This aquatic wonderland, open 365-days-a-year, offers kids and grown-ups alike the opportunity to explore sealife of all shapes and sizes. Adventure Aquarium is located just across the river from Philadelphia (you can see it from the waterfront), and is a great side trip to entertain, educate and explore with kids. What kinds of life can you see here? They've got penguins, sharks, hippos, stingrays, birds, reptiles, turtles, crocodiles and a ton of fish ranging from the angelically beautiful to the hideously ugly, the harmless to the dangerous, and everything in between. If you've got a sealife lover, or if you just want a fun day out, take a trip to Adventure Aquarium.
