Altun Ha Tour: spanning a 25 square mile area roughly an hour from Belize City, Altun Ha is made up of two central plazas surrounded by towering temples that enclose the palm strewn land. The larger of the two plazas, Plaza A, is the site of a mysterious tomb discovered beneath one of the temples called Temple of the Green Tomb. Jade, jewelry, flints and skins are among the three hundred remnants that were unearthed here. Cave tubing provides thrills to suit nearly any age and fitness level. After a brief 30-minute hike to the entrance of the cave, inner tubes are used to float along the Caves Branch River. Hear the echo of your own voice bounce off the distant walls. Listen to the water dripping from the ceiling, creating spectacular formations in the stunning chambers. And while you might be expecting dark and claustrophobic passageways, you are likely to find enormous chambers and cathedral-sized rooms. You will be driven back to your hotel or cruise port at the end of the tour.
