Start your bike tour in Prague, and leave the hustle and bustle of the city behind as you head southwest toward the town of Karlstejn, home to the Gothic castle of the same name. Suitable for cyclist of all abilities, the pleasant 18-mile (30 km) cycle will last approx. 4.5 hours and will take you through the flat, yet scenic countryside of the Cesky Kras area, along the Vltava and Berounka rivers.
On arrival in the village of Karlstejn, hop off your bike and re-fuel with a hearty Czech lunch (own expense) before venturing on to the famous Czech castle. Karlstejn Castle has a history of more than 650 years and houses an impressive collection of treasures from the Roman Empire, as well as a gallery featuring portraits of famous Czech rulers. During your one-hour guided tour, learn about King Charles IV's life in the castle and admire the majestic Gothic architecture.
You will return to Prague by train, where your tour will end in the early evening.
