Binder Lake has some great scenery and is large enough to kayak for about 1 or 2 hours. It also has great fishing if you want to do that.
Once you come into the park you will come to an intersection. Go left here. The lake will then come into view. Take the first road you see on the right. Follow this road all the way to a building that has a playground across from it. Park in the parking lot next to the building. There is a little dock here that you can drop in from.
