A team from the Royal Ontario Museum first excavated the site in the early 1960s and found 250 structures spread over more than 1,000 square yards. At Plaza B, in the Temple of the Masonry Altars, archaeologists unearthed the grandest and most valuable piece of Mayan art ever discovered—the head of the sun god Kinich Ahau. Weighing nearly 10 pounds, it was carved from a solid block of green jade. The head is kept in a solid steel vault in the Central Bank of Belize, though it is occasionally displayed at the Museum of Belize. The jade head appears on all denominations of Belize currency. If the Masonry Altars temple looks familiar to you, it's because an illustration of the Masonry Altars structure appears on Belikin beer bottles. Because the Altun Ha site is small, it's not necessary to have a tour guide, but licensed guides may offer their services when you arrive.
Tours from Belize City, Orange Walk, and Crooked Tree also are options. Altun Ha is a regular stop on cruise ship
excursions, and on days when several ships are in port in Belize City, typically midweek, Altun Ha may be overrun with cruise passengers. Several tour operators in San Pedro and Caye Caulker also offer day trips to Altun Ha, often combined with lunch at the nearby Maruba Resort Jungle Spa. Most of these tours from the cayes are by boat, landing at Bomba Village. From here, a van makes the short ride to Altun Ha. If traveling independently or on a tour that includes it, you can stop at Maruba Resort Jungle Spa for a drink, lunch, or a spa treatment.
