About Hamilton Preserve

Hamilton Preserve is a 232 acre park in Travis County, featuring beautiful undulating terrain and cool, clear water. Hamilton preserve’s pool and grotto were formed when the dome of an underground river collapsed due to massive erosion thousands of years ago.

The 45 foot water fall that creates a great swimming hole is the main feature to see. You should also also hike some of the nature trails along the creek. Swimming is allowed only when the water quality meets safe standards. Because of this, water quality is monitored regularly. You can stay up to date with information that is posted at the entrance booth and provided on the park’s telephone recorder message (512 264-2740). Ge there early, because the parking lot is sized for 75 cars. When all spaces are taken, cars are held up at the gate until a space opens. Drinking water or concessions are not available in the preserve; chemical toilets are provided.

Hamilton Pool Preserve Hours of Operation

  • 9 a.m. to 5:30 p.m. daily.
  • There is an entrance fee (credit card online, cash only in person).
  • Travis County honors the Federal Golden Age Passport and the Senior Citizen State Pass.

Pets are not allowed, even on leashes. Neither are visitors allowed to leave pets in cars while they hike and visit the water fall. Because of this, leave your pets at home for this excursion.

Extreme care is crucial for the delicate and beautiful ecosystem which forms the Preserve. You should understand the necessary rules for preserving the park’s unique beauty for generations to come.
