Planning a trip to Portugal’s capital? Whether you’re visiting for a day on a cruise ship or spending a weekend, Lisbon is full of charm, color, and seriously good food. Here are my top 5 must-do activities in Lisbon – a mix of iconic sights, local flavors, and experiences that will totally win you over, especially when you only have a limited amount of time.

1. Eat ALL the Pastel de Nata at Pastéis de Belém

First things first – you haven’t really been to Lisbon until you’ve eaten a pastel de nata. And the best place to try one (or ten) is the legendary Pastéis de Belém.

These flaky, creamy Portuguese custard tarts are famous for a reason. Warm, caramelized tops, buttery layers… I still dream about them. Learn from my mistake: don’t just order one. Go big. Get a box. You’ll thank me later.

Pro tip: Pair your tart with a strong bica (Portuguese espresso) and enjoy it at one of the bakery’s historic tiled tables.

2. Explore the Beauty of Belém Tower

After fueling up on pastries, head down the river to the stunning Belém Tower (Torre de Belém) – a 16th-century fortress that’s one of Lisbon’s most iconic landmarks.

This UNESCO World Heritage Site once protected the city’s harbor and now offers gorgeous views over the Tagus River. It’s like stepping straight into a history book, with a castle-meets-seaside vibe that’s totally unique to Lisbon.

Don’t miss: Taking a few photos from the riverside promenade – it’s a picture-perfect spot.

3. Marvel at Jerónimos Monastery

Just a short walk from the tower is another can’t-miss spot: Jerónimos Monastery. This jaw-dropping building is a masterpiece of Manueline architecture and home to the tomb of explorer Vasco da Gama.

Wander through the peaceful cloisters, admire the intricate stonework, and soak up the feeling that you’re walking through centuries of history.

Insider tip: The cloisters are quieter early in the day and absolutely stunning for photos.

4. Ride the Iconic Tram 28

For a true Lisbon experience, hop aboard the famous yellow Tram 28. This vintage tram winds its way through some of the city’s most historic neighborhoods – including Alfama, Graça, and Baixa – giving you a scenic tour of Lisbon’s hills, tiled buildings, and tight alleyways.

Pro tip: Go early or late to avoid crowds. Or grab a seat at a less busy stop away from the main tourist areas. And at the top of the route, stop for lunch with panoramic views over the red-tiled rooftops. Honestly, it’s a vibe.

5. Stroll Through Praça do Rossio (King Pedro IV Square)

Last but not least, take a moment to chill in Praça do Rossio, also known as King Pedro IV Square. This lively square in central Lisbon is perfect for people-watching, grabbing a coffee, or just soaking in the atmosphere.

You’ll spot gorgeous wave-patterned cobblestones, 18th-century buildings, the majestic National Theatre, and the tall statue of King Pedro IV keeping watch from the center.

It’s a great place to pause and take in the energy of Lisbon – locals chatting, street performers doing their thing, and visitors from all over the world.

Wear comfy shoes — Lisbon is hilly, and cobblestones are no joke.
Use public transport — Trams and the metro make getting around easy.
Stay hydrated — Especially in the summer sun.

How to Get Around Portugal
Getting around Portugal is part of the adventure and thankfully, it’s incredibly well set up for travelers.

Trains are hands-down the best way to travel between major cities (check out Rail Europe for tickets and trip planning), while Booking a rental car give you the freedom to explore the countryside, coastal roads, and tiny villages at your own pace.

Portugal SIM Card: Airalo eSIM
Staying connected in Portugal is a must for maps, transport apps, bookings, and Googling “best pastel de nata near me” (trust me). I used Airalo, an eSIM app that lets you download a data plan before you even land.

There’s no need to swap physical SIM cards or hunt down a store at the airport. Just activate your eSIM and you’re online the moment you arrive – easy, affordable, and super convenient.
