Went to the Dellls last summer. Stayed at Devils Lake State Park. A lot of the campground is built into a steep slope and it was difficult to get the trailer level. Had to dig a hole for the wheels on the uphill side and used every piece of blocking we had to raise the tires on the downhill side. Didn't spend much time at the park, but there seemed to be good trails to walk and swimming at the beach. Pretty hard to ride a bike anywhere. We checked out Mirror Lake State Park, pretty nice and much more level, and much closer to the attractions at the Dells. We spent 2 days at Noah's Water Park, had a great time. Make sure to do the Scorpion water slide. The Ducks tour is pretty cool too. Lots of other touisty things to do too.
