Camden's Adventure Aquarium, Sharks, Hippos, and Much More

The Adventure Aquarium makes itself unique not just by the amount of sea creatures you can touch, but they also have hippos.

The aquarium itself is located on the Camden Waterfront, a beautiful area in spite of all the bad publicity the city receives. Upon arrival you will be greeted with a spectacular view of Philadelphia, just across the Delaware River. Adjacent to the aquarium is the baseball stadium for the Camden Riversharks, which sits just below the Ben Franklin Bridge. A little farther up the waterfront sits the Battleship New Jersey, so if the aquarium isn't enough to fill your day there is much more to be seen.

The way Adventure Aquarium sets itself apart from other aquariums is the way they present the sea creatures and animals. While the walls contain glass panels to look into the underwater world of a variety of sea creatures, they seem to know just which of these creatures you would most want to check out, and make those experiences unforgetable. This is done through many touch-tanks, multiple level displays and even a tunnel.

The spot you may find yourself most amazed is the 40 foot shark tunnel. Here, you literally walk through a tunnel in the 550,000 gallon shark tank which holds over 20 sharks and 850 other creatures. It is like you are under the sea with them, in their world, yet safe and dry. Don't be surprised if you see a few divers in the tank among the sharks, the aquarium hosts swim- with- the- sharks experiences by appointment.

A favorite of the children are the four touch areas located throughout the aquarium. Moon Jelllyfish, Freshwater Stingrays, the Hardbody Pool featuring Hermit Crabs, Horseshoe Crabs, Lobsters, and Sea Stars, and the very popular Touch-A-Shark exhibit. Here you can reach into the shallow pool containing Pacific Brown-Banded, White-Spotted Bamboo, and Smooth Dogfish sharks and touch their backs as they swim by.

As all aquariums do the Adventure Aquarium has the standard favorites of all, seals and peguins. Here again the difference is in how they are presented. Both exhibits are set up as two level displays, meaning you can not only watch them on the surface, but also swimming below. Children love to follow them as they transition from the land to the water and vice versa. A special treat is to be in these areas during feeding time. Check the schedules and make a point of getting there early as it draws quite a crowd.

The biggest, and I mean literally, surprise of the aquarium is the Rainforest area, which not only houses an array of birds, but also two hippos. These animals are huge, each weighing in at more than the average car. A small wall is all that separates you from them, and here again you can see them on land and in the water. Adding to the experince is the noise of the birds flying overhead. Fish in an aquarium yes, but birds, and hippos too? At the Adventure Aquarium this is all part of the daily experience.

The aquarium is open 365 days a year from 9:30AM to 5:00PM. Admission is $22.95 for adults, $17.95 for children ages 2 to 12, and children under 2 are admitted free. The aquarium often hosts groups such as school children so you may want to check the website for best times to visit. They also recommend you purchase your tickets in advance at www.adventureaquarium.com to avoid possible long lines at the ticket office.
