Dive Site Highlights: “The Dome” in Turks & Caicos


Located off the coast of Providenciales in Turks & Caicos, “The Dome,” also known as “The Thunderdome,” is a unique dive site with a fascinating backstory and vibrant marine life. This artificial reef has become a favorite among divers, offering an intriguing blend of history and underwater beauty.

History of The Thunderdome

In the early 1990s, a French game show called “Le Trésor de Pago Pago” was filmed in Turks & Caicos. The game show featured a number of challenges for contestants, including free diving 30 feet of water (10m) into a steel-framed dome structure. While inside, contestants collected as many pearls in a set time while “Mermaids” (scuba divers) offered assistance with their spare regulators to trade a breath for a pearl. However, the show’s concept was flawed due to the dangers of lung overexpansion injuries and air embolisms caused by divers taking breaths at depth and then ascending. These risks quickly ended the game show, but the remnants of the dome created an accidental artificial reef, now teeming with marine life. Watch a clip from “Le Trésor de Pago Pago” below.

Dive Experience

Today, the collapsed structure of The Dome is covered in vibrant brain corals, colorful sponges, and home to various species like blennies, schooling grunts, snappers and other colorful reef fish seeking shelter. Divers can explore the remains of the dome, appreciating how nature has reclaimed the man-made structure.

Aside from The Dome, the dive site includes an impressive wall and a feature known as “The Chimney.” By swimming west from the mooring, divers reach the wall and can find a vertical cut called The Chimney, where they can ascend through a narrow passage, watching bubbles rise like smoke.
