Hillerød Slotssø Days & Denmark's Most Beautiful Longboat Regatta

Expect entertaining rowing in historic long boats, plenty of music in the streets, late-night shopping on Friday, a market square, and family-friendly entertainment, including balloon artists, a raffle, pony rides, bungee jumping, and clowns.

Historic longboat regatta on the Castle Lake

One of the highlights is the competition in rowing on Castle Lake. A long boat is a rather heavy, open workboat that was part of the equipment on naval ships in the 1700s and 1800s. Companies, associations, political parties, and citizen teams compete against each other in these beautiful boats to win the prestigious "oar," and it's delightful entertainment for the cheering spectators on the lake shore. In the evening, there is a dinner that everyone can participate in.

Hillerød Castle Lake Days bring the town together

On the weekend of June 19th to 21st, 2026, the town gathers around the pedestrian streets, SlotsArkaderne, and, most importantly, the beautiful Castle Lake for the 3-day duration of Hillerød Castle Lake Days. | See the entire program and learn more at www.hillerod.nu
