If you're going to be in Austin you owe it to yourself to take advantage of one of the top rated spa destinations in the United States which happens to be located in the hill country just outside of the city. Lake Austin Spa Resort http://www.lakeaustin.com/ is absolutely stunning in its services, environment, and attention to detail. My wife and I spent a recent anniversary there and, though it was about $350 for the day for both of us, it paled in comparison to the $2k price one could spend at say, Burke Williams Spa in Santa Monica. Yet the services and ambiance were easily on par with that world class Spa.

My sister used to work at the Barton Creek Spa in Austin. She said that George W Jr used to go there for treatments when he was Prez. If it's good enuff for a president, well; ya know. Plus, they have a great jacuzzi and sauna she says.
