For lovers of prairie, August is an exhilarating month at Frontenac State Park. In the prairie landscapes that grace much of the lower park and part of the upper, native grasses top 6 feet in late summer. On a breezy day, they and robust wildflowers sway in the warm wind, their graceful waves bringing to mind a land ocean. Walking along the mowed paths, you feel like you’re moving through nature’s labyrinth.
