How to Visit Hamilton Pool Preserve

Hamilton pool preserve Texas is one of the most beautiful natural pools from Texas, the perfect place to cool off on a hot day of summer.

This place designated a nature preserve by the Travis County Park in 1990, is without any doubt, one of the most interesting and unique swimming experiences in the whole state.

Nestled 0.75 miles upstream from its union with the Pedernales River, Hamilton Creek spills out over limestone formations to a spectacular 50-foot waterfall that careens into the crown of a precipitous box canyon.

When I first saw it, I thought I was in a tropical place because it looked so interesting. But actually, I was in the heart of Texas.

The house is in Texas hill country, near Austin. You can only swim here if you have a reservation.

This pool is natural and very old. It was created when the roof of an underground river broke because of erosion.

Erosion is when water or wind wears something down over time.

About Hamilton Pool

Once you get close to this swimming hole with a 50-foot waterfall you will think you are in an exotic place.

The natural pool is located in the middle of Austin, Texas.

It is a circular swimming hole that is partially shaded by a rock.

This overhang rock is what it remains from the ceiling of a cave after everything collapsed many years ago.

The pool is a good size. It is 150 meters in diameter and 26 feet deep. The water in the pool is clean and monitored by experts.

The pool is located in an area that is 230 acres. During spring and winter, the water is too cold for swimming.

The temperature can drop below 50 degrees Fahrenheit sometimes.

If you want to swim in the pool during the summer, you need to plan ahead.

You need to book your spot early if you want to be sure you can swim on a hot day.

The water from the pool comes from a waterfall, but it has a relatively constant level all year round because the waterfall never completely dries, but in dry times it does slow to a trickle.

Because of water temperatures, we recommend you to visit this pool during summertime with a prior reservation.

A day at Hamilton pool

When you arrive in the morning, there will be plenty of space. But make sure you arrive before the opening hour. That way you can park in the parking lot.

Otherwise, it will be hard to find a free parking space.

From the parking lot to the swimming pool, there is a short hike.

Before you start walking to the pool, make sure that you have everything that you need.

This will save you from having to turn back around and go to your car to get it.

You can wear flip-flops, but they might not be very comfortable.

We suggest taking some other shoes that are more comfortable for you to go down to the pool.

Facilities available at Hamilton Pool Preserve

The area is not developed and there are not many buildings or facilities.

This is because the government wants to keep the natural area as it is.

At the entrance, you will find bathrooms. The pool is a short walk away from the bathrooms.

There are also picnic tables where you can have a snack.

There aren’t any shops, restaurants, or food trucks nearby, so make sure you bring everything you need for a day at the pool.

Down, at the poolside, there are no swing ropes to jump into the water because as I said earlier, the human intervention over the place is reduced to a minimum.

You can bring tubes with you to lay on in the water, or you can swim and stay on your blanket on the shore.

You can stay as long as you want during the interval you book.

At the picnic area near the entrance to the pool, you can have a snack from home.
