Standing seven stories high and capped by a glass pyramid, this is widely considered to be America's best aquarium, with almost 20,000 creatures from more than 700 species, a rooftop rainforest, a multistory shark tank and a vast re-creation of an Indo-Pacific reef that is home to blacktip reef sharks, a green sea turtle and stingrays. There's also a reconstruction of the Umbrawarra Gorge in Australia's Northern Territory, complete with 35ft waterfall, rocky cliffs and free-roaming birds and lizards.

　　The largest exhibit does see seven bottlenose dolphins kept in captivity. However, the aquarium is planning to retire them to an oceanside sanctuary as soon as it is safe to do so (freeing them to the wild is not an option, since they lack survival skills). Pollution and climate change challenges need to be worked through before the move. You'll be glad to read that the dolphins no longer perform in shows here.

　　Inner Harbor is where many Baltimore tourists start and, unfortunately, end their sightseeing. This waterfront-renewal project of shiny glass, air-conditioned malls and flashy bars has managed to capture the maritime heart of this city. There are also several impressive historic ships moored here.
