We want to bring our kids (ages 10, 8 and 4) to the UP to see some of the sites and are trying to decide where to camp. Although we want to drive around to see some sites, we love laying on the beach and swimming. We read that the water at Brimley State Park is swimmable but we don't know if this means that it is barely tolerable or if it is warm like Lake Michigan. We've also heard good reviews about Indian Lake State Park. Does anyone have any comments about either of these parks and which ones offer the most comfortable beach?
