The river Sázava rises in the womb of the mountain forests of the Žďár Hills on the European watershed between Herálec and Vojnový Městec. You can't really get here by bike. The Sázava cycling route No. 19 starts in Lísek near Bystřice n. Pernštejn, where it connects to the Prague cycling route No. 1. But we will visit this part on a trip on EV4. So the route starts at Nám. Republic in Žďár n. S., where the river meets the cycle route and which is also the highest point according to the altitude of the whole journey. We leave the Žďár center by Nádražní and Tyršova streets, which lead us to the cycling route along the Sázava River. With the help of signs, we cycle through cycle route along Brodská Street in the direction to Hamry. We go through the whole village to the pension Najdek, where we cross the river and the first part of the ride on the asphalt road through the woods up to the river Sázava begins. We will see the Brdíček's Mill across the river, which we will visit as part of the trip No. 16, and when we turn to the Evangelical Church in the village, we meet a little further elephant sculpture by M. Olšiak. At the lower end of the Sázava, we can expect a great 10 km on a cycle path set up on the railway body of the former railway. It will lead us to Přibyslav. Another section of the valley was occupied by the railroad and busy road No. 19, which is dangerous for bikers, and therefore we will climb for the first time from the river to the hills. Through Utín, Dlouhá Ves and Bartoušov we set off to Havlíčkův Brod, the largest city on our route. Luckily, busy Brod has cycle routes on the river bank, which we use for smooth ride through the city. Exit in the direction of Humpolec and again leave the company of the river and cross the hills in the direction of region of Jan Zrzavý. Through Poděbaby, Hurtova Lhota, Březinka and Vadín we are in Okrouhlice, the birthplace of the famous painter Jan Zrzavý. We take ride throzgh the picturesque region of the Sázava River, and although the cycling route no. 19 is high up to Lipnice nad Sázavou, follow Babice along route 4155 and we will prefer a small sight with a new open-air museum on Michal's farm. Access by road through Příseka to Světlá n. Sáz. takes us under the chateau weir again on Route 19. We leave the historical center of Světlá, packed with tourist attractions, again on the waterfront cycle route. It changes with the road and again with the cycle path, until it reaches the border of the famous Stvořidla River section in the forest valley near Smrčná. The plan for making Stvořidla and Sluneční zátoka accessible by cycle route, which would connect Světlá with Ledčí, is still on the ice, and even fierce bikers do not recommend to run along the section of the river, which still serves only for hikers. There is no other way from Smrčná than to climb to the heights of the mountain Melechov and to traverse the Sázava valley 100 meters higher. On the way through Koňkovice, Trpišovice, Bilantova and Dobrovítova Lhota we have views of the wider surroundings of the wooded valley. Only near the village of Bojiště resembling the Hussite battle of Melechov we descend to the bay of Sázava, where Ledeč Castle and its town is settled. In Ledeč, the Sázava rises from the grip of the hills of Vysočina and begins to carry boaters on its back. However, in the twisting valley, there was again a place for the Posázavský pacific, so at the ruins of the castle Chřenovice we againh climb from the river, this time above its right bank. The forest asphalt road takes us to Jedlá, from where it is close to Tasice, where is glass museum. From Jedlá, the road runs back to the river to Vlastějovice. And we are already in the Central Bohemian Region and within sight of Zruče n. Sáz., our final destination.
