About Whitebreast Beach
Whitebreast Beach is a U.S. Army Corps of Engineers-managed swim beach and swimming hole on the south shore of Lake Red Rock, Iowa's largest lake and a huge lake to swim in, near Knoxville. It is part of the larger Whitebreast Recreation Area, which also includes a 132-site campground, boat ramp, and picnic shelters.
The beach sits on Lake Red Rock, a large USACE reservoir on the Des Moines River, surrounded by wooded hiking trails and with cliff faces visible across the water. The lake is known for wildlife viewing, including American White Pelicans and bald eagles in winter months.
Swimming at Whitebreast Beach
Swimming is at a designated, sandy USACE beach with shallow water and a gentle slope, making it naturally suited to families and children. The lake bottom is soft and can be slimy or rocky/clay in spots depending on water level, so water shoes are recommended. Water quality is monitored regularly for bacteria.
How to get to this swimming hole
The beach and recreation area are located at 971 Highway S-71 (also referenced as 971 Co Hwy S71), Knoxville, Iowa, about 10-15 minutes from both Pella and Knoxville.
Parking: On-site parking at the beach; reported to fill up by mid-morning on peak summer weekends, so arriving before 10 AM is recommended.
The hike in
- To the water
- 0 mi (drive-up beach with adjacent parking lot; under a 2-minute walk from car to sand)
No hike is needed to reach the swimming area. Paved multi-use trail segments trace the lakeshore and link day-use areas near Whitebreast Recreation Area, and the 15-mile paved Volksweg Trail runs from Pella west to the Des Moines River/Cordova Recreation Area, but these are optional biking/walking routes separate from beach access, not required to reach the water.
Several miles of hiking/biking trails exist in the broader Whitebreast/Lake Red Rock area for visitors who want a hike in addition to swimming, but none are required to reach the designated swim beach.

What regulars say
Visitors report that weekdays are noticeably quieter than weekends, and visiting just after a holiday weekend can mean having large sections of the park nearly to yourself; early mornings are recommended for hiking the surrounding trails, late afternoons for swimming once the water has warmed, and evenings for sunset views; bug activity was reported as low compared to other Iowa lake spots; one visitor nearly slipped on clay mud near the shoreline during low-water conditions, reinforcing the water-shoes recommendation.
