Altun Ha, an ancient Mayan ceremonial center that covers five square miles. Archeologists did not know about this ancient site until 1963 when Hal Ball, a pilot and amateur Mayanist, noticed the existence of the ancient site from the air. Three plazas and thirteen structures mark the epicenter with the largest of the pyramids being The Temple of the Masonry Altars. This is where, in 1965, Professor David Pendergast of the Royal Ontario Museum discovered the almost ten-pound jade head of the Sun God Kinich Ahau in the tomb of the Royal Priest. Located only seven miles from the sea, Altun Ha was also a vital trade center during the Classic Period (250-900 AD) and is believed to have had a population of about 10,000 people. 

For a panoramic view of the surrounding countryside and as long as weather permits, climb the stone steps at on of the three of the main temples. The view is just awesome.
