The Hostivař Reservoir covers an area of approximately 42 hectares.
The Botič Stream, which feeds the reservoir, is the longest stream in Prague.
The park was officially designated as a nature park to preserve the valley's distinct ecosystem and geomorphological features.
The dam embankment is a concrete structure that separates the lake from the lower Botič valley.
Remnants of the historic village of Záběhlice are located near the western edge of the park.
Nature Park Hostivař-Záběhlice is a protected landscape area centered around the Hostivař Reservoir, the largest body of water in Prague. The reservoir was created in the 1960s by damming the Botič Stream to provide flood control and recreational utility. The park encompasses extensive forested slopes, meadows, and the meanders of the Botič stream valley. Visitors can utilize a designated beach area, rent paddleboats, or play beach volleyball during the warmer months. A network of marked hiking and cycling trails connects the reservoir to the surrounding Záběhlice and Petrovice districts. The terrain includes a mix of paved paths near the dam and unpaved forest trails throughout the valley. The park serves as a local habitat for diverse bird species and aquatic life. It functions primarily as a suburban recreational site for walking, jogging, and swimming.
The elevated path on the dam crest provides a panoramic view of the entire reservoir surface.
Bring a change of clothes if you plan on using the paddleboat rentals.
Stick to the marked trails to avoid the muddier patches found in the valley floor during spring.
Check the local water quality reports posted at the beach entrance before swimming in the summer.
Do not attempt to swim in the areas of the reservoir near the dam wall or technical infrastructure.
Beach and water sports facilities are seasonal, typically operating from late spring through early autumn.
No motorized vehicles allowed on internal forest paths; keep dogs on a leash in designated swimming areas.
