Rainforests - It doesn't get any more biologically diverse! No wonder they`ve been labelled 'jewels of the earth`. Ecotourism in a lush, vibrant, colourful and downright exotic ecosystem makes your ecotourism traveling experience so much more fruitful. If you're going on an ecotourism trip in a rainforest be prepared to be awestruck by their grandeur and mysteriousness. And, if you really want to expand on the opportunity, pick a destination with tropical beaches and islands, that way adding a lot more to your ecotourism vacation.
