A lovingly designed lavender café nestled between flowering meadows and lavender fields – the farm shop offers good coffee, delicious cakes, soup to recharge your batteries, and lavender merchandise. Perfect for a stopover! (Card payment accepted.)

A very beautiful climb between meadows and picturesque houses, with wonderful views of the Krkonoše throughout. Mostly good to fair road surface.

Great road to ride on. It is rather wide, and most drivers I encountered were friendly when overtaking with a large amount of space between the bike and the car.
