Riders, get in gear: this ten-mile path runs from Woods Hole to North Falmouth, and passes through some of the most picturesque beachfront, cranberry bogs, salt marshes, and historic farmland on Cape Cod. (The trail was originally part of the Plymouth and Vineyard South Railroad.) With lots of twists and turns but not many hills, it̢۪s an ideal afternoon trip for younger bikers. And don̢۪t be put off by the length: Many families simply ride the first few miles from North Falmouth and then loop back, or start in Woods Hole in the morning and then return to town in time for lunch.
