Cowley County State Fishing Lake, east of Arkansas City, Kansas on highway 166 – As one would expect, Kansas doesn’t have a wealth of grand waterfalls, but it does have a few. Located in the southern reaches of the Flint Hills, Cowley County Fishing Lake has a beauty that drops 30 feet across colorful layers of red shale. It’s a difficult climb to the bottom, but it’s a nice place to be on a warm day, in the water spray at the base of the falls, where the steam spills over fossil-embossed limestone boulders. These falls are best viewed in the spring rainy season.
