Tucked away in Washington County, Great Heath is one of Maine’s most remarkable and least-visited natural areas — a vast, 6,207-acre raised peatland that feels unlike anywhere else in the state. This isn’t your typical state park with marked trails and visitor centers. Great Heath is a wild, open expanse of sphagnum bog, low-growing shrubs, and scattered pitch pines stretching to the horizon, offering a landscape more reminiscent of subarctic tundra than coastal New England.

What makes Great Heath special is its sheer scale and solitude. It’s one of the largest raised bogs on the Eastern Seaboard, and on any given day you’re likely to have it entirely to yourself. Birdwatchers come for palm warblers, Lincoln’s sparrows, and short-eared owls that nest in the open heath. Botanists seek out the carnivorous sundews and pitcher plants scattered among the sphagnum. In autumn, the heath erupts in cranberries and blueberries that have drawn harvesters for generations.

Getting around requires some initiative — expect wet feet and uneven, spongy ground. Waterproof boots are essential. There are no established trails or facilities, so pack everything you need, including water and a GPS or compass. The terrain can be disorienting in fog.

The best time to visit is late summer through early fall, when the berry season peaks and the boggy ground is at its driest. Spring brings nesting birds but also black flies in force.

Great Heath rewards those willing to venture off the beaten path into something genuinely untamed.
