Onawa / Blue Lake KOA

Follow the Lewis and Clark Trail to the Onawa/Blue Lake KOA in the heart of the Loess Hills, formations created thousands of years ago when retreating glaciers left behind fine silt particles called loess.

Local Area

Loess Hills

Along the shores of the Missouri river, discover historical natural wonders in the unique and beautiful Loess Hills. Loess means windblown soil. Strong winds 14,000 years ago swept silt deposits from the Missouri River Valley flood plain into huge clouds of dust, depositing them into rugged bluffs which formed the Loess Hills. Monona and Harrison counties, being the widest and deepest areas of loess soil, are considered the "Heart of the Loess Hills." The Loess Hills Scenic By-Ways in western Iowa have been named one of the nations "10 most outstanding scenic by-ways." The By-Ways stretch 220 miles across western Iowa, the full length of the Loess Hills.
