Wonderful little State Park offering everything from kayaking & hiking trails to camping etc. The camping experience includes choices ranging from primitive sites to cabin rentals and everything in between. Note: some cabins offer a beautiful overlook of this gem of a lake. Fall is my preferred time of the year and this park does not disappoint when it comes to viewing the spectacular array of color.

Great campground. Very shady sites available with nice old trees. Plenty of room to camp. The lake is quiet and the beach was pretty good too. Not much bad you can say other than there wasnt any soap in the restrooms. The sign said it was on backorder.

Nice lake, very laid back. You can have big boats, but can only go idle speed, which is a little too slow of pace! Very nice for kayaking and paddleboarding tho. Apparently you are not supposed to swim there either.... really dont understand that one, as it has a beach!! However... everyone was swimming today because it was hotter than hot! The water was 88°!!!

Found a picnic table under a tree enjoyed our lunch while looking at the beautiful tree line. Fall colors are the best.

A great example of an Ohio State Park. The facilities and campgrounds were clean and well organized. The lake was beautiful for swimming and boating. The price for a campsite is very reasonable. Overall no complaints at all. A very nice way to get out of the house for a few nights or if youre lucky enough, an extended stay. Good job Ohio Parks!

Relaxing. Inviting. Peaceful. Endearing.Family destination in past years, and to become yet again! Another happy place!

We camped here the weekend of 10/9/20 and while the campground was fine and the scenery beautiful, we had an extremely creepy experience where a stranger attempted to separate my husband from myself and our small children near the Lotus Cove trail. The incident was reported to the authorities and I am posting here as a warning to other families to be careful in isolated areas of the park.

I love Cowan Lake State Park for camping!!! Ive been coming here since I was a kid and, to me, its still THE BEST!!! Large sites so you dont feel like youre on top of the next camper, quiet nights, wonder shower and restroom facilities and friendly people.

Nice lake with sailboats, pontoons and a kayak launch on the beach. Shallow water so kids are safer going out farther. Downside was the gritty, rocky beach and some bigger rocks out in the water. Really need to watch where you are stepping for that reason and because of so many geese. Although animals are not permitted on the beach there were a lot of dogs on the beach and in the water.

Beautiful campsites with plenty of space. Fishing was awesome and the nature trails are beautiful. Dog friendly and well cared for. Wore my puppers out completely

Spent 2.5 days there at one of their cabins. The cabins, though dated, were comfortable. The a/c was very good and kept the cabin cool. I went fishing and it was fun. The only complaint I had would be the mattress. It was not as firm as I am used to. They could also sometime in the future provide internet access. Other than that it would go back again.

Beautifully renovated cabins. Flat, large campsites. Decent camp bathrooms and showers. Gorgeous views and nice hiking trails. Ive been coming here my whole life and I love it!

Great camping area. Commissary isnt open yet and no events but still nice place to camp

Nice getaway near my daughters. No complaints. Its actually in Clarksville

Good clean and quiet park... dont go here though, because I like it all to myself!

Trails need some love but restrooms, shower house, sites and beach were all lovely. Enjoyed my stay!

Good place to go with family. You camp there they little grills so you can cook.

Kids have fun and so do the adults! Beautiful setting!

Decent Campground not much shade in there camping area friendly staff

Site#208 was clean, spacious, and close to level. Was quiet during our visit.

Beautiful, safe, clean lake for fishing or swimming, get trails looks of wildlife.

Quite nice place to camp would be nicer to have full hook up but dump stations are easy to navigate and clean

Love camping here. Although it is unfortunate that the ash trees had to be removed, the park is still very beautiful and well maintained. Several nice play areas for children too! The trails are also nice and well marked. There are many free events throughout the year as well. Very enjoyable!!!!

Great morning to be kayaking on the lake. All covid 19 protocol followed here. Camp store closed but can buy ice and firewood at front entrance.

Lovely small lake with some parks, playgrounds and shelters scattered around. More of a fishing lake than a boating lake since there is a 15 horse power limit. Hopefully they can get a grant or something to help eradicate the lotus flowers. While they can be pretty, there is a section that is just over run with them so you cant take a boat in there. They have managed to keep them at bay but eradication seems unlikely.

A beautiful Lake for sailing and kayaking.... The park campgrounds are very peaceful and clean with shower facilities any cute little commissary that serves ice cream and sandwiches..... Highly recommend for a fun little getaway

Hard to judge actually, everything was closed down due to the covid 19 pandemic. Looked like a nice place from what I could tell by the entrance area and buildings. Was interested in the cabins, have since looked them up online, they look awesome, looking forward to renting one if possible this year. Stay safe & healthy everyone!

We camp here often as its not too far from our house. This year the campground seems a little more worn down, maybe its because we have camped at so many other places in the past year that we have more campground experiences to compare it to. Its still better than Caesars Creek Lake SP, but only because its more wooded, more shady. The bath houses are atrocious, seriously in need of an upgrade, probably the worst Ive ever seen. Campsites were muddy, some had straw spread on the ground to counter the dirt/mud conditions, and ours even had a second fire pit that someone built instead of in the designated fire ring. Who does that??We like kayaking on Cowan Lake as its a limited horsepower Lake, so no powerboats or jet skis, this is probably the best thing about this place.

One of the best around Cincinnati.

Rented Jon boat at marina, caught one fish in four hrs, small bass back in a cove,. Jon boat is ok but a pontoon would have been better , if you want a pontoon for 7 hrs make sure you get there early so you have enough time to enjoy the lake..

Love this place after being away for thirty years up in Alaska and getting to come back here again

Nice clean sites.clean bathrooms.like a little community! Great staff

We always enjoy kayaking here in August to see the lily pads

I hadnt been to Cowan Lake since I was a kid. Its still a nice family spot but the sand/beach has eroded since I was there last. The water is very dirty and sandy as well. The beach could use a rehab!

This place will always have great memories

Eh it was alright. The Ohio State Park website is not super user friendly and you must use this site or call to reserve your spot. Also, the beach area is over ran with geese. Their poop litters the entire beach. I also had a racoon steal an unopened bag of marshmallow off the picnic table when I ran to the bathroom. Sneaky little dude stole my smore glue!

Fun place but the gos leads you to the camp ground follow the beach sign in brown if your going to public beach

Really nice park, our site had plenty of trees to block the hot sun!! Comfort station and showehouse were rustic looking and very clean!!

Look closely and youll clearly see the Big Dipper. 25 Aug 2019

Lotus plants and Lilly pads in full swing!!! One of my favorite places to visit during August!

What a secret gem. Large flat, or nearly flat, sites. Liked it so well, spent a second night.

The class held by Mandy was wonderful!! Learning many new things about our local birds in our area is priceless!! I cant wait for another educational class at Cowan lake!! Im so grateful to have found out about all the classes being held there all year long!! Becky and I both loved it!!

Spacious sites, wooded and un-wooded, relatively level, clean bathhouse, friendly campers, no water or dumping at the site. Beech quality is average, nice lake for small engine boats. Overall a very quite campground. Due to COVID camp store & nature center was closed.

It was beautiful here. So much to see. A nice drive to take and plenty of good fishing spots. Awesome place!

Better than Ceasers and that all you need to know !

Nice facilities, beautiful place.

Its a pretty lake, but the fish were not biting!

My babe took me fishin! Makes me smile!

Loved it! Great lake for kayaks (10hp or lower), tons of great sites. Large commissary with seating outside overlooking the lake. Hand scoop Perrys Ice Cream, snack bar for lunch and breakfast. All items made to order. Naturalist cabin and activities for kids too. Cant wait to come back!

Rude people and nobody cleans up after there dogs .its a mess on a lot of lots there are mud holes.

Beautiful! Awesome ,friendly staff. One of Ohios best kept secrets!

Great place to kayak. No

A wonderful place to visit. Go for walks in the trails, and to picnic and to go fishing.

Great place to fish. Tons of countless geese. Quiet place

Keep their bathrooms nice and clean. People seem friendly

Great place for kayaking! The Lotus blooms are gorgeous. Lots of feeder creeks to paddle too. Very quiet during the week!

Great place to take fall pictures

This place is a really nice campground.

Close to me, nice trails, great place to walk

Very serene. Medium sized manmade Lake as far as Ohio Lakes go. Lots of sailboats. Great place to take a rowboat, go fishing, or just float on the lake. 10hp limit for boats with motors and no alcohol permitted.One important note, there are no trash bins, so plan to carry your trash with you. While littering is always wrong, the beauty of this park would make even the most apathetic person feel intensely guilty for such an act.

Nice clean park and beach

Huge lake that accommodates all sorts of water activities, plus camping and picnic areas.

So cozy and clean. Beautifully maintained and very friendly management.

Enjoyed watching the boats. So peaceful!

Great state park. Highly recommend!

Nice lake, lots of activities. Is pretty crowded though.

We rented a pontoon boat for a few hours with friends and we had the best time. It was peaceful and relaxing. We didnt catch anything but we cruised around the lake. The boat rental was reasonably priced, everyone was friendly. Cant wait to go back. Looked for a cabin rental but they were booked every weekend.

My husband and I love Cowan Lake for kayaking. Our pups love it too! Water is relatively calm so its a perfect kayaking spot to explore.

Amazing wildlife, cabins surpassed expectations, and the park was clean and fun.

One of the smaller state parks, has plenty to do but less than some others I visit regularly. The park is definitely among the cleanest Ive seen though! The lake has a horsepower limit on boats which both kinda sucks..but is nice too. On the bad side it means I cant bring my pontoon here, not like I can really get on it and fly, but anything over 10 is a no go unless you have a dinky motor or a trolling motor ...just go to Caeser Creek on the other side of 73. On tbe other hand, kayaking at the lake is beyond amazing because of how calm the water is. Most definitely recommend it.The campground here is fantastic too, clean and full of trees for shade. It actually looks like a woodland area, not just grass with paved spots for campers and a fire pit.

The naturalist and volunteers have done a great job maintaining and improving the trails. April 7 and the millions of trillium are in full bloom!

Its a beautiful place. Its really starting to improve since the emerald ash borer debacle a few years back. Theyve remodeled the bathhouses, planted new trees and gave the play equipment a nice face lift, as well. I highly recommend visiting the lake and the hiking trails, too. It will not disappoint!

We went on a cold, rainy day in May, but we had a pretty great time hiking. The trails were expectedly muddy, but well marked, easy to find and lead us on some fine adventures for a Saturday. We cant wait to go back during nicer weather, maybe do some fishing while there.

Quit found the fish and had a great day with family!

We love Cowan Lake but the power went very low on Saturday...would not run the air conditioner.

It great for kids!! Are Family had a lot of fun!!

Beautiful lake! Beach needs cleaned up and very muddy near shore

We love hiking around Cowen Lake. The trails are easy enough for the kids to navigate, but have fun obstacles (fallen trees, bridges, ect.) to keep it interesting as well.

Beautiful park with lots to do!

Great kyaking spot. Quiet except for the birds.

We go here often and love it.

First fishing outing of the year...Grandkids caught some small ones...

Very nice well kept

Boats cabins giant Park good friendly people and still close to the grocery store for emergency supplies fun for everyone

Ed and Mandy were amazing to my family! We came across the Naturalist Cabin while on a road trip, these 2 were so great to show us around. Made our trip exciting!

Nicest cabin I have ever stayed in...TV & fireplace...nicely furnished. Comfortable.Super cleanWe had a blast!!!

Ive camped here since I was 5 , its my favorite place on earth!

Nice Campground had a lot of fun

Always amazing. Best state park camping around the area. 4 generations of my family have camped here and we all agree its awesome.

A great place to fish and relax.

Nice place, cabins are slowly being renovated which helps as the older units are very dated. The Halloween event is always a blast.

Very nice State Park to visit camping, fishing had a great 4-day stay, beautiful part of the country.

Very nice state park. Electric only but water and dumping nearby. Lots of good shady or open sites. A public beach and boat launch close by. Good ice cream too. Clean campground.

Very nice and clean campground. Different weekend activities, friendly people. One of the better campgrounds Ive stayed at. Still havent got to check out everything here yet.

We always rent cabin 18 because of the views of the lake from the back porch, but the trees have grown to high and you can no longer see the views. Camping lake beach needs to be cleaned up.

Wonderful place to bring the family! Its very clean, has lots of activities, playgrounds, ect. My 3 year old had a blast! Definitely would recommend a trip there!

Great place to go an relax an take walks an fish .just a great place for summer activities

Its beautiful and fun. Great camping experience!

Definitely a small lake but doesnt mean its a bad one. Not bad for most boats.

Well maintained. Clean. Lots of activities and facilities for singles couples families. Limited hiking trails (only two). Lotus trail requires wading thru water to hike it (depending on lake level).
