Paddle into Belize’s karst underworld and swim the crystal-lit chambers on a six-hour guided trip. Navigate narrow passages, explore waterfalls and cliff-jump, then refuel with a riverside lunch of handmade tortillas.

You push off at the cave mouth with a paddle whisper and the river seems to dare you forward — dark water threading through collapsed limestone, headlamps carving cones into vaulted ceilings. The first chamber opens like a cooled kiln: dripping stalactites, polished flowstone, and pockets of sunlight that make the water glitter. Guides call out landmarks; you pass carved ledges and narrow squeezes where the cave narrows and the current nudges the kayaks onward.

Wear grippy water shoes
Stony cave floors and wet ledges are slippery—closed-toe, non-marking water shoes improve traction for paddling, swimming and cliff exits.
Secure electronics in a dry bag
You’ll pass swimming spots and waterfall alcoves—keep phones and cameras sealed to prevent water damage.
Know the weight limit
The tour caps at roughly 295 lb (134 kg) per participant for kayak and safety considerations—check before booking.
Hydrate before you start
Tropical heat and physical exertion make pre-trip hydration important; guides provide a riverside lunch but bring a reusable water bottle.
Closed-toe water shoes
Protects feet on slippery cave rock and when climbing in/out of water.
Waterproof dry bag (10–20L)
Keeps electronics, IDs and extra clothes dry during swims and splashes.
Reef-safe sunscreen and insect repellent
Protects skin in open sections and on the walk to/from the cave while minimizing environmental impact.
Quick-dry clothing and a lightweight towel
Speeds drying after swims and keeps you comfortable on the return drive.
