• About 40 minutes by car from Copenhagen, with a large free car park by Museum Island; from Roskilde Station it's a 20 to 25 minute walk or bus 203
• Summer is the full visit, with harbor ships to board and daily boat trips with oars and sails May to September; in winter those close and the boatyard opens weekdays only
• Stairs in the hall, so ask at Information on arrival to bring a stroller into the Viking Ship Hall through the rear entrance

The museum is built around five original Viking ships, sunk in Roskilde Fjord to block a sea route about a thousand years ago, then raised in one of Denmark's major excavations. A giant window frames the fjord behind them.

Kids can climb aboard two full-size Viking ships as a light-and-sound storm rolls across the walls, play in a Viking children's village, and watch boatbuilders at work on Museum Island.
