The Alamo and the iconic San Antonio River Walk earned the dubious honor of being among the most overrated tourist traps in the world, according to a USA TODAY report published last week. According to USA TODAY’s  report, the San Antonio River Walk is the biggest tourist trap in Texas and the No. 46 top tourist trap in the world. The Alamo wasn’t very far behind, coming in as the No. 48 biggest tourist trap on the planet.
