Hiking to the Northernmost International Tripoint: Lake Goldajärvi's

The Three-Country Cairn, a historic boundary stone, resides at the tripoint where the international borders of Sweden, Norway, and Finland converge, being the northernmost international tripoint in the world. This monument was constructed in 1897, with Sweden adding their stone in 1901. The Three-Country Cairn sports a beige, conical frustum made of concrete statue-topped with a pile of stones and sits 10 meters (33 feet) out in Lake Goldajärvi. Measuring approximately 14 square meters (150 sq ft) with a diameter of about 4 meters (13 feet), this monument can be reached through a hike of 11 kilometers (6.8 miles) from Kilpisjärvi in Finland, or by a public boat to Kilpisjärvi followed by a 3-kilometer (1.9-mile) walk. Alternatively, it can be accessed from Norway, commencing from a hiking trail starting at road E8 near the border.
