We did the Range Rover Cave Expedition here. I highly recommend this excursion! The family loved seeing the jungle up close and personal and I loved driving a right hand drive stick shift military surplus Range Rover through the jungle. First we rode up the river in a boat for about 30-45 minutes, we saw a Morelets Crocidile up close and several beautiful birds and big iguanas.
Then we jumped in the Range Rovers and drove on some rough gravel roads, the local highway and about then 20 minutes of major off roading to another stopping point. From here we walked across a pretty substantial suspension bridge and hiked about 20 minutes up to a cave system used by the Mayans, during the hike our guide pointed out several local plants and their uses and explained how badly the jungle was damaged by hurricane Richard.
The cave requires bending and stooping so if that is not your thing you can wait by the cave entrance for the rest of your group to finish.
We hiked back out the way we came to have our light lunch which consisted of locally grown fruit, soft drinks, water and rum punch if you desired. There was a lady there selling lunch plates for $5 that consisted of Iguana, red beans and rice, fried plantains, and coleslaw. That was money sell spent, I had to go back for more once the kids got a taste of it. We were then herded onto a motorcoach along with our rum punch and driven about 30 minutes back to the cruise terminal in Belize City.
This is the part that really bothered me, we were bombarded by people peddling items aggressively, one lady even started braiding my daughters hair as we were walking into the cruise area. I had to physically remove her hands from my daughter.
