Shining Sea Bike Path, Falmouth MA
One end of the bike path is in North Falmouth and the other is in Woods Hole. The path follows the old railroad grade so is fairly flat with gradual rises. It is for bicycles, running, roller blades, and walking.
It passes by salt marshes and beaches while traveling through some woods. The views along the path are to the west so the sunset over the salt marshes can be amazing.
There are a number of ice cream shops along the way as well as a few restaurants. Parking lots are at both ends and a few along the way. On weekends during the summer thousands of people use the path during the day, but in early evening the numbers have thinned out. Fall is a great time to see the foliage and relatively few people on the path.
