Blue Mounds State Park campground is located on tree-lined paved roads tucked in between a prairie and farmers' fields. It's quite peaceful and relaxing, especially with most sites unoccupied during the week.
While the sites don't offer a ton of privacy, they are well-spaced for the most part and some of the loops have foliage behind the sites so you have a bit of a buffer there. The loop we were in (on site 28) has a relatively new bathroom and shower house that is very nice. The other loop has the older-style bathroom and shower house that looked clean but is showing its age.
Even though you probably could rely on your cell phones here due to good and great signals (Verizon and T-Mobile respectively), the campground also offers WiFi that is actually quite good. The transmitter for our loop is on the bathroom building and we have been able to work, including video calls, all week without any issues.
The sites themselves have gravel pads and decent-sized grassy areas to set up screen tents, etc. The park itself offers several things to do, including watching for the protected bison herd out on the prairie, as well as hiking and biking trails that can lead you to a historic quartzite quarry and some great vistas of the area around you. At night, it's nice and dark so you can see a lot of stars -- if you walk a short way down one of the trails from the campground you can even see the Milky Way.
If we are in this area again, Blue Mounds would certainly be a place where we would check for openings.
