This is my local hiking spot. I take Marengo Ridge for granted, but in reality it's probably the best spot in this part of northern Illinois. It has several different types of trails. Prairie grassed, woods grassed, and about 2 miles of wooded hiking trails. The hiking trails are fairly challenging with a lot of hills and obstacles, and overall a lot of fun. There is plenty of parking, bathrooms, and picnicking areas. There is a paved camping loop with several dozen sites. Overall, this is just a really nice place to have close by.
