Aquariums in Seattle, WA
Looking for aquariums in Seattle? Here are 6 of them, with the details parents check first: price, opening hours and the right age range.
Sorted by distance from Seattle, nearest first. Those are straight-line miles, so every drive is longer than the number on the card.
Where a card says no price or no hours listed, the venue does not publish it. We would rather leave the gap than fill it with a guess. Prices come from each venue's own website, and we publish one only when the figure appears on the page we took it from. Tell us if we are missing one you know.

Before you go
Grip socks. Almost every venue requires them for children and several require them for adults. Most sell them at the door for a few dollars. Bringing your own is cheaper and means you are not buying a fourth pair.
Check whether adults pay. It runs from free to full price and it changes the cost of a visit by a lot when there are two of you.
Weekday mornings are the toddler rush. If you want space, aim for after two on a school day. Weekend mornings are the busiest hours of the week almost everywhere.
Ninety minutes is the realistic ceiling for most children under five. There is rarely a gradual wind down. Leaving with time left on the clock is not wasted money, it is a better afternoon.
Call ahead in school holidays. Several of these venues run camps and private events that close open play with no notice on the website.

Common questions about aquariums in Seattle
How many aquariums are there in Seattle?

Which aquariums in Seattle publish their prices?
1 of the 6 here do, and each price was checked word for word against the venue's own page before we published it. The rest do not publish one, so their card says no price listed rather than carrying a guess.

How did Mini Navigators choose these aquariums?
We list every one we have within 82 miles of the center of Seattle. Each is a published place with an address we geocoded and checked, and the business can claim its listing to keep the hours and prices current.
Do adults have to pay?
It varies more than you would expect, from free to full price, and it changes the cost of a visit by a lot when there are two of you. The price on each card is what it costs to get a child in. Where a venue publishes an adult price it is on the listing, and where it does not we have left it out rather than assume.
Do I need to book ahead?
Usually not for open play, but several venues cap capacity at weekends and during school holidays, and some close open play entirely for private events. Where a venue has its own booking page, the listing links straight to it.
What should I bring?
Grip socks, a water bottle, a change of clothes for anyone under four, and a plan for leaving before the meltdown rather than after it.

Seattle has 18 categories of kid-friendly places on Mini Navigators, from playgrounds and museums to splash pads and zoos. The Seattle hub lists all of them.
