NEMO Science Museum
You can spot NEMO from across the harbor: a big green building shaped like a ship's prow tilting up out of the water, designed by Renzo Piano. Inside is five floors of hands-on science aimed squarely at kids, the kind of place where they blow bubbles bigger than themselves and chase electricity around a room. But here is the part a lot of people miss. The sloping roof is a free public terrace with one of the best wide views in the city, and you do not need a museum ticket to go up there.

A genuinely good hands-on science center for families, and a free rooftop view that everyone else should come up for regardless.
Worth it for
- Parents with kids aged 6 to 14 who need an active, weatherproof afternoon
- Anyone walking the harbor who wants a free panoramic terrace and a coffee with a view
You can skip if
- You are traveling without children and only care about the exhibits, not the building or the roof
- You want quiet; on rainy weekends the inside is loud and packed
Tickets & tours for NEMO Science Museum
Which ticket should you buy?
What it actually is
NEMO is a science center, not a museum of objects behind glass. Everything is built to be pushed, pulled, mixed, and set off. The exhibits run from chain reactions and water locks to a teen lab about hormones and identity, and most of it works on the principle that you learn a thing by doing it badly a few times first. If your kids are roughly 6 to 14, this is close to a perfect rainy afternoon.
Younger toddlers and adults traveling without children get less out of it. The signage is bilingual and clear, but the energy is loud and busy, and on a wet weekend it can feel like every family in Amsterdam had the same idea. It is a great place. It is not a quiet one.
The free rooftop
The roof is the reason to come even if you skip the museum entirely. It steps up in wide terraces with greenery, a butterfly garden, water features kids can play in on a warm day, and a long view back over the old harbor toward the city center. There is a cafe and a bar up there too, so you can sit with a drink and the skyline for the price of the drink.
Access is free and separate from museum admission. You climb the broad outdoor staircase on the east side, or take the lift up from the museum foyer to the top floor. The roof keeps its own hours and closes earlier than you might expect, usually late afternoon, with longer Thursday evenings in the summer months. Check before you make a special trip up for sunset, because in midsummer the roof may shut before the sun does.
Getting in and timing it
Museum tickets are timed and cheaper booked online ahead of your visit, and on busy holiday periods slots do sell out, so do not count on walking up at noon on a rainy Sunday and getting straight in. Buy for a morning slot if you can. The crowds thicken as the day goes on and the building gets warm and loud by mid-afternoon.
The roof, again, needs no ticket and no booking. If all you want is the view, just walk up. That makes NEMO an easy add-on to a harbor stroll even on a day when you have no intention of paying to go inside.
Where it sits
NEMO stands over the entrance to the IJ tunnel in the Oosterdok, an easy and pleasant 15-minute walk east from Centraal Station along the water. You pass the public library and the maritime museum on the way, both worth a look.
The neighborhood around it is open and modern rather than canal-pretty, which actually helps the views: there is nothing tall blocking the roof's sightlines back toward the historic core. Pair it with the science center, the nearby library's own free rooftop cafe, or the Maritime Museum next door for a full half-day on the water.
NEMO Science Museum: FAQs
Yes. The roof terrace is open to the public at no charge and does not require a museum ticket. You reach it by the outdoor stairs on the east side or the lift in the foyer.
For the museum itself, yes, ideally. Entry is timed and works out cheaper online, and slots can sell out during school holidays and wet weekends. The roof needs no booking at all.

Walk. It is about 15 minutes east along the waterfront, past the central library. There is no need for a tram or metro.
Sometimes, but the roof closes in the late afternoon and in high summer it may shut before sunset. There are longer Thursday evening hours in summer, so check the current times if that is your plan.
