The 200 ft. high Arethusa Falls area includes Bemis Brook and Coliseum Falls. They are located on a one-mile path south of Willey House site off Rt. 302 in Crawford Notch, New Hampshire. The falls are an easy 5-mile hike in, while Arethusa is 1.3 miles in on a hike of moderate difficulty.

Arethusa is best viewed from below. Refrain from rock scrambling if you value your health: those rocks are unsafe. If you wish to swim, choose spots downstream.
