Azalea and Rhododendron Park Kromlau, Botanical park in Gablenz, Germany

Azalea and Rhododendron Park Kromlau is a landscaped park in Kromlau, Gablenz, with a dirt and reddish-brown gravel path winding between low vegetation, yellow flowers, and a large shrub of pink, purple, and magenta blossoms. The path leads under a canopy of green trees. The park covers around 200 hectares and is considered Germany's largest outdoor rhododendron collection.

Friedrich Hermann Rötschke acquired the Kromlau estate in 1842 and from 1844 gave over almost half his land to a landscape park, planting native and foreign trees and shrubs and hauling basalt from quarries in Saxon Switzerland and Bohemia. In 1875 he traded the estate away; it passed through seven owners in fourteen years until Count von und zu Egloffstein-Arklitten bought it in 1889. From 1893 the garden inspector Georg Eichler tended the park and began planting rhododendrons and hardy azaleas on a large scale. After 1945 it became public property and was declared a nature reserve in 1948.

The stone arch known locally as the Devil's Bridge dates back to the mid-1800s and forms a half-circle over the lake below. On calm days, the reflection completes the circle in the water.

Access to the grounds is free all year, and visitors can explore the paths on foot. There is a pay parking area near the entrance for cars.

The timber guesthouse built in Swiss country style during the 1860s still stands in the grounds today. It shows wooden beams and decorative details that were popular in the region at the time.
