This was our first time staying at Dells Timberland and it was a really nice place. The sites are a pretty good size with lots of trees for shade and separation from your neighbors. If you have kids, there's lots for them to do. The pool is large with a shallow end with a wide stairway to enter and exit the pool. The deep end is about 6 feet. The pool area has a screen for watching movies each night. You can swim or just sit on a lounge chair and watch. There's a jumping pillow, a playground, tether ball, basketball, a large covered sandbox with lots of sand toys, horseshoes, sand volleyball and a couple other games that I don't know the name of. They also have a trampoline basketball game set up next to the jumping pillow that appears to be new and a water balloon wars game next to the pool. There's also a large game room and a covered tent/pavilion where you can play bingo and an inflatable water slide was set up. My kids loved all of this stuff.
The bathrooms were some of the nicest and cleanest I've ever seen in my 30 years of camping. The showers are large with large changing areas and hot water that you can actually control the temperature of. Most campgrounds I've been to have two temperatures, really hot or really cold. Almost no bugs in the bathrooms too, which is rare at a campground.
The staff is friendly, hard-working and constantly out and about maintaining the grounds and running the activities. This place is not run by seasonally employed teenagers. It's all adults who know what they are doing.
The only bad thing I noticed was noise. 90/94 is a mile or two away, but at night you can still here it pretty good. Although most of the Dells campgrounds are also a mile or two from the highway, so it would be hard to escape this noise no matter where you camped. There is also some train noise that is really loud at night and if I were sleeping in a tent, I would be pretty upset. I found myself saying "what?" to my wife a lot while sitting around the campfire at night because of highway and train noise. It's not really that bad, but it's definitely noticeable. It probably wouldn't stop me from coming back to Dells Timberland. We drove through the Dells Jellystone and I'm really glad we didn't stay there. It's right next to 90/94 and LOUD. Campsites are really cramped and expensive.
