Fisherman's Corner is a great little C.O.E. campground. We camp there for several days twice a year, on our way out west and on our way back.
Campground MapThe loop to the left of the check-in station has the only sites with a chance of getting some view of the river. Also, the nicest loop, at least we think so. Be sure to make reservations. That loop used to be first come, first serve. Not any more.
There is a nice restraint in Rapids City about 4 miles north of Fishermans Corner on Rt 84, "My Brothers Place".
