DESC: Cape Cod, Martha's Vineyard, Nantucket: The very names conjure images of endless sandy beaches, old whaling towns, lighthouses, cranberry bogs, and sheltered coves. Here, the scenery changes with the seasons -- from colorful wildflowers to fall foliage, from migrating birds to wintering seals -- and this naturalist's hiking guide tells you when and where to see it all. The region includes some of the best bird-watching trails in the Northeast: salt marsh walks, woodland rambles, beach strolls, wildlife refuges, and the magnificent 40-mile-long Cape Cod National Seashore. With a climate tempered by the sea, summers linger into fall and winters are mild enough for year-round hiking. Of the 35 walks described in this updated second edition, 24 are mainland jaunts, 7 explore Martha's Vineyard, and 4 are on Nantucket. Each description includes a map, directions to the trailhead, and commentary on local and natural history.
