Barton Creek is a major contributor to the recharge zone of the Edwards Aquifer, making the surrounding area environmentally sensitive.
The limestone bedrock at Twin Falls shows distinct signs of erosion from centuries of water movement through the Greenbelt.
The falls are a popular destination for rock climbing enthusiasts who utilize the limestone cliff faces in the immediate vicinity.
Local geological formations in this area are part of the Cretaceous-aged Edwards Limestone, known for its porosity and karst features.
Twin Falls is a geological feature located within the Barton Creek Greenbelt in Austin, Texas. The site consists of a series of limestone ledges that create cascading water drops when Barton Creek is actively flowing. It is part of a larger 7.9-mile trail system popular for hiking, trail running, and mountain biking. The terrain features exposed limestone bedrock, riparian vegetation, and significant elevation changes common to the Edwards Plateau transition zone. Water levels are highly variable and depend entirely on recent rainfall in the Barton Creek watershed. During drought conditions, the falls frequently stop flowing, leaving behind stagnant pools or dry rocky basins. The area is managed as part of the City of Austin park system and serves as a trailhead access point.

Check recent rainfall reports online before visiting, as the falls are often dry during hot summer months.
Wear sturdy footwear with good grip, as the limestone rocks near the creek bed become slippery when wet.
Bring your own water and supplies, as there are no amenities or potable water sources available at the trailheads.
Do not visit expecting a constant waterfall; avoid swimming if water levels are low due to stagnant water health advisories.
Stay on marked trails to prevent erosion and protect native vegetation; dogs must be kept on a leash per city ordinance.
