• Dream Ship play area for ages 3 to 12, with sailor karaoke, a sailor's workshop and captain and lighthouse keeper costumes
• Kronborg Castle next door, so the castle and the museum fit into one day in Helsingør
• Galleries below sea level inside the walls of the old dry dock, a good pick for a wet or cold day

The museum tells Denmark's seafaring story in galleries below ground, built around a former dry dock beside Kronborg Castle. Interactive exhibits let kids play an 18th-century merchant, navigate with traditional tools and get a washable sailor's tattoo.

The Dream Ship play area is a toy 1950s motor ship where kids crawl through the engine room, load cargo, ring the engine-room telegraph and make their own boats from rope and sails.
