Zilker Botanical Garden, Austin

Zilker Botantical Garden are a small, pretty natural oasis near downtown.  They are located in the larger Zilker Park.  They aren't large or impressive enough to warrant a special trip, but worth a stop by if you are in the area.  They are free.  There are a lot of interesting little buildings and a play ground, so it is especially nice for children.
