Just one among the more than 50 archaeological sites in the area surrounding Zihuatanejo, Xihuacan opened to the public for the first time in 2013. While it lacks the scale and grandeur of larger archaeological sites in Mexico, such as Chichén Itzá, it still has the capacity to awe and humble, especially when you’re standing atop the pyramid. It also features a ball court. Estimated to cover 12 kilometers (eight miles), this site is still not excavated fully—which means there’s still more to discover in the ground beneath your feet.
