Cayo gets some more publicity with 3 extreme inland adventures. Ultralight flights, cave tubing - misspelled as cave tumbling - and jungle horseback riding are the main focus. Xunantunich and Chaa Creek get mentioned in the article too.
"One of the most spectacular & accessible Mayan ruins in Belize is Xunantunich. This architectural wonder is set on a leveled hilltop and is reached by crossing the Mopan River on a hand-cranked ferry. The ruins are impressive when viewed from the ground but the sheer size and magnificence is not fully comprehended until seen from the sky. A bird’s eye view from a gliding ultralight is the best way to fully experience the wonder of the ancient Mayan Civilizations. There’s nothing like reaching a height of 3,000 feet when the pilot turns off the engine, and one gently glides over the ruins in absolute silence."
