Illinois Gulch is a slightly rough picturesque trail in the Rainbow Falls area of Colorado. Easy to access yet less crowded than the nearby Flake Road, it's perfect for those looking for a peaceful weekend getaway, complete with numerous well-developed campsites. Illinois Gulch is a gateway to Long Hollow Road and the 15-square-mile Rainbow Falls Trail Network. However, this mild trail becomes significantly more challenging with fresh or ice-packed snow during winter, requiring extra caution. Despite its roughness, Illinois Gulch remains an alluring destination for newbies and seasoned drivers seeking memorable off-roading adventures while camping amidst nature's beauty.
