The Cog Railway to Mount Washington is a unique train service that takes passengers to the summit of Mount Washington, the highest peak in the northeastern United States. This railway, which began operation in 1869, uses a cogwheel system to climb steep grades, making it possible to ascend the mountain safely and comfortably. The journey offers stunning views of the surrounding landscape, including the White Mountains and the Presidential Range. The train operates seasonally, typically from late spring to early fall, allowing visitors to experience the beauty of the mountain and its diverse ecosystems.
