Kangilinnguit, known as Kangilínguit or previously Grønnedal, is a locale in the Sermersooq municipality of Greenland. Situated at Arsuk Fjord's entrance in the southwest, it was established as 'Green Valley' by the U.S. Navy in WWII to safeguard the vital cryolite mine at Ivittuut."The port is situated at the entrance of Arsuk Fjord, provides stunning vistas and a variety of outdoor pursuits like hiking and boating. Its historical importance, especially its involvement in World War II, enhances its allure for tourists. It’s worth noting that the naval base was decommissioned in 2012 and remaining military operations were relocated to Nuuk, Greenland’s capital.
