Percy Quin State Park is a beautiful nature reserve around Lake Tangipahoa near the town of McComb in southern Mississippi. The order of the day at Percy Quin State Park is camping, golf, and watersports like jetskiing, fishing, and boating, though they've unfortunately drained the lake for renovations so you should check ahead to see if the lake is opened.
Really, the best thing to do at Percy Quin State Park is go camping. They have set-ups for RV campsites but the best part are the cabins they have in the woods near the lake. For less than a cheap hotel, you and your family can get a nice rustic cabin with beds, a place for a campfire, and all the electrical and plumbing amenities you'd want. We don't want to get toooooo rustic, after all!
The cabins they offer range from basic to delux with the price spanning $35 to $100/night, but keep in mind that you get an entire cabin to yourself! When you get a cabin, you also get access to swimming pools and the lake, so it's a little bonus. If you're looking to escape from the city into a world of pines, magnolias, and lakes in southern Mississippi, Percy Quin State Park is the place!
