You’ll know you’ve arrived once you see the expanse of people lounging in the water in inner tubes. They can’t be resisted—you'll want to don a swimsuit, dive in, and claim one as your own. That’s why people float in Rio Frio—especially at Neal’s Swimming Hole, a section fed by spring water and maintained by a family-owned business since 1926. On the western edge of the Hill Country, 75 miles from San Antonio, the river tourism town of Concan has welcomed generations of Texans in need of lower body temperatures. Stay at Neal’s Lodges in cabins or campsites, or just come cool off for the day.
