“Cobá is a Mayan ruin in the Mexican state of Quintana Roo. The site is thought to have been first settled between 100 BC and 100 AD and abandoned around 1550, upon the arrival of the Spanish conquistadors. At 137 feet tall, Nohoch Mul is the tallest Mayan pyramid on the Yucatan Peninsula and the second tallest Mayan pyramid in the world. It was discovered in the 1800s, but the archaeological site wasn’t opened to the public until 1973, as the thick jungle which surrounded it made it difficult to find. It’s off the beaten path, but nowadays you can get there by public transport or car.”
