Belize: Xunantunich Mayan Ruins
Xunantunich is a Mayan archeological site just half a mile from the Guatemala border. It contains over 25 pyramids and palaces, the biggest being El Castillo (a whopping 130 feet tall and second tallest building in Belize. Still!). Spectacular views from the top of it (gruesome climb) afford sightings of Guatemala, river, and mountain ranges and villages.
