The National Aquarium’s floating wetland project will be located in between Piers 3 and 4 of the Inner Harbor.

The National Aquarium’s long-awaited floating wetlands project plans to debut next year in between Inner Harbor’s Piers 3 and 4. The floating wetlands idea was first announced in early 2016 with a completion date in 2022 but was derailed during the Covid-19 pandemic. The project, which is still estimated to cost $14 million, is now back on track for a mid-2024 opening and will include 10,000 square feet of floating wetlands with a 5,000-square-foot dock.
