The instructional trail Klokočín leads in the surroundings of the Klokočín fortress about 5 km north-west of the town Protivín.

The trail acquaints visitors with nature of this region - primarily with dendrology, ornithology, and botany. Most of the information is about trees of South Bohemia, partly about rare or otherwise interesting plants.
