About this swimming hole

A local-favorite rope swing hangs over a deep turquoise pool on the Mad River near Kneeland, reached via Hatchery Road off Highway 299. The water glows an almost tropical green-blue in summer, a striking contrast to the surrounding redwood country. It is a long drive from anywhere, which keeps the crowds thin even at peak season.
