Seaislegal,
I think it was Belitours. I was able to book it through the dive operation that I was diving with. I am not sure of the cost, Maybe around $115, but not sure. When I am on vacation, I just do what I want to and worry about the bills later. We flew to Municipal and were picked up there. It included lunch, which was a Belzean chicken tamale....very good!! We also got a pineapple while going through the rainforest and had that for dessert. Also got to taste a couple of other native fruits. Our guide was Luis, who is a native medicine man. Very knowledgeable!
Have fun!!!
