Halloween in Porto in 2026 offers more than costume parties and late-night events. 

On 31 October, you can carve a pumpkin at one of the city’s best-known markets, solve a mystery inside a museum, explore a historic church after dark or cross the Douro for an afternoon and evening of music. 

If you are spending Halloween in Porto this year, these are some of the plans to consider from morning until late at night. 

Start with a Jack-o’-Lantern at Mercado do Bolhão 

31 October | 11:00 AM–1:00 PM| Mercado do Bolhão 

Halloween starts early at Bolhão this year. 

As part of its regular Sábados em Família programme, Mercado do Bolhão hosts a Jack-o’-Lantern workshop on 31 October. 

Children and families can design and carve their own pumpkins with support from the PAZ – Performance Arts Zone team, before taking their creations home. 

The activity is suitable for children aged five and over when accompanied by an adult. Participation is free, subject to capacity. 

It is an easy way to add Halloween to a morning in the city centre while also visiting one of Porto’s most recognisable markets. 

From Almada234, Bolhão is close enough to combine with breakfast, a walk through Baixa and the rest of your plans for the day. 

Solve a Halloween mystery at the Tram Museum 

31 October | 3:00 PM and 5:00 PM | Museu do Carro Eléctrico 

Later in the day, the atmosphere becomes more mysterious. 

For A Última Viagem – The Last Trip, the Tram Museum becomes the setting for an interactive crime investigation. 

Families follow a route through the museum, meet different characters, listen to testimonies, complete challenges and collect clues to discover what happened and identify the culprit. 

Sessions take place at 3:00 PM and 5:00 PM, making this a good option for families looking for something more interactive than a conventional museum visit. 

The setting also adds a distinctly Porto element to the experience, with the city’s historic trams providing the backdrop. 

See Trindade differently after dark 

31 October | 6:30 PM and 10:00 PM | Experience Trindade 

Once night falls, one of the evening’s more unusual programmes takes place in the city centre. 

Experience Trindade by Night – Halloween Special opens the Church and the Ordem da Trindade circuit for an after-hours guided visit. 

The two-hour experience includes access to the terraces overlooking the illuminated city centre, accompanied by live music from soprano Daniela Rego and organist Samuel Pinto. 

There are also Halloween elements incorporated into the visit. 

Rather than relying on costumes or traditional scares, the experience uses the building’s architecture, history, music and nighttime atmosphere to create a different kind of Halloween evening. 

Sessions take place at 6:30 PM and 10:00 PM, with tickets listed at €15. 

For guests staying at Almada234, Trindade is nearby, making this one of the easiest evening options to combine with dinner or other plans in the centre. 

Cross the Douro for Halloween with Maz 

31 October | from 4:00 PM | The Baron’s Hall, Vila Nova de Gaia 

If your idea of Halloween involves music rather than mysteries, cross the Douro to Vila Nova de Gaia. 

Bloom & Maz Halloween Porto 2026 takes place at The Baron’s Hall from 4:00 PM, with Brazilian DJ and producer Maz announced as part of the line-up. 

House, deep house and tech house shape an event designed to continue well beyond the afternoon. 

It offers a very different Halloween experience from the family activities taking place earlier in the day – and shows how varied the programme is on 31 October. 

Step into The Secret Factory at The Thriller – Episode II 

31 October | from 11:00 PM | Secret location, Porto 

The Thriller – Episode II: The Secret Factory offers a late-night Halloween experience at a secret location near Porto city centre. 

The location is revealed to ticket holders on 31 October, and the experience begins on the journey there, with actors and themed transport leading to an old factory transformed for Halloween. 

Inside, expect themed rooms, performers, music and a DJ programme. 

The event starts at 11:00 PM. 

Build your own Halloween day in Porto 

You do not necessarily need to choose just one event. Porto’s relatively compact centre makes it possible to combine different plans throughout the day. 

Start with breakfast in Baixa and walk to Bolhão for the morning workshop. Spend the afternoon solving the mystery at the Tram Museum, return to the centre for dinner and then choose between the night-time experience at Trindade or an evening of music in Gaia. 

Or keep part of the evening free simply to experience Porto after dark. 

Areas such as Clérigos, Galerias de Paris, Ribeira and Baixa take on a different atmosphere at night, and on 31 October you are likely to see a few more costumes than usual. 

Why staying in the centre helps on Halloween 

Halloween is one of those days when a central location can make plans easier. Activities can stretch from morning until late at night, and you may want to return to your apartment before dinner or before heading out again. 

Almada234, on Rua do Almada, places you in the heart of downtown Porto, close to Aliados and within easy reach of Bolhão and Trindade. 

For destinations further away, public transport makes it straightforward to reach other parts of Porto or cross towards Vila Nova de Gaia. 

That flexibility allows you to explore during the day, take a break and head out again once the city moves from autumn afternoon into Halloween night.
