We camped in the 100 campground and really enjoyed it! The sites felt pretty private with lots of foliage around, although you can still see your neighbors if you really want to. The ground was pretty hard, maybe because of the colder weather, so it was tough getting tent stakes and dog stakes in. My biggest gripe is that once the park office closes, they lock up the ice and firewood. It’s a big inconvenience for campers arriving later in the evening, especially after a long travel day when you’re ready to cook dinner by the fire. Thankfully, there are gas stations nearby that sell both, but when we went, one was sold out and the other only had a few bundles left so definitely plan ahead if you think you'll be arriving later! We’d definitely come back! I’d just love to see them add an after-hours digital system for buying firewood and ice like many other state parks have started doing.

Nice park, but expensive and needs better signage and dump facilities. Our price was $63 for out of state. Electric only; no FHU! We camped in site 121 which was very flat and allowed good Starlink reception. Bath house was very nice so showered there instead of our rig. Great trails and waterfall is spectacular. One more big negative beside price…only one dump station for three camp areas and it is not marked on any road sign. So keep the map they give you. The wait to dump was three deep on Friday at noon, so plan carefully.

This park is one of my favorites! We have camped here now 3 times and drive over 2 hours to get here just to walk the trails! The water falls are cool and fun to see in the summer and winter! They do a lot of activities for the kids around the park. You can go to the beach and swim and there are places to fish. I would highly recommend this park to families and or for yourself to camp at.

Loved this place for its group camp sites. Showers were nice and hike to the waterfall wasn’t bad. The kids were all able to do it and they loved swimming in the falls.

We stayed at the 100 campground in the middle of the week early May. Good news first- very large campsites with plenty of trees and shrubs for added privacy. I’m sure when all the leaves are in you won’t see your neighbors. The walking paths a wide and mostly shaded with beautiful scenery. I highly recommend the blue trail from the 300 campground to the falls. The falls are much more impressive than I anticipated and worth the walk. The park is pet friendly, and our dogs enjoyed the ~1.5 mi walk to the falls too! The Facts- It’s a little pricey to camp, your required to have a WI state park sticker ($38) plus camping fee of $33 a night for just electricity (20/30/50 amps)! If you want to just visit the park for the day it’s $10 in state, and $13 for out of state. Summary- We enjoyed our stay, but the price seems a bit high which is why only 4 stars. I recommend staying, just know what it will cost.
