Horn Lake is right across the state line in Mississippi.

From the 3rd St. exit on I-55, drive 7.8 miles south on 3rd aka Highway 61.

After a few miles you will see Robco Lake to the right - ignore it - that's not where you're headed.

Just past the large sign which reads "Mississippi Welcomes You!", look for another sign on the right which reads "Lakeview Boat Dock" fishing area.

Turn there, and drive about 1/4 mile or so west. Cross the RR tracks, and you will then see the lake below.

The ramp is straight ahead.
