Hamilton Pool Preserve, about a 45 minute drive from Austin, TX, is one of the most beautiful places to spend a hot, Texas afternoon. A short hike from the parking lot through a wooded forest opens up onto a scenic, natural pool. The small beach to one side is usually dotted with sunbathers and picnicing families, enjoying relaxing day out of the city.

The park has a limited capacity, and often fills up on warm weekends and even weekdays. Be sure to arrive early to avoid lines.
