Kayaking on Canyon Lake is really mellow. Kayaking on the Guadalupe or the Blanco can be a bit challenging (current takes you under dead trees (snakes) and into small rapids ocassionally. Make sure you know where the dams are! Went over one for shits and grins! Cowabunga! Have a good, kayaking vest and a helmet! Lots of submerged trees at the bottom of a damn!
