The Caves Branch River carved its subterranean route through Cayo District limestone over two million years.
What emerged is a seven-mile network of navigable waterways threading through the Nohoch Che'en Archaeological Reserve, where stalactites descend like frozen waterfalls and crystalline formations glitter in headlamp beams. The Maya regarded these chambers as portals to Xibalba, the underworld, leaving behind ceremonial pottery shards and ritual altars that modern archaeologists continue to catalog.
Today the reserve protects one of Central America's most accessible underground river systems. Unlike the more famous Actun Tunichil Muknal cave, which restricts daily entries to preserve its archaeological integrity, the Cave Branch waterway accommodates kayakers and tubers year-round. The river maintains a consistent depth of three to five feet through most passages, with water temperature holding steady at 72°F regardless of surface conditions. Dry season flows from February through May offer the clearest visibility, while wet season currents from June through November add moderate speed to downstream sections.
The limestone vaults range from intimate tunnels barely wider than a kayak to cathedral chambers 80 feet high. Geologists identify three distinct formation periods visible in the strata: the oldest dates to the Cretaceous period 145 million years ago, when this region lay beneath a shallow sea. The middle layer formed during the Paleocene epoch as tectonic shifts raised the seabed into karst topography. The youngest deposits, still actively growing, produce the translucent flowstone curtains and soda-straw stalactites that define the reserve's signature aesthetic.
Belize Wild Land Adventures operates the primary kayaking concession from a basecamp six miles south of Belmopan. Their guides, many descended from Maya communities in the surrounding villages of San Jose Succotz and Benque Viejo, interpret both geological processes and ancestral cosmology. The reserve's buffer zone encompasses 600 acres of secondary rainforest where howler monkeys vocalize at dawn and keel-billed toucans nest in ceiba trees. Surface trails connect cave entrances to observation platforms above sinkholes that plunge 40 feet to underground streams.
