Chuchelský háj, Nature reserve in Prague 5, Czech Republic

Chuchelský háj is a nature reserve on the slope between Velká Chuchle and Malá Chuchle in Prague, protecting original deciduous woodland and a rocky steppe slope below the church of St. John of Nepomuk. Its bedrock mixes diabase, shale, limestone, sandstone and quartzite, and the reserve also contains the Chuchelský cemetery and a forest lodge with a small zoo.

The area was formerly called "Lázeňský háj" (Spa Grove). During the First Republic era there was an excursion restaurant there. The forest is now part of the Radotínsko–Chuchelský háj Nature Park.

Access the reserve via Pod Akáty street in Velká Chuchle or from the Malá Chuchle crossroads, both served by public transport. A marked educational trail with information panels guides visitors through the forest.

The reserve's rocky slope beneath the church of St. John of Nepomuk is the type locality of a newly described iris, the Czech beardless iris, named from the diabase rock. The same rocks support Allium senescens and white stonecrop.
