Northeast of Prague and and north of Vrchlabi on the Polish border, the Spindleruv Mlyn Ski Area is a Soviet-era block style ski resort that has lift-accessed mountain bike trails.
There are several downhill specific mountain bike routes on Svaty Petr. The Black Trail is 2.1km and descends 450m. It begins at the tower next to the upper station of the Pláň chair lift. The trail follows the chair lift line right under the chairs. It is very technically demanding with difficult parts that can be managed only by experienced cyclists. Its characteristics comply with all the requirements for both national and international races. There are both natural and artificial jumps, short wooden bridges and its surface consists of clay, stones, forest soil with roots, as well as of small stones. The Red Trail is 2.8km and descends 450m. It begins at the tower next to the upper station of the Pláň chair lift. It follows the blue downhill trail with frequent turnoffs leading into the surrounding forest. It is less technically difficult with rather a free-ride character and it is suitable for a wider range of cyclists. There are a number of slopes, clay and wooden jumps, wooden bridges, and many sections of its surface are gravelled for a smoother and more pleasant ride. The Blue Trail is 7km and descends 430m. It starts in the proximity of the upper station of the Pláň chair lift. It runs on gravel and asphalt paths and the lower part of the trail runs on a concrete panel road. It is a pleasant, scenic ride for complete beginners and for families with small children who can handle a bike well. The shorter Stump Trail is only 500m and leads from the upper station called Hromovka. It is a trail designed rather for more advanced and experienced cyclists who can fully enjoy themselves on profesionally created bridges with a number of jumps, slopes, artificial waves and other challenges for bikers. You can join the trail from the existing downhill mountain-bike trail close to the upper station of the Hromovka chair lift. After half a kilometre, the Stump Trail rejoins the original downhill trail again and continues on to Svatý Petr. All the trails are marked with arrow signs in the colour of the relevant trail. We recommend you to go on the black and red trails only with an integral helmet and protective pads; on the blue trail it is sufficient to use an ordinary bike helmet.
Overall, Spindleruv Mlyn Bike Park is the 5th most popular mountain bike trail of all 5 mountain biking rides in Czech Republic.
