Maine is the largest state in New England, and it is the most thinly populated. Vast forests cover much of northern Maine, which definitely lives up to its nickname, the Pine Tree State. But, it is the long, serrated coastline, the famous "stern and rock bound coast," that draws the most visitors. The capital is Augusta, in the center of the state on the Kennebec River; but Maine's cultural and commercial center, chief port, and all around big city is Portland. There are a number of coastal resorts of great character and charm. Ogunquit, on the south coast, is a famous art colony; while nearby Kennebunkport has long been a retreat for artists, writers, and the well to do. Old Orchard Beach boasts one of the longest stretches of sandy beach in the Northeast, and it has a boardwalk that in summer is thronged with French-speaking vacationers from Quebec. Inland lakes, ponds, and rivers draw summer visitors to old resorts like Bridgton, Bethel, Rangeley, and Greenville. In winter, skiers flock to resorts such as Sugarloaf, Saddleback, Big Squaw Mountain, and Sunday River.
