Geography of Maine

Maine's geography is built around two dominant facts: an enormous, deeply indented coastline and a vast forested interior that makes it the largest and, outside its southern corridor, one of the most sparsely populated states in the East.

The Coast

Maine's coastline stretches for roughly 3,500 miles when every bay, peninsula, and island inlet is measured — longer than California's coastline despite Maine's far smaller size, a direct result of how fragmented and bay-cut the shoreline is compared to a straighter Pacific coast.

The Forest Interior

North of the Portland-Augusta-Bangor corridor, most of Maine is forested and lightly settled, dominated by working timberland, lakes, and long distances between towns — a landscape closer to parts of Canada than to the rest of New England.

Mountains and Highlands

Western and north-central Maine hold the state's highest terrain, anchored by Katahdin and the Bigelow Range, part of the broader Appalachian system that shapes the region's weather, hiking culture, and seasonal recreation.

Lakes and Rivers

Moosehead Lake, Maine's largest, along with Sebago Lake and the Rangeley Lakes chain, anchor the state's inland recreation, while major rivers including the Penobscot and Kennebec have shaped settlement and industry since the colonial era.

Aroostook County

In the far north, Aroostook County alone is larger in land area than Connecticut and Rhode Island combined, yet holds only a small fraction of their population — a scale mismatch that captures just how empty Maine's northern interior really is compared to its coastal image.

Human Geography

Population concentrates heavily in the south and along select coastal stretches, while the north remains genuinely rural — a divide that shapes everything from politics to school access to healthcare delivery across the state.
