Welcome to your own little slice of Heaven in the heart of Lyons! This is a truly unique and special creek-front property, just steps from all that Lyons has to offer. Step out your front door and you literally have the Lyons trail system at your feet! Step across the bridge and you are in bustling Downtown Lyons to enjoy coffee, meals, brews, and entertainment! Imagine entertaining, creekside, on the flagstone patio with a built-in firepit, beautiful flagstone benches, and the sound of trickling water in the background! A stone staircase brings you directly into the water, where you can enjoy swimming, lounging, fishing, and floating!
