General admission prices at the National Aquarium

The National Aquarium in Baltimore charges $29.95 for adults, $24.95 for children ages 3 to 11, and $24.95 for seniors 65 and older. Children under 3 are free. These are the walk-up prices at the ticket window; online prices are sometimes lower by a dollar or two, depending on the day you visit.

Prices vary slightly by season. Summer months (roughly June through August) and holiday weeks tend to be at the higher end. Weekday visits in fall and winter are often cheaper. The aquarium's website shows the exact price for your chosen date when you select it, so you can compare before you buy.

Parking at the aquarium's lot costs $15 for the day. Street parking is available nearby but fills quickly, especially on weekends. If you plan to visit more than once a year, membership starts at around $99 for an individual and includes unlimited visits, guest passes, and discounts at the gift shop.

Discounts and reduced-price days

Maryland residents get a discount on certain days. The aquarium offers reduced admission on select Thursdays and Fridays for people who show a Maryland ID at the ticket window. The discount is usually $5 off adult admission. Check the aquarium's website for the current schedule, as participating days change seasonally.

School groups and organized tours receive group rates if you book in advance. Groups of 15 or more typically pay less per person than individual walk-up rates. Contact the aquarium's group sales team directly for a quote based on your group size and visit date.

The aquarium occasionally runs promotions around holidays or special events. These are advertised on their website and social media, but they are not may provide year-round. If you are flexible with your visit date, checking the website a few weeks ahead can reveal whether a discount period is coming.

What is included in your ticket

Your admission covers access to all the main exhibits: the tropical rainforest, the open ocean tank, the jellyfish gallery, the seahorse area, and the shark and ray touch pool. You can spend as much time as you want in each section. Most visitors spend 2 to 3 hours moving through the exhibits at a comfortable pace.

The ticket does not include special experiences like the dolphin encounter or the behind-the-scenes tour. Those are add-ons that cost extra and must be booked separately. The gift shop and cafeteria are also separate from admission — food and souvenirs cost additional money.

Parking is not included in admission and must be paid separately unless you have a membership. Some memberships include parking, so check the membership tier details if you are considering that option.

How to buy tickets online versus at the gate

Buying online through the aquarium's website is usually faster and sometimes cheaper. You select your date and time, pay, and receive a confirmation email with a barcode. You skip the ticket line and go straight to the entrance. Online tickets are typically valid for 30 days from purchase, so you have some flexibility if your plans change.

Buying at the gate works if you are already there, but you may wait 15 to 30 minutes during busy times, especially on weekends and school holidays. Gate prices are the full walk-up rate, which is higher than many online deals. If you know your visit date in advance, buying online is the better choice.

Some third-party ticket resellers offer discounts, but verify they are legitimate before handing over payment. The aquarium's official website is the safest source and often has the best deals for your specific date.

Special events and evening hours

The aquarium stays open later on certain evenings and hosts special events like "Dive In" movie nights or holiday celebrations. These events usually cost more than regular admission — sometimes $15 to $20 extra — but include food, drinks, or entertainment beyond the standard exhibit access. Details and dates are posted on the aquarium's events page.

School field trips and private rentals are also available. A private after-hours rental for a group starts around $3,000 to $5,000 depending on group size and what you want included. These are booked through the group sales team, not through regular ticket channels.

Planning your visit and what to bring

Bring comfortable shoes because you will be walking and standing for several hours. The aquarium is indoors and climate-controlled, so dress for that rather than the weather outside. A camera is allowed, though flash photography is prohibited in some exhibits to avoid stressing the animals.

Food and drinks from outside are not permitted, but the aquarium has a cafeteria with sandwiches, salads, and snacks. Prices are typical for a museum venue — expect to pay $12 to $18 for a lunch entree. Bringing your own water bottle (empty, to fill at fountains) saves money.

The aquarium is located at 501 East Pratt Street in Baltimore's Inner Harbor. Parking is available in the lot directly adjacent to the building, or you can use public parking garages nearby. Public transit (the light rail and bus lines) also serve the Inner Harbor area if you prefer not to drive.

Membership and annual pass options

An individual annual membership costs around $99 and includes unlimited visits, 20% off the gift shop, and discounts on special events and dining. A household membership (two adults and up to four children) runs around $179 and covers the same benefits for everyone on the membership. Both types include guest passes, which let you bring friends or family at member rates.

If you visit more than three times a year, membership usually pays for itself. The math is straightforward: three visits at $29.95 each equals about $90, so a $99 membership breaks even on the fourth visit. If you live in the Baltimore area or plan multiple trips, it is worth calculating based on your expected visits.

Membership also includes reciprocal benefits at other aquariums and zoos across the country through the Association of Zoos and Aquariums (AZA) reciprocal program. This means you may get free or discounted admission to partner institutions if you travel.
