The routes are on average around 2km long with a very few being over 15km. Each route is accompanied with a b/w photograph & a brief history, human & natural, of the immediate area. Nearly all the routes take in the coastline of the Cape Cod area or are within a stone`s-throw of it. Each route is described with the aid of a simple but nice little map so no real need for a separate one. Of the 35 routes, 24 are on the mainl&, 7 explore Martha`s Vinyard, & 4 are on Nantucket. The beginning of the book has a simple road map to show the location of all the routes within the Cape Cod area; whilst the back has a list of environmental organisations.
