The City of Knoxville is located less than 4 miles from Lake Red Rock, the largest lake in the State of Iowa. Lake Red Rock is a major recreation destination for walking and biking trails, hiking, fishing, swimming, kayaking and hunting. Lake Red Rock is surrounded by state parks which include campsites, interpretive programs and access to a paved 13-mile hiking/biking trail.
Lake Red Rock is also home to white pelicans which migrate through the lake area every spring and fall, and bald eagles can also be spotted during winter months.
