We visited on a very cold day during the winter. Many of the outdoor exhibits, including the penguins, were closed. It was fun but I would go in warmer weather.

This was our first time visiting the Long Island Aquarium but certainly won't be the last. Allow at least a half day minimum to get the most out of your visit. This is especially helpful if you plan on attending any of the various programs...More

Great place but very expensive for a big family. The best part was the manager, Charles, who runs the butterfly room. It was a wonderful experience.

You can rush through in an hour, but typically it will take between 3-5 hours to see everything there is to see. Don't miss the Sea Lion shows and our schedule Talk & Feed lecture series.
