Located deep within the jungles of the Yucatan peninsula, Coba was built in the classical period, which dates from around 500 to 900 AD. The ancient city once covered an area of some 27 square miles crossed by a network of 45 roads or sacbes, which also connected the main town center with other smaller communities. The main sacbe is 62 miles long and connected Coba with Yaxuná, a notable archeological site located in the neighboring state of Yucatan. The main temple of Coba is the highest in Riviera Maya, reaching a height of 138 feet. Visitors to the site can still climb to its top for stunning views of Coba and beyond.
