Flókadalur (pronounced as /is/) is both a valley and region in Skagafjarðarsýsla that was named after Flóki Vilgerðarson, who is said to have settled the land there when he returned to Iceland, and gave the land its name.
In front of Flókadalur is the lake Hópsvatn in Icelandic pronounced as /ˈhoupsˌvahtn̥/, which is separated from the sea by a low, gravelly isthmus. Inside the valley is Flókadalsvatn in Icelandic pronounced as /ˈflouːkaˌtalsˌvahtn̥/. Through Flókadalur runs Flókadalsá in Icelandic pronounced as /ˈflouːkaˌtalsˌauː/. Several towns are in the valley, which is grassy but snowy in the winter.
