Coba is the largest of Yucatan's archeological sites, it is also the least excavated of all the major sites on the Yucatan peninsula. Coba is none-the less important, to many archeologists. Coba is, simply put, AWESOME! Containing 20,000 structures, Coba was at one time home to as many as 40,000 Mayans. Coba, which means "Ruffled Water", was built along the shores of five shallow lakes. Coba is a striking site with magnificent pyramids and incredibly detailed stelae. The Nohoch Mul pyramid, the tallest on the peninsula, reaches 140 feet. Many experts feel that the pyramids here rival those of Tikal, in Guatemala. Multilingual guides are usually available, a good investment considering the size of this site. The size of the compound at Coba makes a visit from Cancun an all day trip. These ruins are considered a favorite stop for the more adventurous traveler.
