Use Stöng as a place name carefully

Protected landscape, separate waterfall approaches

Gjáin is a natural monument within the Þjórsárdalur landscape protection area, designated in 2020. Nearby Háifoss uses Road 332, and Hjálparfoss uses Road 3361; the names appearing in one protected area do not make them one parking stop. Use the official access map and current road conditions to decide what fits your day.

Gjáin’s May 2026 drone-permit policy excludes recreational applications. Plan to photograph it from the open visitor paths.
