Baba, Natural monument in Hluboká nad Vltavou, Czech Republic.

Baba is a natural monument in Hluboká nad Vltavou featuring geological formations and diverse plant species along the Vltava River bank. The site reaches about 449 meters in elevation and displays various rock layers and structures that shape the river valley.

The Ministry of Culture of the Czech Republic designated Baba as a protected natural monument on May 1, 1989, establishing formal conservation measures. This recognition marked the beginning of systematic efforts to preserve this geologically significant area.

The name Baba refers to the hilltop, where remnants of a Bronze Age hillfort sit at 435–449 m; the Czech geologist Jan Nepomuk Woldřich first published a mention of the hillfort in 1883. Most of the protected area lies within the Stará obora game reserve, and the site is also a Natura 2000 site and part of the Hlubocké obory bird area.

The site is accessible year-round without entrance fees and features marked paths leading through the protected area. Visitors should wear sturdy footwear as the terrain can be uneven and some paths may be steep.

The bedrock is biotite-muscovite granite containing tourmaline, shaped by river erosion and periglacial weathering into crags and small scree fields. On this site the four-spotted click beetle (Ampedus quadrisignatus) was recorded in Bohemia for the first time.
