Průhonice Park sits roughly 12 kilometres south-east of central Prague, beyond the edge of the city in the Průhonice municipality of the Prague-West District. It covers 247 hectares and functions simultaneously as a public recreational park, a dendrological scientific garden, and the grounds of a working research institute. Those three roles do not always sit quietly alongside each other, but the tension between them is part of what makes Průhonice one of the more interesting botanical landscapes in Central Europe.
How the Park Came to Exist
The park in its current form was shaped almost entirely by one person: Count Arnošt Emanuel Silva-Tarouca, who acquired the Průhonice estate in 1885. Silva-Tarouca was not a gardener in the decorative sense. He was a serious plant collector who had studied the estates of Western Europe and wanted to create something that would demonstrate what Central European climate and soil could actually sustain.
Over the following four decades he introduced more than 1,600 taxa of woody plants to the grounds, working systematically through the valleys carved by the Botič river and its tributary streams. The topography of the site — shallow ridges, valley floors prone to frost, south-facing slopes warmer than the surrounding plateau — gave him a range of microclimates that made it possible to grow species that would have struggled on flat ground.
After Silva-Tarouca’s death, the estate passed through various institutional hands before becoming the seat of the Institute of Botany of the Czechoslovak Academy of Sciences. Today it operates under the Czech Academy of Sciences, and the dendrological garden within the park is formally a protected landscape monument.
Silva-Tarouca’s method was to plant densely and thin aggressively over decades — he understood that a landscape park requires generations of adjustment, not a single design moment.
What the Park Actually Contains
The 247 hectares divide roughly into three zones. The area immediately around Průhonice Castle (a neo-Gothic reconstruction with 12th-century foundations) holds the most formally designed sections, with large specimen trees, a pond system fed by the Botič, and cleared meadow areas managed to maintain views across the valley. This part of the park is the one most visitors see.
Further into the grounds, the planting becomes denser and more specifically botanical. The dendrological garden section, covering approximately 85 hectares, holds the systematic woody plant collection organised roughly by geographic origin. North American maples, Asian magnolias, and European native tree species occupy different areas, though the groupings are not museum-like — plants have grown into each other over the decades and the collection feels more like a mature forest than a catalogue.
The third zone, less accessible, consists of managed natural habitats: old-growth sections, wetland margins around the upper pond, and grassland maintained by traditional cutting schedules. These areas support populations of plant species that have become rare in agricultural Czech landscapes.

Rhododendrons and Seasonal Highlights
The park is best known outside the botanical community for its rhododendron collection, which was assembled by Silva-Tarouca with particular thoroughness. The collection includes both species rhododendrons and a significant number of hybrids, many of them developed at Průhonice itself. Peak flowering runs from late April through mid-June depending on the year and the specific cultivars, with late May usually producing the densest colour.
Outside the rhododendron season, the park has different draws. Early spring brings snowdrops and hellebores in the shadier sections. Summer sees the meadow areas at their most open and the ponds active with waterbirds. Autumn produces reliable colour from the North American maples and the liquidambar specimens near the castle. Winter visits are quiet but the structure of the mature tree planting is clear without foliage.

The Research Institute and the Botanical Garden
The Institute of Botany of the Czech Academy of Sciences occupies the castle building and associated structures. The institute runs the dendrological garden as a scientific collection, meaning that some areas are managed with research priorities that override visitor access. Restricted sections exist, and the signage in these areas is minimal.
The botanical garden within the park — distinct from the wider dendrological collection — covers about 21 hectares and holds a more formally documented collection with labelling by species and origin. This section hosts events including the annual dahlia exhibition in September and an iris sale in summer when surplus rhizomes from the collection are made available to visitors.
The Průhonice website (pruhonickypark.cz) maintains accurate current information on events, temporary closures and seasonal programs.
Getting There and Practical Details
From Prague, the most straightforward route uses the metro to Opatov (line C) followed by bus routes 363 or 385 towards Průhonice — the journey from the metro station takes around 20 minutes and deposits visitors at the main entrance near the castle. By car, the park is reached via the D1 motorway with exit at Průhonice; parking is available on-site but fills quickly during rhododendron season.
The park charges entrance fees varying by season. Spring rates are higher than the off-season price. The dendrological garden section carries a separate entrance fee from the wider park. Children under a certain age enter free; confirm current thresholds at the ticket office as these change.
Opening hours vary across the year, with the park accessible daily but closing earlier in winter months. The castle itself is not part of the visitor circuit — it remains an active research building.
