The São João Festival in Porto is one of the city’s most beloved and lively celebrations. While it is famous for its energetic late-night activities, it offers a great experience for families, especially earlier in the day. We’ve seen some expat friends attend and love going with their kids! One of the landmarks of the festival is the plastic hammers you buy and “bonk” people on the head with. What kid wouldn’t love that?!

The Story Behind the São João Festival

The São João Festival in Porto is a lively festival with deep roots, mixing ancient pagan rituals with Christian traditions. 

Its origins date back to pagan summer solstice events around June 21, when communities celebrated nature, fertility and the sun’s power. Fire was central to these early rituals, symbolizing purification and good fortune. This tradition continues today with bonfires and the release of glowing paper lanterns. 

As Christianity spread, these midsummer celebrations began to honor Saint John the Baptist, whose birth is celebrated on June 24. Linking to water and spiritual renewal, Saint John became the festival’s central figure, blending naturally with the existing solstice customs. 

Traitionally Portugal was and still is, in some ways, a deeply Catholic nation (it was mandatory until the 1970s!) and still honors many saints in their festivities. Most public holidays are related to a saint or a religious event/day.

In Porto, the festival has been recorded since at least the 14th century. Over the years, it transformed from a religious observance into the festive street party we know today, filled with music, fireworks, grilled sardines and playful traditions. Some customs, like the fun plastic hammers used to gently tap fellow party-goers, are more recent, introduced in the 1960s. Yet they’ve become just as iconic, showing how São João keeps growing while remaining true to its joyful, communal spirit.

Where Does All the São João Magic Happen in Porto?

The São João Festival is a city-wide celebration that truly takes over Porto, but the heart of the festivities beats strongest in the Ribeira District. This historic riverside area buzzes with street parties, live music, traditional food stalls and crowds gathering for the iconic midnight fireworks over the Douro River.

Note: This isn’t the best part of town, so visit early if going with kids and keep them close. Pickpockets can be prevalent.

Avenida dos Aliados is another major hub, hosting vibrant parades and large-scale concerts that draw both locals and visitors. For the best view of the fireworks, head to the banks of the Douro or find a spot on the Dom Luís I Bridge. For a more relaxed perspective, cross over to Vila Nova de Gaia, where you’ll still get a spectacular view with slightly thinner crowds.

Beyond the main action, traditional neighborhoods like Miragaia and Fontainhas host intimate community celebrations with bonfires, music and a cozy, local vibe. Throughout Porto, many public squares feature free concerts and lively street scenes well into the night.

In short, São João spills into every corner of Porto, but the historic center and riverside areas are where the energy reaches its unforgettable peak.

What to Expect in São João Festival Porto with Kids: A Feast for the Senses

São João in Porto is a joyful, chaotic and unforgettable celebration, a true feast for the senses that families and children won’t forget anytime soon. But be warned: it’s not for the faint of heart! If you’re looking for calm, this is not the place for you; however it is something worth experiencing at least once in a lifetime.

We just attended the Marches Populares, another June festival in Lisbon, and it was spectacular. However, there were also thousands of people crammed together on a busy street. Festivals are not for the faint of heart! Thankfully, most are family affairs and the Portuguese love kids!

Bops on the Head (Yes, Really)

One of the most playful and iconic traditions of São João features strangers lightly tapping each other on the head with squeaky plastic hammers, a modern twist on the older custom of waving a leek.

What’s the Meaning Behind Tapping Each Other on the Head with Plastic Hammers at the São João Festival?

Tapping heads with plastic hammers is, above all, a playful gesture of good luck, rooted in the idea of warding off the evil eye and inviting positive energy. 

Beyond its symbolic meaning, it creates a sense of camaraderie and shared joy, encouraging spontaneous, lighthearted interactions among strangers and friends. This simple act helps shape the festive, inclusive spirit that defines the São João street celebrations.

Roots and Evolution of This Tradition

This lively tradition has its origins in ancient pagan rituals celebrating the summer solstice, when people would wave wild leeks or garlic flowers believed to offer protection. In the 1960s or 70s, a local factory in Porto introduced the plastic hammer, which quickly caught on. Its playful design and amusing squeaky sound made it a fun, practical alternative to the traditional plants.

In essence, it’s a vibrant mix of age-old protective customs and modern festive flair, one of the many things that makes São João a unique celebration.

Picture your child’s giggles (and maybe a touch of playful mischief!) as they bop strangers on the head with colorful plastic hammers, a beloved São João tradition said to bring good luck. It’s harmless, hilarious and the perfect way to break the ice in Porto’s festive streets.

Where to Buy a Plastic Hammer During the São João Festival in Porto (Especially with Kids)

During the São João festival in Porto, squeaky plastic hammers are sold everywhere by street vendors, making them a fun and iconic part of the celebration. There’s no need to bring your own, as they’re easy to find on the streets and perfect for joining in the festivities.

Kids love the hammer-tapping tradition, so to keep it fun and safe, it’s best to get them a small, soft plastic hammer. It allows them to fully join in the festivities while keeping the experience playful and worry-free.

A Sky Full of Light: Lanterns Released in Porto

As night falls, thousands of balões de São João, small paper hot air balloons, are released into the sky. As night falls, the sky fills with hundreds of glowing paper hot air balloons, drifting upward like a constellation in motion. It’s a magical sight, mesmerizing for kids and heartwarming for grown-ups.

If you want to buy one of these beautiful lanterns, known locally as balões de São João, you’re in luck! They’re widely available from street vendors all over Porto during the festival, especially in the most vibrant celebration areas. There’s no need to bring one with you, just pick one up when you arrive and join in the magic.

And while it’s not a tradition to write wishes on the lanterns, as is done in some other cultures, the act of releasing them is deeply symbolic. Many see it as a way to send their hopes and dreams soaring into the night sky.

When and Where to Launch Your Lantern

As evening falls on June 23rd, the first lanterns begin to rise. The sky slowly fills with glowing orbs leading up to the midnight fireworks, creating a breathtaking scene.

There’s no single launch location, people release lanterns from open spaces all around the city. Popular spots include the Ribeira district, the banks of the Douro River and plazas in the heart of the celebrating neighborhoods. Watching hundreds of lanterns float up against the backdrop of Porto’s skyline and the iconic D. Luís I Bridge is truly unforgettable.

Releasing a lantern is a moment of connection to São João’s ancient roots, symbolizing light, hope and celebration. It’s an experience you won’t want to miss.

Music, Dancing and Ear-Popping in Porto

From lively folk tunes to catchy pop hits, music fills every corner of the city during São João, setting the rhythm for a night of celebration. The beat is irresistible, don’t be surprised if your kids kick off their own little dance party right on the sidewalk! Joy is truly contagious here.

As the night unfolds, traditional melodies echo through the streets, spontaneous dance circles for and the crowds grow with the energy. While some areas can get quite loud and lively, you’ll also find quieter pockets where families can soak up the atmosphere at their own pace, no rush, just pure festive fun.

Decorations with Heart at the São João Festival Porto with Kids

Porto transforms into a festive wonderland for São João, draped in vibrant streamers, glowing light and the signature manjericos, which are potted basil plants adorned with witty or romantic poems. These playful decorations not only light up the city with color and charm but also make for lovely, meaningful souvenirs to take home.

Fireworks Over the Douro

When the clock strikes midnight on June 23rd, prepare to be amazed. Fireworks burst over the Douro River in a dazzling display that lights up the entire city. It’s the perfect grand finale, but be ready for big crowds and loud booms (a good moment to have ear protection on hand for little ones).

What To Eat During São João Festival

Eating during São João is all about immersing yourself in the street food culture, though traditional restaurants are available if you’re looking for a sit-down option. We love the food in Portugal (clearly, we live here!), and encourage you to try the traditional items even if they sound a bit weird!

From smoky grills to sweet treats, the festival turns Porto into an open-air food lover’s paradise.

Festival Food Favorites

• Grilled Sardines: The star of the show, served with crusty bread and often grilled peppers. The juices of the sardine are meant to soak into the bread. It sounds weird, but it can be really good. You’ll need to pick out the bones, but the smoky meat is tasty!  It’s also a bit of a comfort food for the Portuguese. 🙂

• Bifanas: Spicy, garlicky pork sandwiches that make a satisfying street snack. The bread is key here being crusty on the outside and soft in the middle. A classic treat in street fairs!
  
• Caldo Verde: A warm, comforting green soup made of Galician cabbage, potatoes, onion, garlic, chorizo, and olive oil. If you are a bit chilly or looking for something on the healthy side, this is a great option.
  
• Farturas: Sugar-dusted fried dough, similar to churros, a must for dessert lovers. These are our FAVORITE dessert in Portugal, even more than the beloved pastel de nata. We love these babies. Think cinnamon sugar donut has a baby with a churro. These are amazing. They are cooked in big spirals (like a snake) and cut into pieces. When we have all our five kids, we go for a dozen! Teenage boys love these too. 🙂
  
• Cachorrinhos: Porto’s take on hot dogs, grilled and spicy in a crusty roll. Often these come with ketchup and crispy potato sticks.

Where to Eat During São João Festival

1. Street Stalls & Neighborhood Grills (Highly Recommended)

Found all over the city, especially in Fontainhas and Miragaia, these offer the most authentic experience. Expect lively crowds, communal seating and freshly grilled food. Cash only is common.

2. Casual Restaurants & Tascas

Traditional Portuguese eateries in Downtown (Baixa) and Ribeira often stay open during the festival. They’re great for escaping the crowds while still enjoying festival flavors.

Ribeira has restaurants such as Adega São Nicolau, which offers a warm, welcoming atmosphere. It’s a favorite among locals and visitors alike, often recommended for those seeking an authentic Porto dining experience.

Pro Tip: Due to its popularity and central location, booking a table during the São João Festival can be quite difficult, so early reservations are essential.

Also, Taberna dos Mercadores offers a cozy and authentic traditional Portuguese dining experience, often mentioned alongside its sister restaurant, Adega São Nicolau. It delivers the same high-quality local cuisine in an intimate setting. Like its counterpart, Taberna dos Mercadores is very popular, especially during festival times, so early reservations are highly recommended.

And, in downtown, try places like Café Santiago for a sit-down take on local classics like the Francesinha or bifanas.

3. Food Options for earlier in the day.

• Mercado do Bolhão: Great for local snacks and daytime browsing.

• Time Out Market Porto: A modern option with a variety of cuisines, though expect heavy crowds.  We love the Time Out Market in Lisbon, but it’s always packed!
  
  To make the most of the São João food scene, adopt a “snack and graze” approach. Sampling a bit of everything from different vendors adds to the fun. Start your food hunt early in the evening to avoid long lines and sold-out favorites, and most importantly, stay flexible. Embrace the lively, slightly chaotic atmosphere, it’s all part of the festival magic.

Premium Hotels for the São João Festival in Porto

First we have the Yeatman Hotel, which offers a luxurious escape with breathtaking panoramic views of Porto and the Douro River, making it one of the best places to watch the São João fireworks.

Another comfortable option is InterContinental Porto – Palácio das Cardosas, this hotel places you right in the heart of the action. It offers valet parking and access to a nearby public garage, but during the festival, walking is the best (and often only) way to get around during São João, and this hotel puts you right where you need to be.

Nightly rates during peak times like during the São João Festival, the rates range from € 350 to  € 600+ for standard rooms. For premium accommodations, prices can climb to €700 to €1500+ per night, especially during peak times like the São João Festival. 

Standard Hotels for the São João Festival in Porto

Hotel Spot Family Suites is a fantastic base for families. It offers spacious suites with kitchenettes, ideal for quick meals and snack breaks. While not directly on Avenida dos Aliados, it’s within easy walking distance of key festival zones. 

The hotel doesn’t have private parking, but it’s located close to public underground garages like Silo Auto, the average pricing starts at €12 per unit. Average price ranges between €140 and €175+ per night for a standard room or family suite, depending on availability, room type, and the season.

The other option is Mercure Porto Centro Aliados, just steps from Avenida dos Aliados. Rooms are sleek and comfortable, and the hotel often provides private parking, a rare perk in the historic core.

Budget-Friendly Hotels for the São João Festival in Porto

If you’re looking to enjoy the São João festivities without breaking the bank, Hotel ibis Porto São João and Moov Hotel Porto Centro offer solid value, each with different advantages depending on your priorities.

Hotel ibis Porto São João is about 3-4 km from the city center, so it’s not walkable to the main festival zones. However, it offers a major perk: free on-site private parking, a rarity during festival time. It’s also just a two-minute walk to the I.P.O. Metro Station, where a 10-minute metro ride takes you directly into the heart of the city. 

Average prices range from €70 to €95 per night, but during the São João Festival, prices can rise to €120–€200+, depending on demand and room availability. 

If staying central is your top priority, Moov Hotel Porto Centro is a great budget option with a central location near Praça da Batalha and São Bento Station, ideal for walking to São João festival events. However, it lacks private parking, so it’s best for guests to rely on foot or public transport.

Average prices range from €100 to €180 per night, but due to the hotel’s central location, prices during the São João Festival can increase to an estimated €200 to €350+ per night.

How to Make the Most of São João Festival with Kids

Porto’s São João Festival is a vibrant, family-friendly celebration, brimming with traditions that children will absolutely love. From tapping heads with colorful plastic hammers, a playful local custom, to watching hundreds of glowing paper hot air balloons rise into the night sky, the experience is magical for all ages.

To help you make the most of this unforgettable event, here are our top suggestions:

• To avoid being overwhelmed, start early, around 6 or 7 PM, before the main crowds arrive.  

• Bring ear protection for sensitive ears during the midnight fireworks.  

• Set a meeting point and ensure children carry identification in case they get separated.  

• Keep wipes and hand sanitizer handy for easy cleanup.  

• Wear comfortable shoes for you and the kids; you’ll be doing a lot of walking.  

• Dress in layers so you can adjust as temperatures drop at night.  

• If you’re with little ones, a baby carrier is much more practical than a stroller in the dense crowds.  

Pro Tip: It might sound like a joke, but during São João, finding an open restroom can be a real challenge. Many cafés and bars mysteriously display “out of order” signs throughout the night. Your most reliable option will be public toilets, but expect lengthy queues, especially as the night goes on. If you eat in a restaurant, be SURE to use the bathroom!

 If you’re attending with kids, plan ahead. Those wait times can feel extra long for little ones!

Celebrating São João in Porto with kids is more than just a night out, it’s a deep dive into one of Portugal’s most joyful and culturally rich traditions. From squeaky hammers and glowing paper balloons to mouthwatering street food and dazzling fireworks, the festival delivers unforgettable moments for all ages. With a bit of planning, a good sense of adventure and plenty of snacks on hand, your family can experience the magic without the stress.

Whether you’re watching the fireworks from the Douro River banks, dancing in the streets to folk tunes or simply soaking up the vibrant atmosphere, São João offers a unique and heartwarming way to make memories together. It’s a chaotic, colorful and completely wonderful night, one your kids will talk about long after the last fartura has been eaten.
