We never made it to Icelandic SP, but did do a few times at Lake Metigoshe State Park which is on the border with Canada about 10 miles north of Bottineau, ND. A very nice campgound in the woods (hard to find in ND at times) and up in some hills called the Turtle Mts. All very pretty, nice lake with bike/hiking trail, boating, fishing.
It was not far from the International Peace Garden on the U.S. and Canadian border.

We did an overnight at Turtle River State Park, located 22 miles west of Grand Forks on Highway 2.

Just off US 83,
The North Dakota Lewis & Clark Interpretive Center between Bismarck & Minot at Washburn. Not sure about overnighting, but neat to visit, nice place to take a break. Pretty vista.
Not far from Washburn, the
Knife River Indian Villages Nat'l Historic Site was very interesting.
We found the
Scandinavian Heritage Center and Park in Minot was neat to see.
Also between Minot & Bismarck,
Lake Sakakawea State Park with links to other sites. Also in the area,
Cross Ranch State Park. We have not been to them, but my son has.
