Head inland towards the Maya Mountains to the Nohoch Che'en Caves Branch Archaeological Reserve, Belize's premier cave-tubing destination. At the base facility, gear up with your provided helmet, headlamp, and life jacket. Follow your guide on a scenic shaded rainforest hike across the riverbed, learning about native wildlife and medicinal plants. At the launch site, settle into your tube and drift into the Caves Branch limestone caverns. As your guide steers through gentle currents, illuminate cathedral chambers filled with towering stalactites, stalagmites, and crystal formations while discovering why ancient Maya priests revered this subterranean realm as Xibalba- the portal to the underworld. Exit into the sunny open river and float back to base to rinse and change before your air-conditioned return transfer to Belize City, timed with ample buffer for your cruise or travel.
