What's on this weekend? Pentecost long weekend special — 23–25 May
Whit Monday gives us a three-day stretch and Belgium goes all in: the country's biggest free street festival takes over Kortrijk, jazz spills onto Brussels' grand squares, and over a hundred Venetian costumes drift through 18th-century water gardens. If you have to pick one long weekend in May to be here, this is probably it.
⚠️ Practical PSA
Monday 25 May is Whit Monday (Pinkstermaandag / Lundi de Pentecôte) — a public holiday across Belgium. Most shops, banks, and public offices are closed, museums often follow Sunday hours, and trains usually run a Sunday/holiday schedule. Engineering works on the rail network: the high-speed line south of Brussels is closed, which diverts OUIGO trains from Brussels to Paris via Nivelles–Maubeuge for the whole weekend (longer journeys, no stop in Mons). Domestic line works also affect Tienen–Landen and a few other stretches — check belgiantrain.be before you travel. Expect long-weekend crowds at the coast, Bruges, and the Ardennes.
⭐ Weekend highlight: Sinksen — Kortrijk (Fri–Mon)
Sinksen 2026 is Kortrijk's annual four-day Pentecost takeover and one of the largest free city festivals in Belgium. The theme this year is "Back to the future," and the entire inner city becomes one big open-air programme: street theatre and circus acts, live music on a dozen squares, a children's village in Begijnhofpark with workshops and play zones, food stalls along the Broel quays, and a skate bowl with drum & bass and reggae sets. There's no entry fee anywhere.
The single biggest reason to come: on Sunday 24 and Monday 25 May, Kortrijk hosts Flanders' largest flea market — 25 streets and around 4.3 km of stalls weaving through the city centre. Show up early, bring cash for some sellers, and pack a tote.
Practical info: Fri 22 → Mon 25 May. Free. Full programme and city map at sinksen.be. Kortrijk station is a 10-minute walk from the Grote Markt; direct IC trains from Brussels (~1h10), Ghent (~30 min), and Antwerp (~1h30).
🏛️ Brussels
- Lotto Brussels Jazz Weekend (Grote Markt, Place Sainte-Catherine, Place de la Bourse — Fri 22 to Sun 24): Belgium's largest free jazz festival turns three of the city's most iconic squares into open-air stages, with cafés and bars all over the centre programming extra live music. Strong focus on Belgian talent (Orson Claeys, Flat Earth Society, Manou Gallo, Glass Museum) and the Brussels Jazz Vanguard new-talent stage on Sainte-Catherine. Free, no booking. Full lineup and times on the programme page
- City Sunday on 24 May: every last Sunday of the month, the Brussels Pentagon goes car-free from 10:00 to 18:00 — perfect for combining jazz hopping with a long walk.

Free entry; cashless wristband at the gate. Five minutes by tram from Liège-Guillemins (Petit Paradis stop)
🌸 Nature tip
May is peak time for Het Zwin Nature Park on the coast near Knokke — spring migration is winding down but spoonbills, avocets, and storks are nesting visibly from the hides. Combine it with the Bruges → Damme bike ride from our Bruges guide for a low-key counterweight to the festival crowds.
