King's Day in the Netherlands: What Happens and Where to Go

What King's Day is and why the date can shift

Koningsdag celebrates the birthday of King Willem-Alexander, and the Dutch treat it as a nationwide party rather than a solemn public holiday. It normally falls on 27 April, but when that date lands on a Sunday the celebrations move forward to Saturday the 26th, so the date is worth confirming before you book anything. Because the rule depends on the weekday, a city break built around King's Day needs checking against a calendar rather than a fixed booking assumption.

The date is also useful for planning around the spring season more broadly, since late April sits at the tail end of the bulb fields and the start of warmer city weekends. If you are building a longer trip, it is worth reading about the best time to see tulips alongside King's Day planning so the two fit together.

What actually happens: orange, vrijmarkt and street parties

The most visible custom is orange clothing: on King's Day the Dutch dress head to toe in the national colour, and visitors who join in blend in rather than stand out. Beyond the outfits, the day is built around the vrijmarkt, the free flea market where residents sell second-hand goods on pavements and in parks, alongside live music and street parties in city centres.

King's Night is the informal eve of the holiday, when parties and clubs get the celebrations started before the main day. The day itself is mostly outdoor and centred on the streets, so the sensible plan is to walk rather than schedule museum time, especially as the biggest crowds gather in the centre.

Late April is also when the bulb season is winding down, so if flowers are part of the plan, check the wider spring picture before committing the whole trip to King's Day alone. The tulip fields in the Netherlands guide is a useful comparison for how the two spring highlights overlap.

Where the royal family goes and why that city fills up

The royal family spends King's Day in a single host city each year, arriving for speeches and live music before mingling with residents. In 2024 that city was Emmen, which gives a sense of how the choice rotates around the country rather than staying in Amsterdam.

If you happen to be in the host city, expect far heavier crowds than elsewhere, and plan around the visit rather than trying to compete with it. For most city-break travellers outside that city, the practical effect is simply that the national mood is high and the streets are busy everywhere.

Celebrating in The Hague, Rotterdam and Leiden

DutchReview's 2024 round-up describes The Hague as taking King's Day seriously and beginning the holiday early, Rotterdam as keeping things more personal with flea markets, live music and the occasional party around the centre rather than one giant event, and Leiden as a more toned-down celebration than Amsterdam, with children's flea markets, antique markets, festivals and games for children in the parks and squares.

That difference matters for families: Leiden's park-based games and children's markets suit a calmer day with younger travellers, while The Hague and Rotterdam lean more towards music and city-centre crowds. If you are planning around the spring calendar more broadly, the Netherlands in April guide covers what else is happening in the same weeks.

Why Amsterdam draws the biggest crowds and what it means

Amsterdam draws the biggest King's Day crowds, with much of the city centre blocked off and limited public transport and car travel allowed inside. The festivities start on King's Night and roll into a full day of parties, flea markets and live music, with the streets extremely crowded.

For a city break based elsewhere, Amsterdam is best treated as a transport hub on this day, since the crowds and closures make it a poor base if you want to move around easily. If your trip starts there, plan to leave the city rather than fight it. If your spring trip is built around flowers rather than the party, the Netherlands in spring guide covers the season's other highlights.

Getting around when streets close and transport is limited

On King's Day, city centres fill with people and streets are closed to traffic, and in Amsterdam the city centre is largely blocked off with limited public transport and car travel allowed inside. The practical approach is to arrive early, pick a base within walking distance of the centre, and walk between squares rather than trying to drive in.

Because the day is outdoors and largely spent wandering, walking is the sensible way to get around. If you are combining King's Day with a flower visit, Keukenhof is a different kind of spring day out and sits outside the biggest celebrations.

If you want to see the bulb fields around King's Day, the guide to visiting Keukenhof without making Amsterdam your base explains the options. The Keukenhof tickets information is worth reading before you set a date, since the gardens sit outside the King's Day crowds.

A realistic plan for one King's Day outside Amsterdam

Pick one city and stay put: arrive the evening before, experience King's Night if you want the atmosphere, then spend the main day walking the vrijmarkt and squares rather than booking museums. Leiden suits a family day, The Hague suits a full programme of events, and Rotterdam suits a lower-key wander.

Wear orange and treat food and drink as part of the street scene rather than a planned restaurant stop. If the party is only one part of your trip, the Netherlands in May guide covers what follows in the weeks after King's Day.

For a spring trip that combines King's Day with flowers, Keukenhof is the obvious name, and the wider tulip festival Netherlands calendar helps place both in the same fortnight. If tulips around Haarlem appeal, the Haarlem tulip fields guide covers those fields, while the tulip fields near Rotterdam guide is useful if you base yourself there.

Which city should you pick for King's Day?

Choose Leiden for a calmer, family-friendly day with park games and children's markets, The Hague for a fuller programme of events, and Rotterdam for a relaxed wander with markets and music. Amsterdam is the biggest party but also the most congested, so treat it as a transport hub if you are staying outside the capital.

Whatever city you choose, the day is outdoors and crowded, so wear orange, arrive early, and plan to walk. If your trip extends beyond the holiday, the tulip fields in the Netherlands guide covers the spring season around it.
