Float down the San Marcos River on a sturdy tube during this 6-hour tour from Austin. After a 45-minute drive from Austin to the river, escape the Texas heat as you float along the calm waters for up to three hours (depending on river flow). At the end of your float, your driver meets you for return to the Austin Visitor Center. Feel free to bring your own drinks and snacks to stash in the provided coolers with ice. Includes round-trip transport and use of equipment.
