The Swift River rises in the township of Livermore, New Hampshire, on the eastern side of Kancamagus Pass, and flows east into a broad valley, surrounded by mountains, known as the Albany Intervale. Leaving the intervale, the river enters a narrow gorge, passing over two sets of small waterfalls, and continues east through the town of Albany to the Saco River at Conway.

The river is paralleled for its entire length by New Hampshire Route 112, the scenic Kancamagus Highway.
