Sweden
For a bike ride with a difference try cycling along a former railway line - literally. You pedal trolleys which hook onto the rails and lift them off when someone's coming in the other direction to allow them to pass! The trolleys make an authentic clickety-clack noise as they rattle over the joints in the rails and take a passenger, sidecar-style. Great family fun and impossible to get lost.
