Without question- the Overnight Caving Expedition is by far the most fun-filled and ambitiously adventurous guided tour that you can add to your bucket list of fun things to do in Belize! Created to include the famous Black Hole Drop, this adventure takes you completely off the beaten path and allows you to camp out at the Awe-Inspiring rim stone dam entrance of the Actun Loch Tunich river cave system. Camp is set up inside the entrance and dinner prepared. Then on to exploring the upper crystal chambers which were the ceremonial sites of the ancient Maya. The next morning, after a hearty breakfast, you trek down another 400 feet along cave cliff walls on routes of the ancient Maya to the Actun Loch Tunich underground river, with over 24 kilometers of mapped passageways. Explore in the steps of the ancient Maya, past bubbling springs and an underground waterfall.
