Guadalupe River, Canyon Lake and Cormal River – near New Braunfels. Take the IH-35 to New Braunfels and go tubing on the Guadalupe River.

San Antonio has lots of hotels and places to stay and of course lots of great Tex-Mex and other foods to enjoy. The highlight is most certainly seeing the Alamo, Riverwalk and Missions but there is a lot more to see here too. Hopefully some of the information above will help you do that.
