Arboretum Křtiny, University arboretum in South Moravian Region, Czech Republic.

Arboretum Křtiny covers 23 hectares at 450–500 m elevation between Křtiny and Jedovnice. It holds about 1,000 woody plant taxa, including over 200 willow hybrids and cultivars, plus a pond, peat bog and heathland. Three themed tour routes each take about an hour; wooden sculptures by Mendel University students stand along them.

The site was established in 1928 by Professor August Bayer as a research and teaching facility for Mendel University in Brno. Since its founding, it has grown into the country's leading university arboretum.

The arboretum's three themed educational trails each take about an hour to walk, and wooden sculptures and groups of figures made by students of Mendel University's Faculty of Forestry and Wood Technology during sculpture symposia stand along them. A few dozen metres away lies the Bayerova nature reserve with a memorial to August Bayer.

The grounds are open from May through October and offer guided tours for groups that need advance notice before arrival. Leashed pets are welcome, and multiple paths allow you to explore the site at your own pace.

The rarest tree here is the Japanese umbrella pine (Sciadopitys verticillata), brought from Japan. Nearby stands the Bayerova nature reserve with a memorial to August Bayer, a few dozen metres from the arboretum grounds.
