PlyWood Trail
The PlyWood Trail connects Plymouth and Woodbury counties as it travels from Le Mars, through Merrill and Hinton, before finishing in Sioux City. This fully paved trail runs parallel to Hwy 75. As of 2026, the section between Merrill and Hinton is yet to be constructed. This specific route will take you on County Hwy K42 between those two towns. Visit plywoodtrail.org to learn more.
