Mount Bonnet + Barton Springs

During the week in the evening, we were having dinner and watching the sundown on a mountain/hill nearby.

Afterwards, we went to Zilker Park, the citiy park, to swim in Barton Springs. Every day from 9-10pm, there is a free swim, but since the water comes from a spring it is f****** cold. However, as it is about 30 degrees and humid even at night, swimming in this pool is a nice refreshment.
I already went there a couple of times by bike during the week, I will do it more often in the summer.
