A 37-mile drive along the Western Highway brings you to the Caves Branch River and its winding path, through the Maya Mountains and numerous ancient caves once inhabited by the Maya. Upon arrival at Caves Branch National Park, your headquarters for the day, your guide will issue floats and headlamps while providing a tour briefing. You'll take a 45-minute hike down a jungle trail where your guide will point out various plants, roots and herbs once used by the ancient Maya for medicinal purposes. Next, reach the entrance tunnel that heads into the underground cave system for the start of an eye-opening adventure. Then, float with gentle currents through the cave system. Enjoy intricate crystalline formations that line the caves, and the majestic rise and fall of stalagmites and stalactites that add to the serene opulence of nature. On several occasions, you'll emerge into the sunlight, only to enter into another cave system. Finally, your tubing tour will end where the hike began. You'll return your equipment and head back to Belize City and the ship. On your way back to the docks a stop will be made for lunch. Note: Participants must be at least 10 years of age and able to swim. The cave system and its waterways may cause claustrophobia in a very small percentage of guests. Wear suitable footwear for muddy, wet trails. Bring your swimsuit.
