We're taking the week of 4th of July to hike. Starting in South Dakota Badlands then headed towards the North Dakota Badlands. Everyone keeps saying how gorgeous Custer State Park is so we'd probably like to stay there in between. We'd be there probably Tues-Wed July 2-3. The park looks HUGE with many, many campgrounds but do you guys think I need to make reservations because of the holiday? Also then we'd be headed to N. Dakota Badlands on the 4th, 5th, leaving to come back home (Minneapolis) on Saturday the 6th. If we stay IN the park there are no reservations (but no showers :) but if we decided to try and stay in Medora (for amenities) should I make reservations? I've heard the Blue Bell and French Creek campgrounds in Custer are beautiful so that's my goal there - any advice appreciated!
