Horseshoe is a great campground if you want to be close to the water. It sits on a peninsula so pretty much no matter what site you have you will see the water. It's like many other Corp of Engineer parks: vault toilets, minimal shower houses.  

The nice:

• Great hosts;
• Most sites have a flat gravel squared off area for a tent. In our case we put our canopy there for our cooking station.
• You are right beside or at least see the water from most sites;

The not so good:

• crowded;
• some sites are cramped on space;

We were in site 126 and liked it. I do quite a bit of homework before I pick a site.  My biggest advice would be to pay attention to the map.  The two larger site areas tend to be very crowded. 

There was a short but nice trail.  There was a swimming beach that had sand versus the normal rocks!  Also, deer were very used to campers.  They didn't come into campsites but had no issue grazing on the edge of the woods near the roads.

Overall good enough that I want to go back.
