Kulusuk (old spelling: Qulusuk[3]), formerly Kap Dan, is a settlement in the Sermersooq municipality in southeastern Greenland, located on an island of the same name.

The highest point on the island is the summit of Qalorujoorneq, at 676 m (2,217.8 ft)[5] topping a wide mountain massif in the southeast, directly above the airport.

As of 2013, Kulusuk is the third-largest settlement in the region, after Tasiilaq and Kuummiit, and the fourth-largest on the eastern coast,[1] although the number of villagers dipped below 300 in the late 2000s.

In 2009 the village received permission from the Sermersooq municipal authorities to convert the old Royal Greenland fish processing plant for school use.

Day trips organized by the hotel and Icelandair focus on the traditional culture of eastern Greenland, including drum dance performances and dogsledding.

It provides direct connections to Nuuk on the western coast, Reykjavík in Iceland, and Tasiilaq on Ammassalik Island, which links many other villages in the region through settlement helicopter flights.

[15] In the summer, the cargo boats of Royal Arctic Line connect Kulusuk and Tasiilaq,[16] providing an ad hoc alternative for the helicopter flights of Air Greenland.

[5] In the winter, the inhabitants of the village use snowmobiles and traditional dogsleds as additional means of transport – families arriving at the airport are ferried to the settlement on both.

Neighboring Tasiilaq – where the main local weather station is located – holds the settlement windspeed record for Greenland: on 7 February 1970 the speed peaked at 54 m/s or 194 km/h.

[20] Pack ice and small icebergs pushed forth by the East Greenland Current ram against the northeastern coast, blocking the Ikaasaartik Sound and facilitating the freeze of the wider Torsuut Tunoq waterway.

Even though Kulusuk lies approximately 110 km (68.4 mi) south of the Arctic Circle, the celestial phenomenon of Aurora borealis can still be observed in the village.
