Gysenbergpark, Recreation park in Herne, Germany

Gysenbergpark is a 31-hectare Revierpark in Herne's Sodingen district, opened in 1970 as the first park of its kind in the Ruhr. Its main east-west path follows the former connecting railway of the Mont Cenis and Constantin 4/5/11 mines. The grounds hold the Lago leisure pool, an ice rink, a petting zoo, and the 300-metre children's railway Jolante.

The park was created in the 1970s as part of a network of leisure areas built across the Ruhr region to serve the local industrial workforce. Over the years its facilities grew, and the bathing complex that later became LAGO was added to the site.

The park's name comes from the Gysenberg hill on whose northern slope it lies. Its petting zoo, set in farm-style buildings in the Ostbachtal, keeps Central European livestock breeds and traces its history to 1934, long before the park opened. The children's railway Jolante, running on 600 mm gauge since 1970, passes the zoo and the historic mill ponds.

The main path runs east–west along the former Mont Cenis and Constantin 4/5/11 mine railway line, linking the west side with the ice rink hall to the east side with the Lago pool. Trams 321, 323, 324 and NE32 of the Herner Straßenbahn serve the park. The Jolante children's railway runs all year on about 300 metres of 600 mm track past the animal park and the historic mill ponds.

The Kindereisenbahn Jolante, a 600 mm narrow-gauge park railway with about 300 metres of track, has run since the park opened in 1970. An electric locomotive styled as a steam engine usually pulls three carriages past the animal park and the historic mill ponds in the Ostbachtal, and it operates all year round.
