Recommend Army Corp of Engineer campground on the south shore of Lake Wilson Kansas. Just 7 miles off I70 and great sites with views of lake.
About 2 exits east of the Junction City, KS exit on I-70 is highway 177. Go south on 177 about 25 miles to the Council Grove, KS ACOE Campgrounds. There are 3 entrances off 177; Richey Cove, Kit Carson Cove Park and Kansa View Park.Have lunch or dinner at Hays House, downtown Council Grove. As best I know, there are over 20 historic landmarks in that little town. Very quaint and we liked it a lot.You'd be smart to Google better directions.Enjoy your adventure and be safe (there are a lot of crazies on the roads).
A big on both the recommendations above in Kansas. Been to both of them. Wilson lake is beautiful. Council Grove is in the Tallgrass area of the state. Lots of old west history there, and the COE reservoir is a good place to stop. Excellent laundromat there in town if needed.Hays Kansas is a nice small college town to check out the downtown area. Victoria Kansas has a beautiful cathedral just off of I70 to check out.
