The Wachau Valley has been a UNESCO world heritage site since 2000, and it is an area known for its wine, landscape and medieval towns. Tiered vineyards line the green hillsides, where history melds into the landscape in picturesque villages. You know you’ve arrived in the Wauchau when you pass by the southern riverbank and the dramatic, baroque Melk Abbey sits nearby. The Danube River is serene, widening at some areas and narrower at others, and accented by lush forests close to the water’s edge, due to the fertile river soil.
