The Marian Valey (Mariánské údolí), located at the eastern edge of Brno, is a popular recreation spot among locals. In summer, it’s used for hiking, biking, running, and swimming. In winter, there’s skating and X-C skiing. There are remains of old castles and settlements, and some caves that visitors like to explore.

There are many km of mainly wooded trails. Some are paved multi-use paths, and others are more single track cycle trails. There eastern part of the park is hillier. A couple of favorite running spots:

Along the Reservoirs. There’s a paved path headed mainly north from the parking lot along a couple of reservoirs. It’s a pretty path, with some nice views. It’s nearly 4 km one-way, and rolling hills! ROUTE MAP

Paths Headed East. A mainly paved path heads east from the parking lot for ~3 km toward Horákov.

Other Paths. Several km of additional paths, mainly wooded.

Note: Some trails in winter might be used for X-C skiing.
