What I really appreciate Austin for is that the variety of awesomeness is concentrated in one city. You can feel the city-life if you go out to downtown, and by driving out from downtown for 5 min you can find a quiet spot by the water surrounded by trees. When I lived in Tokyo, this was never the case.
Because Red Bud Isle is a round shaped island, there can be many people elsewhere in this park, but you can still find a spot where you don't see anything or anyone but just nature.
I also love Barton Springs , where lots of happy people gather and enjoy the water. Every Austinite loves the springs. However I often enjoy this peace, science and space to myself. It feels such a luxury to feel the fresh water and see some green, while we are facing the extreme heat and drought in Texas.
Look at this happy face. June absolutely loves this place. :)
