One of the last things you would expect to find in Texas is a stunning emerald green natural pool that is fed by a 50 foot-high waterfall. The Hamilton Pool Preserve is gently tucked within a small grotto or cavern. It is located off of Highway 71 approximately 23 miles (37 km) west of Austin, Texas.

On the ceiling and nearby cliffs you will find maidenhair fern, a variety of moss and numerous social song birds, the cliff swallows. You will also find large slabs of limestone that embrace the water’s edge. In addition, the preserve is home to the endangered golden-cheeked warbler that can be found in the Ashe juniper (cedar) uplands. According to Travis County Parks, the preserve is part of the Balcones Canyonlands Preserve (BCP) which contains more than 31,000 acres of endangered species habitat. The BCP is owned by numerous organizations like the Nature Conservancy, Travis County, Travis Audubon Society, the City of Austin, the Lower Colorado River Authority and private landowners.

One of the ultimate trips that are budget-friendly is basking in Hamilton Pool. Explorers alike will agree that the pool is pristine and breathtaking. Although it can get quite populated with tourist and swimmers, there is still something very magical about the place. Research reveals that Hamilton Pool dates back to the 19th century. There are more modern stories of the sacred area that date back to the 1800s when Native American like the Lipan Apaches and Tonkawa occupied the land. However, by the mid-1860s, Morgan C. Hamilton owned the property (his brother Andrew Jackson Hamilton, was Texas governor (1865–66). Today, after much abuse from massive public visitors plus grazing cattle and sheep, there are ongoing land management practices to restore the pool back to its original state. Some of the management includes water quality monitoring, biological inventories, endangered species surveys, prairie restoration and prescribed burns.

To reach the ancient swimming pool you have to hike in a quarter of a mile. The trail is steep and rocky with uneven steps. A good pair of hiking boots or sturdy tennis shoes is highly recommended. The hike to the pool takes about 15 minutes, depending on your fitness level. On the way you will enjoy a big diversity of vegetation and rare plant species-

  • Juniper
  • Red bay
  • Oak savanna
  • Chatterbox orchid
  • Canyon mock-orange
