Hi, Your question is quite clear, if you are asking about the Pitch Lake that the English Captain Sir Walter Raleigh happened upon, and used it's product to seal off leaks in his ship in 1595.
The Pitch Lake is the main attraction, since Trinidad is not really geared up for tourism unlike the sister island Tobago which I would recommend due to its world class beaches, reefs,bays and a natural 4 foot pool surrounded by the ocean.
The Pitch Lake is the largest natural deposit of asphalt in the world, located at La Brea in southwest Trinidad, within the Siparia Regional Corporation. The lake covers about 40 ha and is reported to be 75 m deep.Some streets in New York and Germany have been paved with asphalt from this lake.
The Pitch Lake is a tourist attraction that attracts about 20,000 visitors annually. It is also mined for asphalt by Lake Asphalt of Trinidad and Tobago.
