One of the main points of interest in Lewis State Forest is the "Old State Road," a historic trail that dates back to the early 1800s. This trail was once a major transportation route in Illinois and was used by pioneers, farmers, and traders to move goods and supplies across the state.

One interesting fact about the forest is that it was once the site of the Eureka College Experimental Farm, which was established in the early 1900s by the college's founder, Christian Church leader and former US President Ronald Reagan. Today, visitors can explore the site and learn about its agricultural history.

The best time of year to visit Lewis State Forest is during the spring and fall, when the weather is mild and the foliage is at its most vibrant. The forest is open year-round, but some areas may be closed during the winter months due to snow and ice.

Overall, Lewis State Forest offers a unique blend of natural beauty, historical significance, and recreational opportunities, making it a great destination for outdoor enthusiasts and history buffs alike.
