The National Aquarium is the crown jewel of the Inner Harbor in Baltimore, Maryland. The waterfront facility allows visitors of all ages to get up close and personal with 17,000 animals from around the world, including more than 660 aquatic species from the deep ' and not-so-deep! See dolphins at play in the Dolphin Discovery exhibit, walk alongside menacing and mysterious sharks in Shark Alley and check out jellyfish of all shapes and sizes in the Jellies Invasion.

Guests can also experience the wonder of two living coral reefs, a tropical rainforest, waterfront park with access to Maryland's indigenous ecosystems, interactive touch-pools and other stunning exhibits.
