Be sure to spend some time in the hills west of Austin if you can. Fredericksburg is a great town to visit. German food and great military museum. President Johnson's park. Great free driving tour. Nominal fee to tour the house(worth the $2). Great old town main street shopping. Marble Falls has a nice campground on a lake. A great granite rock to hike. A cavern to tour underground. Check out the campgrounds on Good Sam. I've stayed at La Hacienda rv park on the north west corner of Austin. A beautiful modern park. Also recommend Mller's rv park about 40 miles west of Austin . You can fish from the bank there. A couple things to do in Austin. See the baseball team play in Red Rock. Watch the bats come out of the 3rd street bridge(free). Visit the state capitol(free). Visit the river front. Visit the Lady Bird Johnson wildflower center. Anyway, you can tell I love visiting Austin and the Hill country.
