Great weekend spot!
Chester Woods is a county park just east of Rochester, MN. It has a campground and man-made lake (created when Bear Creek was dammed for a flood control project) with hiking trails, a horse trail, picnic shelters, a beach, and a playground. The campsites have nice, soft ground for tents, and electrical outlets are available. It can get noisy on the weekend, but the sites are nice along the edge of the campground.
The lake offers the opportunity to fish for panfish, catfish, and bass. There are a lot of submerged trees from before the Creek was dammed that provide good habitat in deep water, and there is also good shoreline structure and weed beds. There is a fish cleaning house next to the campground which has electric lighting, but no running water.
