We did a house swap to Bernartice in Southern Bohemia. The roads are fantastic for cycling and our hosts had left us two good bikes. We set off cycling to Zvikov (round trip 20 miles), unsure of what we would find at journey's end. We were stunned by the beauty of Zvitov, set as it is at the confluence of the Vlatava and the Otava, a magnificent gorge and has a beautiful 15th century castle. You can do boat trips from the little jetty. Very understated.
