Great place for RV camping. My Uncle and I went through here back in 2011. All sites were reservable on-line. Every site had electric hookups. There is access to water and restrooms in each loop. Some of the sites are right near Lake Yankton. There was decent fishing but nothing too special. The park itself is very close to South Dakota, and you can visit the old time capitol of the Dakota Territory. I love the little history pieces like this so it was worth the side trip for me. It is also right near Lewis and Clark Lake which has really good fishing in the early morning. People we met were using the spot as they were passing through the area or for taking kids out for the weekend. Pets were allowed here too.
