The name means "Sigalda's Canyon," but travelers and locals have given it a more poetic nickname: the Valley of Tears. The reason is immediately obvious. Dozens of thin waterfalls -- fifty or more, depending on the season and recent rainfall -- stream down the moss-covered eastern wall of the canyon, cascading into turquoise water below. The effect looks like the cliff itself is weeping.
What makes this even more remarkable is that these waterfalls were hidden for decades. When the Sigalda Hydroelectric Power Station was built in the 1970s, it diverted water and lowered river levels in the area, revealing the spring-fed cascades that had been submerged. In a sense, human engineering accidentally uncovered one of Iceland's most beautiful natural features.
Sigoldugljufur gained international attention through social media and drone photography in the 2010s, and visitor numbers have grown steadily since. A new access road built in 2021 improved 4WD access, making it one of the more reachable highland destinations. But it still requires an F-road-capable vehicle and a drive into the interior -- enough of a barrier to keep it far less crowded than the south coast waterfalls.
