Strange Places: The Pitch Lake of Trinidad

The world’s largest natural deposit of asphalt

Introduction

Hidden in the southwest of Trinidad lies one of the strangest natural phenomena on Earth — the Pitch Lake. Unlike ordinary lakes filled with water, this vast, surreal landscape is composed of thick, black asphalt that slowly bubbles and shifts beneath your feet.

What is Pitch Lake?

Pitch Lake is the largest natural deposit of asphalt in the world, covering approximately 100 acres near the town of La Brea. The surface appears solid, but it is actually semi-liquid, constantly moving and reshaping itself over time.

Fun Fact: The lake is so dense that you can walk across it — but in some areas, your shoes may slowly sink!

How Was It Formed?

Scientists believe that Pitch Lake formed due to the collision of tectonic plates beneath the Caribbean. Oil deposits deep underground are forced upward through cracks in the Earth’s crust, where lighter elements evaporate, leaving behind thick asphalt.

A Living, Moving Landscape

The surface of the lake is constantly in motion. Pools of water collect in depressions, small islands of vegetation form, and bubbles of gas occasionally rise and burst. Objects that fall into the lake can disappear and re-emerge years later due to the slow churning of the asphalt.

Historical Significance

Pitch Lake has been used for centuries. Indigenous peoples waterproofed their canoes with its asphalt, and in the 19th century, it became a major source of commercial asphalt exported worldwide.

Visiting Pitch Lake

Today, visitors can tour the lake with local guides, learning about its geology and history while walking across its unusual surface. The surrounding area offers a glimpse into both industrial use and natural wonder.

Why It’s So Strange

Few places on Earth blur the line between solid and liquid quite like Pitch Lake. It’s a place where the ground moves, breathes, and even swallows objects — making it one of the most bizarre landscapes you can explore.
