This lake is so wonderful. Take a trip to nearby Fallen Oaks Equestrian Center and ride a horse, and obviously, everyone loves Chain O'Lakes State Park. A beautiful lake like Round Lake next to Highland Lake is a magnificent place to explore. For all you boaters, Chain O Lakes Marina & Ships is a wonderful marina in the neighborhood; if you like skiing, you're in luck; Wilmot mountain is relatively near.
Fox River Recreation is a glorious campground nearby, and you're sure to encounter some great people from Round Lake here. So many cool things near Highland Lake, clearly mind-blowing.
