Lake Ottawa
Clear national forest lake with a sandy swimming beach.
MoreA deep, cold, clear lake with a sandy bottom, about five miles southwest of Iron River. The beach and picnic grounds sit in the Lake Ottawa Recreation Area, with a boat ramp and a fishing platform. Day use is $5 a car or $30 a season, mid-May to mid-October. The old log pavilion is closed for repairs in 2026, so don't count on changing rooms. Lake trout, pike, walleye and panfish, and every bass goes back. A national forest campground sits next door.
