National Maritime Museum

National Maritime Museum is a Greenwich museum about Britain's relationship with the sea, from exploration and navigation to the people behind maritime trade. Its broad collection gives adults and children different ways into the same stories without requiring a shipboard visit.

Choose a manageable set of galleries and allow one to three hours, using the current visitor map to find age-appropriate displays. This is a separate venue from Cutty Sark and the Royal Observatory, so plan its entrance and visit on their own terms rather than assuming one ticket covers the whole area.

General admission is free and advance booking is recommended. Selected exhibitions and activities may need separate tickets. Check the current programme before promising a particular family session, and use this indoor visit when outdoor Greenwich plans are less appealing in poor weather.
