King’s Day in Amsterdam (Koningsdag) is the wildest, most colourful day in the Dutch calendar — when 1 million people in orange flood the city’s streets, canals, and parks to celebrate the king’s birthday with boat parties, flea markets, live music, and street food. King’s Day 2027 falls on Tuesday, 27 April 2027. This guide covers the date, history, what to wear, the best canal-party and vrijmarkt spots, transport tips, and everything first-timers need to survive (and enjoy) Amsterdam’s biggest party.

What is King’s Day?

King’s Day (Koningsdag) is the Netherlands’ national holiday celebrating the birthday of King Willem-Alexander, who was crowned in 2013. The holiday has existed in some form since 1885, when it was Queen’s Day for Queen Wilhelmina’s birthday. Until 2013 it was Queen’s Day (Koninginnedag) and celebrated on 30 April for the late Queen Juliana’s birthday. With Willem-Alexander’s accession, the date moved to his actual birthday: 27 April.

The defining feature is the colour orange — a nod to the House of Orange-Nassau, the Dutch royal family descended from William of Orange, founding father of the Dutch state. On King’s Day every Dutch person wears orange, and the country becomes one giant party. Amsterdam, with its canals, narrow streets, and dense population, is the most intense place to experience it.

What to Wear

Orange. As much as possible. The unwritten rule is: if you’re not wearing orange, you’ll feel out of place. There are no real limits — Dutch creativity goes wild. Some standard outfit ideas:

• Orange T-shirt or jersey (the cheap-and-easy route — H&M and HEMA stock plenty in April).
• Dutch national football shirt (Oranje) — works any year.
• Orange wig, feather boa, glasses, hat, face paint — the louder the better.
• Orange tutu / inflatable crown / oversized sunglasses for the full Koningsdag experience.
• Practical layers: April weather in Amsterdam is unpredictable. Sun, rain, and 12°C all in one day is normal.
• Comfortable shoes you don’t mind getting trashed — you’ll walk 15-20km and spill drinks on yourself.

Tip: Buy your orange gear before the day. Costume shops and supermarkets sell out by King’s Night, and prices spike. Bring something from home or shop the week before.

Best Spots to Celebrate King’s Day in Amsterdam

The Jordaan

The most atmospheric Amsterdam neighbourhood for Koningsdag. Narrow streets (Westerstraat, Lindengracht, Elandsgracht), brown cafés overflowing onto the pavement, live music on outdoor stages, and the city’s most beloved vrijmarkt. Locals come here. Pace yourself: crowds are dense, queues at bridges are slow, and you’ll want to stop every 20 metres for another drink and another singalong. See our Jordaan neighbourhood guide for the full picture of the area.

Vondelpark

The famous children’s vrijmarkt. Only kids are officially allowed to sell — they bring out their old toys, books, drawings, homemade cookies, and stage tiny musical performances for tips. The atmosphere is sweet, less drunken, family-friendly. Adults park themselves on the grass, drink cans of Heineken, and listen to kids singing pop songs through tiny portable amps. The perfect King’s Day spot if you’re travelling with children, or just want a calmer vibe.

The Canals (Prinsengracht, Keizersgracht, Herengracht)

The canal party is the most iconic image of Koningsdag: thousands of boats, all blasting different music, packed gunwale to gunwale, weaving through the historic centre. If you don’t have a boat (and a captain who can navigate the chaos), you can watch from any bridge. The bridges at Prinsengracht/Brouwersgracht, Reguliersgracht/Herengracht, and the Magere Brug are the most photogenic vantage points. Want to be on a boat? Book a public King’s Day cruise weeks in advance — see "Boat Parties" below.

Museumplein

The big open-air concert venue. Massive stages, headliner DJs, tens of thousands of people, free entry. Most international visitors gravitate here because it’s open and easy. Locals tend to find it too commercial, but if you want festival energy without paying, Museumplein delivers. Crowds peak from 2-6pm.

Apollolaan & Beethovenstraat (Zuid)

The best vintage vrijmarkt. Wealthier neighbourhood, so the cast-off goods are higher quality — designer clothes, vintage furniture, books, art. Quieter crowds, more relaxed. Combine with Vondelpark (20-minute walk).

Westerpark / NDSM

For the techno crowd. Big day parties at Westergasfabriek (Westerpark) and across the IJ at NDSM-Werf. Ticketed events with international DJ line-ups — buy in advance, often months ahead. Hipper, younger, more party-festival than street party.

The Vrijmarkt: Amsterdam’s Giant Flea Market

One of the unique features of King’s Day is the vrijmarkt ("free market") — the one day a year when anyone in the Netherlands can sell their used goods on the public street without a permit or tax. The result: a city-wide flea market with everything from designer vintage clothes to childhood toys, vinyl records, art, kitchenware, ice creams, and homemade waffles. It’s part bargain hunt, part urban garage sale, part performance art.

Best Vrijmarkt Areas

• Jordaan (Westerstraat, Lindengracht, Noordermarkt) — best overall mix of bargains and atmosphere.
• Vondelpark — children-only vendors; perfect for families.
• Apollolaan / Beethovenstraat / Cornelis Schuytstraat — best vintage / designer pickings.
• De Pijp (Sarphatipark, Albert Cuyp area) — small-scale, neighbourhood feel.
• Oud-West (Bilderdijkstraat side streets) — relaxed, less touristy.

Vrijmarkt Tips

• Arrive early: vrijmarkt starts at sunrise (legally 06:00). 06:00-08:00 is when the best stock is on offer.
• Come back late: from 16:00, sellers want to go home and will dump prices.
• Bring cash: small bills (€5, €10). Many sellers don’t take cards.
• Haggle politely: prices are starting points; halving is normal at the end of the day.
• Bring a sturdy bag for the finds you didn’t plan to make.

Boat Parties & Canal Cruises

If you can get on a boat on King’s Day, do it. The canals are the heart of the celebration. There are three ways onto the water:

1. Public Koningsdag Cruises

Operators like Lovers, Stromma, and smaller charter companies run dedicated King’s Day cruises. Open-top boats, DJ, music, drinks included, 2-4 hours. Book 4-8 weeks in advance — they sell out fast. Expect to pay €60-120 per person depending on operator and inclusions.

2. Private Boat Charter

Rent a private boat with a skipper for your group. Costs €600-1500+ depending on size and operator. Book 2-3 months ahead; popular sloops sell out by January for the next year. Bring your own drinks and snacks. The captain handles navigation through the chaos.

3. Friend’s Boat

If you know someone who owns a sloop or canal boat: this is your golden ticket. Bring drinks, snacks, a portable speaker, and 6 friends. Pure Koningsdag magic.

Important canal rules on King’s Day: boats must keep moving (no anchoring on the canal), alcohol is allowed on board but not glass bottles, music volume is theoretically capped (rarely enforced), and the police are out in force. Don’t be the boat that capsizes — it happens every year. For more on Amsterdam by water, see our canal cruise guide.

King’s Night (Koningsnacht): The Night Before

Many locals say King’s Night is better than King’s Day. The party kicks off the evening before — Monday 26 April 2027 — with concerts, DJ sets, and bar crawls all over the city. The bars stay open until 5am, clubs run all night, and famous venues like Paradiso, Melkweg, and AIR host huge ticketed parties. The vibe is wilder, younger, and more concentrated than the daytime party.

Hot spots: Leidseplein (bars overflowing onto the streets), Rembrandtplein (mainstream party crowd), the Jordaan (more local, more relaxed), and ticketed events at Paradiso, Melkweg, Westergasfabriek, NDSM-Werf. If you have the stamina, do both nights — but pace yourself, because King’s Day starts at 06:00.

Food & Drink

King’s Day eating is street food: tompouce (a Dutch pastry traditionally iced orange on the day), haring (raw herring with onion), kibbeling (fried fish), oliebollen, stroopwafels, fresh waffles, French fries with mayo, kapsalon. Bars and cafés sell snacks at outdoor stalls. The vrijmarkt itself includes plenty of homemade snacks from local kids: brownies, lemonade, cookies. Bring cash for everything.

For drinks: Heineken, Amstel, Bavaria — Dutch beer is omnipresent. Oranjebitter (orange-flavoured bitter liqueur) is the traditional King’s Day shot. Many bars sell only cans or plastic cups on the day (no glass on the streets). Public drinking is officially restricted in most of the city centre except on Koningsdag — this is one of the few days alcohol is allowed in the open street. For more on Dutch drinking culture, see our Dutch beer guide.

Getting Around on King’s Day

• Walking: your main mode of transport. Expect 15-20km on the day.
• Cycling: possible but crowded; experienced cyclists only. Don’t ride drunk — police give big fines.
• Trams & metro: most trams are suspended in the city centre. Metro runs but is packed.
• Trains: NS trains to and from Centraal run frequently; expect overcrowding.
• Taxis & Uber: extremely difficult — most of the centre is closed to vehicle traffic.
• Ferries: behind Centraal Station to Noord and NDSM run normally.

Practical advice: arrive in central Amsterdam by 10am latest — after that the trains get crammed. Plan walking routes that avoid the worst pinch points (Damrak, the eastern Jordaan, Reguliersgracht). The Magere Brug area is the most congested bridge in the city; if you need to cross the canal belt, use Brouwersgracht or Vijzelstraat instead. For broader transport context, our getting around Amsterdam guide covers normal-day transport.

Practical Tips for First-Timers

• Book accommodation 6+ months ahead: King’s Day is one of the busiest hotel weekends of the year. Prices triple. See our where to stay guide for neighbourhood picks.
• Stay in the centre or near a metro line: walking back to your hotel at 2am is part of the experience, but a 5km hike less so.
• Power-bank your phone: you’ll use it constantly and signal is patchy with the crowds.
• Toilet strategy: public toilets are scarce. Use bars (buy a drink), or pay-to-use pop-up toilets (€1-2). Women: there are far fewer toilet options than for men. Plan around it.
• Pickpocket awareness: large crowds = pickpockets. Wear a money belt or zipped front pocket. Don’t keep your phone in your back pocket.
• Drink water: hangover prevention. Bring a refillable bottle — Amsterdam tap water is excellent and free at public fountains.
• Sunscreen + rain jacket: April weather. Both.
• Plan a meeting point: phone signal fails in dense crowds; agree where to regroup if you lose your group.
• Bring earplugs: the music is loud everywhere, even in restaurants and on terraces.
• Don’t drive: roads are closed, parking impossible, drink-driving penalties severe.

King’s Day with Kids

King’s Day is genuinely family-friendly during the day, especially in Vondelpark, where the children’s vrijmarkt is one of the city’s sweetest annual traditions. Tips: arrive early (before 10am), bring small change so kids can shop at the children’s stalls, pack snacks and water, plan an exit before mid-afternoon as crowds and drunkenness build. Other family-friendly spots: Westerpark (day events but quieter than central Jordaan), Sarphatipark in De Pijp, and Oosterpark. Avoid Leidseplein, Rembrandtplein, and the canal-belt bridges with young children. For more, see our Amsterdam with kids guide.

What to Avoid on King’s Day

• The Red Light District after dark on King’s Night/Day — extra rowdy and not pleasant.
• Damrak — packed with intoxicated tourists, expensive bars, no atmosphere.
• Driving anywhere — many roads closed.
• Glass bottles in public — illegal on the day.
• Public drug use — coffee shops are open but consumption in public has been targeted by police on busy days.
• Wild swimming in the canals — illegal, dangerous, water quality drops with the boat traffic, and police hand out fines.

Weather on King’s Day

Late April in Amsterdam is unpredictable. Average daytime high is 13-15°C; lows around 5°C. Expect a mix of sun, cloud, and rain in any single day. Dress in layers: thermal base, T-shirt or jersey for the orange look on top, lightweight waterproof in your bag. Don’t believe weekly forecasts more than 3 days out. The party goes ahead in any weather — rain just makes locals more enthusiastic. For seasonal context, see our best time to visit Amsterdam guide.

King’s Day Outside Amsterdam

Every Dutch town and city celebrates Koningsdag, but each year the royal family visits one chosen town for the official ceremony. For 2027 the town will be announced in autumn 2026. Cities like Utrecht, Rotterdam, Den Haag, and Haarlem all host major celebrations and vrijmarkten too — Utrecht in particular is famous for its canal-side party and is a great alternative to Amsterdam if you want a smaller-scale version of the day. From Amsterdam, all four cities are 20-50 minutes by train (see our day trips from Amsterdam guide).

Frequently Asked Questions

When is King’s Day 2027?

Tuesday, 27 April 2027. (Always King Willem-Alexander’s birthday; shifts to the Saturday before if the date falls on a Sunday.)

Do shops and museums open on King’s Day?

Most shops are closed (it’s a national holiday). Major museums — Rijksmuseum, Van Gogh Museum, Stedelijk — typically remain open with normal hours. Anne Frank House also opens. Supermarkets in central Amsterdam often close or shorten hours; pick up groceries the day before.

Is King’s Day safe?

Yes — Amsterdam police are out in force, and despite the heavy drinking the atmosphere is overwhelmingly happy. Standard big-crowd precautions apply: pickpockets in dense areas, watch out for falling drunks, stay alert near canal edges (people fall in every year). See our Amsterdam safety guide.

Can I rent a boat for King’s Day myself?

Self-drive electric sloop rentals (Boaty, Boats4rent, etc.) typically don’t operate on King’s Day — the canals are too crowded for inexperienced captains. Book a skippered private charter or a public cruise instead, 2-3 months ahead.

What’s the difference between King’s Day and Liberation Day?

King’s Day (27 April) celebrates the king’s birthday. Liberation Day (Bevrijdingsdag, 5 May) commemorates the end of Nazi occupation in 1945, with free open-air concerts across the city. Both are public holidays a week apart.

Is one day enough?

Plan a long weekend: arrive 26 April for King’s Night, do the full Koningsdag on the 27th, recover on the 28th. Three nights is ideal.

Final Thoughts

King’s Day is the wildest, happiest, most memorable day in the Amsterdam calendar — a city of 900,000 people swelling to over 1 million, every street corner a party, every canal a flotilla, every neighbourhood different. It is also exhausting. The trick is to plan ahead (accommodation, boat, orange outfit), pace yourself, eat properly, and let the day unfold. Whether you spend it shopping the Jordaan vrijmarkt, drifting through the canals on a sloop, or sitting on the grass in Vondelpark watching kids play violin for tips, you’ll remember Koningsdag for the rest of your life.
