Jump into summer as you swim in Centennial Beach’s historic stone quarry. It’s not a swimming pool, it’s not a lake, but a swimming experience like no other! Wade into the zero-depth entry and swim to depths of 15 feet. For generations, Centennial Beach has been the local “swimming hole” for many Naperville residents and their guests. It’s a great place to meet friends, gather with family, or simply relax and enjoy.
