Roskilde Fjord and Isefjord Through the Green along the Blue is a 171-kilometre-long route along Roskilde Fjord and Isefjord. No need to cycle all 275 kilometres – at least not in one go. Planning a route that includes both ferries and bridges is easy. A brief introduction to the many experiences on the Fjord Trail starting in Hundested and ending in Rørvig Harbour can be found below.
