Anyone visiting this fair city has to make sure they save at least a portion of one day for this wonderful aquarium. It is multi-leveled and includes many areas of interest, from sting rays and sharks, freshwater pond life, rain forests, the ocean, and so on. You won't be disappointed or bored. The only thing that might put you off are the crowds, so arrive as early in the day as possible. They generally open at 9:00 a.m. and close at 6:00 p.m. Admission is $17.50 for adults, $9.50 for children, and $14.50 for senior citizens (60 and over). The Aquarium has its own food/snack facilities inside, or you can get your hand stamped to get something to eat in the Harbor area, and then return to finish your tour. It is self-guided, but there are special tours which you can pay extra for that take you behind the scenes of the Aquarium. These usually include breakfast or lunch. It will give you a chance to see the behind-the-scene workings and avoid some of the crowds, also. The Aquarium is located on Pier 3 at 501 E. Pratt St. in Baltimore. Tickets can be purchased ahead of time through TicketMaster or the Aquarium Ticket Center, up to 30 days in advance using the Automated Ticket Teller Machines, or at the Will Call window.
