Start your trip by visiting the historic Belém district. This riverside area is home to some of Lisbon's most famous landmarks, including the tower of Belém and the Jerónimos Monastery, a UNESCO World Heritage Site. You can also taste the famous Pastéis de Belém at the bakery of the same name, which has been making this delicious custard tart recipe since 1837.
Get lost in the maze of streets of the Alfama neighborhood, one of the oldest in Lisbon. Wander through picturesque alleys before heading uphill to the Castle of São Jorge, which dates back to the 11th century. From its ramparts, you'll enjoy sweeping views of the city and the Tagus River.
On your final day, explore the elegant neighborhoods of Chiado and Baixa. Shop for luxury brands and local souvenirs on the bustling streets, then take a break at one of the many cafes or bakeries. Don't miss the opportunity to ride on the famous Tram 28, which links the city's historic neighborhoods.
If you have more time, consider taking a day trip to Sintra to see the fairytale-like Pena Palace and the Castle of the Moors. Foodies may also want to take a guided tasting tour of Lisbon's many culinary delights. Those with less time can skip the Alfama Neighborhood or the Castle of São Jorge and spend more time in the other areas.
