Overnight Adventure

Spend an unforgettable night at the Aquarium! When the sun goes down, the Aquarium comes to life. This after-hours adventure takes you around the Aquarium to learn about the 20,000-plus animals that call the Aquarium home.

Following a kid-friendly dinner, journey to a tropical rain forest, discover dolphins, see shark-filled waters and even explore behind-the-scenes areas with one of our expert guides. At our interactive adventure stations, you’ll get a first-hand look at what it takes to run an aquarium.

As you adventure winds down, help us say goodnight to the Aquarium before heading to bed. After a quick breakfast, you’ll set off on one last adventure featuring an interactive game to showcase the awesome explorer you’ve become!

Frequently Asked Questions

Does my tour go behind-the-scenes?

Yes! You’ll visit behind-the-scenes areas during your tour.

How old do I have to be to go on this tour?

Because of the behind-the-scenes access, all participants must be at least 8 years old. No refunds will be given for guests who do not meet the minimum age requirements to participate.

Can my child participate without a parent or guardian?

A parent or guardian must accompany all participants under the age of 16. Minors 16 years of age or older may participate with a signed waiver from a parent or guardian. Parents or guardians accompanying children must be at least 18 years old. For example, a 17-year-old may attend a tour with a signed waiver, but their 10-year-old sibling may not accompany them without an adult.

Will I get to touch any animals?

Not all of the animals you’ll see on your tour are available for guest interaction. We try to bring you as close to our animals as possible, but for both your safety and that of our animals, we cannot guarantee the opportunity to touch or handle an animal.

What should I wear?

You’ll be traveling behind the scenes, so close-toed, non-slip shoes are required. That means no crocs, sandals, flip-flops or high heels. We recommend wearing comfortable clothing, as you’ll be traveling around the Aquarium. Sleepovers are co-ed, so make sure to bring comfortable sleep attire that’s appropriate for a co-ed group.

What should I bring with me?

  • You’ll be camping on the floor, so bring a sleeping bag! Sleeping pads, pillows, and foam or air mattresses are optional, but due to limited space, we encourage guests not to bring air mattresses. Air mattresses larger than twin-size and cots are prohibited.
  • You’ll be spending the night, so bring toiletries and personal articles, such as a toothbrush, toothpaste, washcloth, facial soaps, medications and sleepwear suitable for a co-ed group.
  • Remember that close-toed, non-slip shoes are required. That means no crocs, sandals, flip-flops or high heels.
  • You may also wish to bring money if you plan to visit the Aquarium's gift shop. Please note that shopping time is not included in the schedule. We recommend arriving early, or planning to re-enter the Aquarium after your sleepover is over, if your group would like to visit the gift shop.

Is admission included with my tour?

Yes! You’re free to explore the Aquarium during our regular hours before or after your sleepover. To enter the building, please use the Pier 3 Staff Entrance located directly across from the U.S.S. Torsk submarine. We will not be able to store your gear prior to your scheduled check-in time or following your sleepover, so be sure to store your gear in the car if you plan to explore the Aquarium!

If I decide to visit the Aquarium before or after my sleepover, is there a place to store my gear?

No. We will not be able to store your gear prior to your scheduled check-in time or following your sleepover, so be sure to store your gear in the car if you plan to explore the Aquarium!

Are sleepovers coed?

Yes. Our sleepovers are best described as indoor camping experiences and are open to any and all groups, so they may be co-ed. If your group wishes to have a private sleeping area, please let your sleepover guide know during check-in. We will do our best to accommodate the needs of each group, but we cannot guarantee that a private sleeping area will always be available.

Will there be food or snacks during the sleepover?

Yes! During your sleepover, you’ll have the chance to dine with us twice. A kid-friendly, buffet-style dinner and a continental breakfast are both included with the cost of your tour. If you or someone in your group has special dietary needs, please contact us at 410-576-8822, and someone will be in contact regarding options for you or your group!

Do you offer badges for scout groups?

Yes! All of our scout groups receive a National Aquarium patch. However, at this time, it is not an official scout badge. Please check back soon, as we’re working on some sleepover additions that will allow your scouts to earn different badges during their visit.

Is there a chaperone to child ratio for sleepovers?

Yes! We require at least one adult (18 years or older) for every seven children under the age 16.

Where should we park when we arrive, and are there any discounts available?

When you arrive for your sleepover, please plan to park at the Lockwood Garage (124 Market Place Baltimore, MD 21202) located directly across the street from the National Aquarium. Remember to bring your parking ticket to check-in. Your sleepover guide will provide you with a chaser ticket to use upon exiting the garage with a flat rate of $8. To receive this discount, you must exit the garage prior to 12:00 pm following your sleepover.
