Zillergrund is a a 20 km (roughly 12.5 mi.) long valley that is part of the Zillertal Alps in Tyrol, Austria. Shot in 4K with the DJI Mavic Pro, AirVūz Contributor Sennevd1 shows us how beautiful this historic valley can be. With rushing waterfalls and streams, lush forests, and hidden towns, it's a little alpine gem. The Zillerton Alps are a sub-chain of the Alps range which lies primarily within the borders of Austria, with a small portion in northern Italy.
