Trinidad's ecology is possible a little more diverse than Tobago, and just as beautiful to visit. Things like the La Brea Pitch Lake, which occurs naturally. It is a lake of pitch, which is the stuff we used on our roads etc. Mud Volcanoes, Caroni and Nariva Swamps, the Oropuche Lagoon, the mountain ranges of the island, Lapinot Caves and finally Asa Wright Centre, have varied and diversity plant and animal life.
