Nice state park. Nice sand, PLENTY of parking, bathrooms that are pretty clean, hiking paths nearby. Wish there was a bit more beachfront, but a great stop if you are in the area.

Great Lake! I go a few times a week. No life guards. No garbage bins so plan to take your own trash when you leave. Geese and Cranes all live on the lake and are not afraid of people. They will walk up to you. Many people feed them human food - please don’t do this. Nice bathrooms, electric plug in for blowing up your floats, a spigot to rinse your feet.. other cool features: volleyball courts, bike path, platground

Get here early to snag a spot because the beach is small. There is a nice beach and picnic area.

Had a great day at the beach here

I like fishing this little lake.. Clean water & well maintained by the state. Kayaking, motor-less boating, swimming or just hanging out on the beach are all a good time.. And there is even a dog swim area too !!

Great small non-motorized lake. Plenty of panfish, though you have to work through the dinks. I've only gone a couple of times though. Supposedly there are big panfish here. Deepest part of lake is only 15 feet.

The best family picnic spot

Nice place to swim

Nice camp sites, pretty clean restrooms. The lake is something that needs to be preserved. Best place for a catch clean and cook.

really nice campground!! lake was good also. really decent fishing for the size.

We love this park for our yearly family outing. Very peaceful and relaxing.

Came here for camping at the campground. Always a nice camping experience. Beautiful in the fall.

Clean site. Quiet during the day in October. The site needs a new fire ring. The current one is rusted and deteriorating.

This place was dirty. The bathrooms were disgusting. I give it 2 stars because the swim area is nice.

So nice everyone loves it and then it's crowded. Great man-made lake

Beautiful lake. Easy access for kayaking, canoeing, and stand up paddle boarding. Lots of beautiful birds and surprisingly good fishing with plenty of panfish and bass. Can’t wait to go back.

We've camped here for years, we love this campground. It's well groomed and quiet.

This is certainly a great summer campground, not that I would know because I only go here during the off season. Just a few hearty souls, no water provided, and only vault toilets...but that does not ruin the charm. I stay here multiple times all winter. Just brilliant

11/07/21. Ottawa Lake Fen State Natural Area - located in Wisconsin Kettle Moraine State Forest Southern Unit. Beautiful small lake, year-round campground, children play ground, as well as many other facilities: performance stage, fishing deck, beach... Please view the video to see if it is a good place for your family or party gathering. See the video on Youtube, search: Ottawa Lake Sweet Calming

Crystal clear water!

I love taking the kids here. Ive never had a bad experience. Safe place and nice people.

We spend many weekends here with the family. We camp here or drive out for day trips often. Great place to make family memories. Very clean!

Wonderful park and great day for a race!

It's a peaceful place to go, Beautiful Mother Nature😍🤗🙌🥰😇👍🤽🏊⛱️🌅☀️🌞😎💯❣️

Great place to swim during the summer. The water is always generally clear and warm.

Have a good time ever summer

Love this place!
