues build, and keep your belongings close.
• Belém: the Manueline stonework of the Jerónimos Monastery, the riverside Belém Tower and the Monument to the Discoveries tell the story of Portugal's age of exploration. Finish with a warm custard tart from one of the local bakeries.

Sintra and the Atlantic coast

Sintra deserves a full day. Pena Palace is a riot of colour on a hilltop, while Quinta da Regaleira hides grottoes, tunnels and a spiralling initiation well in its gardens. The ruined Moorish Castle offers some of the best views in the area.

From Sintra, it's a short drive or bus ride to Cabo da Roca, the westernmost point of mainland Europe, where wind-blown cliffs drop into the Atlantic. Many people continue to Cascais for a seaside evening and catch the train back to Lisbon.

Porto and the Douro Valley

• Ribeira and the Dom Luís I Bridge: walk the waterfront, then cross the bridge's upper deck for the classic view of the city stacked above the river.
• Port lodges in Vila Nova de Gaia: cellar tours and tastings explain how port is aged and blended.
• Clérigos Tower: climb the narrow staircase for a panorama of terracotta roofs.
• The Douro Valley: terraced vineyards line the river east of Porto. Take the scenic train along the Douro line from São Bento, join a river cruise or visit wine estates around Pinhão.

Central Portugal

Coimbra University sits on a hilltop overlooking the city, and its baroque Joanina Library is one of the most beautiful rooms in the country. Further west, Óbidos is a walled medieval town where you can walk along the ramparts (there are no railings, so watch your step) and sip ginja from a chocolate cup. In winter, head to Nazaré, where some of the biggest surfed waves in the world break off Praia do Norte; the lighthouse fort is the place to watch.

The Algarve

• Ponta da Piedade, Lagos: golden sea stacks, arches and grottoes best seen from a small boat or kayak.
• Benagil sea cave: the famous cavern with a hole in its roof is visited on boat and kayak trips from nearby towns. Access rules and sea conditions change, so check what is currently allowed and book with a licensed operator.
• Seven Hanging Valleys Trail: a clifftop walk between Praia da Marinha and Vale Centeanes with superb coastal views.
• Ria Formosa: a protected lagoon of sandbanks and islands, reached by boat from Faro and Olhão.

Booking tips

• Book timed tickets for Pena Palace and Quinta da Regaleira online in spring and summer, and aim for the first slots of the day.
• The Jerónimos Monastery draws long queues; go early or book ahead.
• Many national museums and monuments close on Mondays, so check before planning your day.
• Entry to Coimbra's Joanina Library is by timed slot, which can sell out in busy periods.
• Book Douro tours and Algarve boat trips a day or two ahead in peak season, and remember that rough seas can cancel boat departures.
• City cards in Lisbon and Porto combine public transport with reduced entry to many sights, and can be worth it if you plan a busy few days.
