Parque Nacional Yasuní

This vast tract of protected rainforest contains a simply dazzling biodiversity matched almost nowhere else on earth. Excitement-filled canoe trips through tiny overgrown creeks and hikes across the jungle floor with experienced guides reveal all manner of flowers, plants and creatures, many of which you will not even have heard of before, let alone have seen in real life, while several populations of indigenous peoples continue to resist contact with the outside world here. This natural wonder remains, at present, unspoiled (oil rights have been sold, unfortunately).
