Just returned from Big Hart, Can't say enough about this campground.. Sites are large, secluded and clean. We camped here for 4 nights and it was so relaxing. We camped in a 30 foot fifth wheel, We also camp with our 3 dogs, they enjoyed it as much as we did. The lake is wonderful, we swam, played and paddled around in our little boat.The staff is amazing Nanette and Tonya were awesome, always a smiling face and very helpful. camped from June 17th to June 21st, 2017. We will return many times.
