Lago Negro Lago Negro (Black Lake) is the most known, visited green area of Gramado. It was created in 1953 by Leopoldo Rosenfeld on an area containing a large concentration of hydrangeas, hence the name the
Hydrangeas' Region. It was named Black Lake because Rosenfeld imported the trees surrounding the lake from Germany's Black Forest. This area had been destroyed by fire in 1942. A creek was dammed up to create a U-shaped lake. Rosenfeld imported pine seedlings from the
Black Forest in
Germany to be planted all around the newly formed lake's rim. Lago Negro is a 1.6 kilometers away from the Town Hall. There is a boathouse, working daily from 08:30 to 19:00, where you can rent swan boats to tour the lake, concession stands, public restrooms, and a small craftsmen fair nearby. The city is in a mountain range, averaging 850 meters above sea level. Visitors from the Northern Hemisphere mid-latitudes may notice several tree species (including
red maple,
American sweetgum and
American Tuliptree) common to their home territory in cultivation here, flourishing among the native
Parana Pine.
Hydrangeas blossom in late spring.
