Blue Mounds State Park is a great campground.  I love the area all the trees.  They have hike in campsites, bike in campsites and regular campsites.  They also have a group area.  If you are in a tent you will have great luck, I would advise in a trailer or Motor Home to inspect you site closely before you say yest to it, or you may be like us and change it 3 times.  Not very many level sites unless you can get up on the tent pad.  At one we thought was fairly level our tires were a good 3 inches off the ground in front.  We finally found one we could live with.  They have limited sites with Electricity so also if you need that look around.

I will have to say that the facilites are really nice and very clean in fact I have never seen a bathroom floor that clean on a weekend.  

Speaking of weekends it does fill up most weekends so you will need to make reservations unless you want to use the hike in sites.

They have a recreation are also in the park that has a beautiful pool.  Picnic areas that are great and towers you can go up to see the Mounds. 

WE have spent 2 times there this summer and will be back next summer.

If you are there there are a few areas to visit.

Mt Horeb the Troll Capital.  It is a small town about 20 miles if that.  Has a Troll theme and you can see the trolls all over the town.  Some good restaurants and one of the weekends we were there was the Art   Tour it is in the entire area and had some great art studios you could visit.

Cave of the Mounds is another place you have to visit.  This is a great cave during the week they give guided tours on the weekend it is self guided but have docents around explaining everything.  Well worth the money and trip.  This is about 5 miles from the Park.

I will say no internet and cell phone was very spotty. It is also one of the darkest areas if you are into the stars, just put something on for Mosquitos. 

All in all a good solid 4, only down side was we were in a Motor Home and the not level sites was not the best.
