Cape Cod isn’t connected by land to the mainland, but it’s not exactly an island, or at least wasn’t until the Cape Cod Canal was dug in 1914. The 7-mile-long canal saves ships from having to sail an extra 135 miles around the treacherous tip of the Cape. The canal is also a great recreational resource bordered on both sides by trails that attract cyclists, in-line skaters, power walkers and freckle-faced kids with fishing poles. On a sunny day it looks like a scene from a Norman Rockwell painting! For the scoop on the how, what and why of the canal, stop by the Cape Cod Canal Visitor Center , near the Sandwich Marina, where interactive exhibits will capture the interest of kids. Follow your visit with a 10-minute walk along the canal to the beach – unlike at other beaches, car parking here is free. Ask at the center about its free programs offered throughout the summer, including guided hikes and bike rides, beach walks and talks.
