General admission costs at the National Aquarium
The National Aquarium in Baltimore charges $29.95 for adults, $24.95 for children ages 3 to 11, and $27.95 for seniors 65 and older. Children under 3 enter free. These are the standard walk-up prices at the ticket window or online.
Prices can shift seasonally and during special events, so checking the aquarium's website before your visit is worth the minute it takes. The aquarium is located at 501 East Pratt Street in Baltimore's Inner Harbor, and parking in the area runs separately — expect to pay $10 to $20 depending on which lot you use.

Discounts and ways to lower the ticket price
Buying tickets online before you arrive usually saves money compared to the ticket window. Third-party discount sites sometimes offer reduced rates, though the savings are typically $2 to $5 per ticket. Check the aquarium's official website first to see if they have their own online discount or package deals.
If you live in Maryland, some employers and credit unions offer discounted aquarium tickets through their benefits programs. The Baltimore Public Library also distributes free or reduced-price passes to cardholders on certain days. Call your library branch to ask whether they have passes available and what the current rules are.
Military personnel, first responders, and some government employees may receive discounts. Bring a valid ID to the ticket window to ask what your rate would be — the aquarium's website lists which groups may have access to, but rates and terms change.
Annual membership versus paying per visit
An annual membership costs around $99 for an individual and includes unlimited visits, free parking, and discounts at the gift shop and café. If you plan to visit three or four times in a year, the membership pays for itself. Family memberships run higher but spread the cost across multiple people.
Members also get early access to special exhibits and invitations to members-only events. If you live in the Baltimore area and enjoy the aquarium, membership is usually the better financial choice than buying individual tickets each time.
Special events and evening hours pricing
The aquarium sometimes stays open later on certain nights and charges a different rate for evening admission. These hours are not daily and vary by season. Prices for evening visits are sometimes lower than daytime rates, sometimes higher — it depends on what the aquarium is offering that night.
Special exhibits, like temporary animal displays or interactive experiences, may require an additional fee on top of general admission. The aquarium's website lists upcoming special events and their costs. If you are planning a specific visit around a particular exhibit, check ahead so you know the total price.
Group rates and school visits
Groups of 15 or more people usually receive a per-person discount. Schools and organized groups can arrange guided tours, which have their own pricing separate from general admission. Contact the aquarium's group sales department directly for a quote — rates depend on group size and the type of experience you want.
Many schools in Maryland use the aquarium for field trips, and the aquarium works with educators to set up programs. If you are organizing a group visit, calling ahead is essential because availability fills up, especially during the school year.
What is and is not included in your ticket
Your admission ticket covers access to all the main exhibits, including the tropical rainforest, shark alley, and the open ocean tank. It does not include food, beverages, or items from the gift shop. The café inside charges restaurant prices — expect to spend $12 to $20 on a meal or snack.
Parking is separate and not included. Some special experiences, like touch pools or behind-the-scenes tours, may cost extra. Bring cash or a card, because the aquarium accepts both, though card payment is more common now.
Planning your visit and saving money
Visit on a weekday rather than a weekend if you can — crowds are smaller, and you will spend less time waiting in line. The aquarium is open year-round, and admission prices do not change with the season, though hours may.
Pack snacks and water in a bag if the aquarium allows outside food — this cuts down on café spending. Bring a reusable water bottle to fill at fountains inside. If you are local or plan multiple visits, the annual membership remains the single biggest way to reduce your per-visit cost.
Frequently Asked Questions
Do children under 3 really get in free?
Yes. Children under 3 do not need a ticket. You will still need to show proof of age at the ticket window or gate if asked. Bring a birth certificate or ID if you have it handy, though the aquarium rarely checks.
Can I get a refund if I buy a ticket and don't go?
Refund policies vary depending on where you bought the ticket and when. Tickets bought directly from the aquarium are usually non-refundable, but you may be able to use them on a different date. Check the terms when you purchase, or call the aquarium to ask about your specific ticket.
Are there free days at the Baltimore Aquarium?
The aquarium does not have regular free admission days. However, some Maryland residents may access free or reduced passes through the Baltimore Public Library. Call your local branch to ask if passes are available and what the rules are for your area.
What time of year is cheapest to visit?
Admission prices stay the same year-round, but visiting on a weekday in fall or winter means smaller crowds and shorter lines. You will not save money on the ticket itself, but you will spend less time waiting and may enjoy the experience more.
Can I bring my own food and drinks?
Outside food and drinks are typically not allowed inside the aquarium. The café is your main option for meals. Bring a refillable water bottle — you can fill it at fountains throughout the building.
