Start with an easy, 30-minute shaded hike through the tapir corridor of the subtropical rainforest, crossing shallow riverbeds as your guide introduces ancient Mayan cave lore and indigenous medicinal plants. At the river entry, slip into the calm, crystalline waters. Drifting in linked tubes illuminated by LED headlamps, float through expansive limestone cavern systems known to the ancient Maya as Xibalba—the sacred underworld. Marvel at ceiling formations, crystal curtains, and underground echoes while your guide navigates the river’s gentle currents safely downstream. On-site facilities include secure storage, spacious changing rooms, bathrooms, and water-shoe rentals. - Wrap up your adventure with a freshly prepared Belizean meal. As you make your way back to your port terminal or hotel, enjoy a narrated sightseeing pass through Belize City, learning about its colonial architecture, historic swing bridge, and vibrant coastal culture.
