About this swimming hole

A Kancamagus Highway favorite where the Swift River slides over smooth rock into swimmable pools, with restrooms and picnic tables at the roadside stop. The granite slabs are perfect for spreading a towel, and the water runs clear and cold. It is one of the easiest classic swims in the Whites.
