Pilot Grove has a nice little public pool right by the trail, in the city park. The easiest way to find it is to go to the trailhead and look at the city map, then go by road. There's a direct unofficial cutoff from the trail, but it's not marked. There's also a good swimming area in Columbia, but it's about 5 miles from the spur junction with the main trail. On the other hand, if you are going in July, you might want to get up early, ride, then spend the heat of the day in the water. For information, the Columbia website is gocolumbiamo.com, and follow the links through parks and rec to Twin Lakes recreation area.
