Fuldaaue, Recreation area near Fulda River in Kassel, Germany

Fuldaaue is a recreation area stretching along the Fulda River in Kassel with wide paths for cycling and walking, open meadows, and swimming spots. The site also features a children's playground and plenty of green spaces for relaxation.

The Fuldaaue was laid out at the end of the 1970s as an inner-city park on the eastern bank of the Fulda for the 1981 Bundesgartenschau, which is why locals call the grounds Buga. The central Buga lake began as a gravel pit dug in the 1960s that later filled with groundwater, and the surrounding grounds and bathing beaches were completed in 1980.

Locals call the park Buga after the 1981 Bundesgartenschau, the federal garden show it was built for. The artificial lake is nicknamed Bugasee, and its beaches serve as a swimming spot in summer. Anglers and the Kassel drainage authority work to keep the meadows near their natural state.

The Fuldaaue lies in the Waldau district, bounded by the Fulda's east bank and the Damaschkestraße to the south; two footbridges over the river link it to the Karlsaue. The northern part of the Buga lake is a nature reserve for waterbirds, so bathers should keep to the beaches and marked areas. The site also serves as a floodplain, so parts can be wet after high water.

The northern part of the Buga lake is a designated nature reserve, created to secure a breeding, resting and wintering ground for numerous waterbird species, some of them endangered. The whole Fuldaaue also belongs to the EU bird protection area around Kassel, which reaches south into the Kassel district and the Schwalm-Eder district.
