Seattle Aquarium Tickets: Prices & How to Save

The Seattle Aquarium is one of the city’s most popular family attractions, and a single adult ticket runs around $50 in 2026. That’s a fair price for a half-day indoors — but if you’re seeing more than one Seattle sight, a pass almost always beats buying a standalone ticket. Here’s what admission costs, when to go, and how to pay less.

What you get for the price

The Seattle Aquarium sits right on the downtown waterfront at historic Pier 59 and Pier 60, a short walk from Pike Place Market. In 2024 it opened the Ocean Pavilion, a striking expansion that added large tropical-reef habitats and a sweeping oceanarium view — and one admission ticket now covers the whole site: Pier 59, Pier 60, and the Ocean Pavilion together.

It’s a genuinely family-friendly outing. Highlights include:

• Sea otters and harbor seals, with daily feedings that kids line up for.
• The giant Pacific octopus, a Puget Sound local and a crowd favorite.
• Local marine life — the touch-friendly tide pools, salmon, and the underwater dome that puts you inside a Northwest reef.
• The Ocean Pavilion’s coral reef, the newest and most photogenerous addition.

Plan on roughly two to three hours. Because it’s fully indoor, it’s also one of the best rainy-day picks in a city that has plenty of gray afternoons.

Seattle Aquarium ticket prices in 2026

The aquarium uses variable (demand-based) pricing, so the exact number shifts with the date and how busy the day is expected to be. As a rule of thumb:

• Adult (13+): around $50 — roughly $41 to $49 direct, and about $49.95 as the standard retail rate.
• Youth (ages 4–12): around $25 to $29.
• Children 3 and under: free.

Prices are lower midweek and higher on busy weekends and holidays, and booking a couple of weeks ahead usually locks in the cheaper end of the range. Everything is mobile — tickets live on your phone.

Why tickets add up fast for a family

At around $50 per adult and roughly $27 per child, a family of four is looking at $150 or more just for the aquarium — before you’ve done a single other thing in Seattle. And most visitors don’t stop at the aquarium; they also want the Space Needle, a harbor cruise, or Chihuly Garden and Glass. Once you’re paying separate gate prices for three or four attractions, the total climbs quickly. That’s exactly where a pass changes the math.

The best time to visit

For the shortest lines, the cheapest tickets, and the calmest galleries, go early on a weekday:

• Mornings — the aquarium is quietest right at opening, before school groups and mid-day crowds arrive.
• Weekdays over weekends — Tuesday through Thursday tend to be both less crowded and lower-priced.
• Off-season — fall and winter weekdays are the quietest of all, and the indoor setting makes weather irrelevant.

Booking online in advance is worth it either way: you skip the ticket window and often catch the lower demand-based price.

How to save with a Seattle pass

Here’s the money angle. The Seattle Aquarium is a standard feature on the city’s two main sightseeing passes, so if you’re doing more than one attraction, buying through a pass is almost always cheaper than a standalone ticket.

• Seattle CityPASS — the aquarium is always included, no choosing required. The CityPASS costs about $139 for an adult and ~$119 for a child and bundles five attractions total, saving up to 47% versus gate prices. Since the aquarium is baked in alongside the Space Needle, its ~$50 ticket is effectively absorbed into the bundle. See what the Seattle CityPASS includes for the full lineup.
• Seattle C3 — at around $108, C3 lets you pick any three attractions, and the Seattle Aquarium is one of the choose-from options. If you want just the aquarium plus two other picks, C3 is often the leaner deal.

Put simply: a standalone aquarium ticket costs around $50 and gets you one attraction. For roughly the price of two-and-a-half aquarium tickets, the CityPASS gets you the aquarium plus four more of Seattle’s headline sights. The more you plan to see, the more lopsided that comparison becomes.

Should you buy a ticket or a pass?

A quick decision guide:

• Aquarium only, single visit: buy a standalone ticket — book ahead on a weekday morning for the best price.
• Aquarium plus one other sight: compare a standalone ticket against C3; the pass often edges ahead.
• Aquarium plus two or more sights: a pass wins clearly — the CityPASS or C3 will beat separate gate prices, and the aquarium comes bundled in.

Bottom line

Seattle Aquarium tickets cost around $50 for adults and $25–$29 for kids in 2026, with variable pricing that rewards booking early on a quiet weekday. For a family, or for anyone pairing the aquarium with even one more attraction, a pass is the smarter buy — the Seattle Aquarium is always on the CityPASS and a choose-3 option on C3, so it comes out cheaper as part of the bundle.

Before you decide, compare current pass prices against a standalone ticket and see which fits your itinerary. Many booking options include free cancellation, so you can lock in today’s rate and finalize your plans later.
