A stunner! With a shady place to cool off, head just a few miles west of Austin and take a dip in the beautiful swimming hole featuring a grotto, canyon and 50 foot waterfall. It is open daily but check the website for updates – it closes when the water gets too warm. You can swim, hike, bike and even get a 1 hour guided tour that tells you about the history of the area. Pack a picnic, relax and look for the rare and endangered Golden-Cheek Warbler.
