No matter if you are heading east or west on Interstate 90 the Chamberlain Rest Area Facility is a nice place to stop.
There is a great museum that has a re-creation of the 55 foot keel boat used by Lewis and Clark on their discovery expedition. The museum is open from Mid-May to Mid-September each year.
And, the museum and rest area have sweeping views of the Missouri river valley and Lake Francis Case. Plus, the amazing sculpture Dignity of Earth and Sky is located here. This is an amazing tribute to South Dakota’s rich Native American Culture.
I also enjoy the walking paths. I really like to get out and stretch my legs after I’ve been traveling. Do watch for rattlesnakes though.
There is plenty of parking for cars, trucks and campers. Watch for exits 263 and 265 to enjoy this rest area.
If you are into history, maybe take some time to checkout the Old Highway 16 “double barrel” Bridge. It is a fun way to cross the lake from Chamberlain to Oacoma.
