Hotel - Landgasthof - Restaurant | Rössle Oberprechtal - Elzach | Home. Since 1914, we know how to pamper our guests. Ernest Hemingway appreciated the Black Forest trout in the young Elz and felt at home in our establishment in 1922. The traditional Black Forest house was built in 1914 and lovingly renovated and expanded by us in 2000. We warmly welcome you! Your Family Vogt.
