Austin travel tips

1) Join the ghostbusters or architecture lovers visiting Driskill Hotel in Austin

2) Mind that Barton Springs Pool welcomes visitors all year round

Barton Springs Pool is a lovely place of childhood memories of most Austin residents. In fact, it’s a huge outdoor swimming pool with water from nearby natural springs that keep it relatively warm all year round. In case of scorching hot weather, check it out!

3) Don’t get surprised at meeting topless women in public

In Austin, it’s allowed to go topless in public. One more “Keep Austin Weird” in action. There is the only nude beach in the state of Texas. You may come there even without being naked. However, don’t stare and take photos of nude fellow sunbathers.
