A fun ride across the fens - much easier if there isn't too much wind. Going through Outwell and Friday Bridge rather than Emneth and Elm avoids some rough roads, but still contains several more-than-a-mile straights (pictured). There are shops at each end and in the bigger villages.  There is a pretty good cafe for lunch called Panini's in March Town Hall. Easiest bike parking (pictured) is in the middle of Broad Street, before you reach it.
