The most extensively excavated site and the closest to Belize City (and Caye Caulker) is just 30 miles north of Belize City. Altun Ha can be easily reached by vehicle or by boat. Day trips are easily available from tour operators on Caye Caulker.
Almost on the Guatemalan border and accessible via a short ferry ride across the Mopan River. Xunantunich features a 130-foot high temple overlooking the river and Guatemala to the west. This is also an easy day trip if you're staying on Caye Caulker.
If you have the time and are interested in seeing impressive ruins ... Tikal, 50 miles into Guatemala, is a must. The expanse of the city and the majestic height of the temples are worth the trip. At least 3,000 structures dating back 6,000 years have been discovered on this site. We can arrange a day trip to Tikal by air.
Excavation only began in 1985 for this site, the largest in Belize and believed to be larger than Tikal. There are more than 4,000 structures covering 55 square miles. The largest pyramid, 140 feet tall, is the tallest man-made structure in Belize.
