"Texas has no shortage of stunning swimming holes, and Wimberley's Blue Hole swimming area is a prime example. Old-growth cypresses provide shady spots when you need to cool down, while rope swings offer an adventurous entry into the water. This is a popular swimming location, so during the season (May through September) you'll need to make a reservation on the website. Blue Hole Regional Park also includes 5.5 miles of trails, picnic areas, an amphitheater, and basketball and volleyball courts." - Travel + Leisure Editors
