Who is Denis Grosmaire?
Denis Grosmaire is a local freediving champion (360 ft) and ocean guide born in French Polynesia. Passionate about marine life and the preservation of sharks, he has spent his life exploring the Tuamotu atolls and sharing their natural and cultural treasures with visitors from around the world.

Why explore the Tuamotu Islands?
The Tuamotus are a remote paradise of turquoise lagoons, coral reefs, and wild passes where nature still reigns free. Each atoll offers a glimpse of authentic Polynesian life and exceptional marine biodiversity — a dream destination for ocean lovers, snorkelers, and adventurers seeking untouched beauty.

What can I expect to see underwater?
During the snorkeling sessions, you’ll drift through passes filled with tropical fish, rays, and reef sharks. The lagoons are alive with color and movement, and with a bit of luck, you might meet dolphins, hammerheads, or even tiger sharks.

How is life on the atolls?
Life on the Tuamotu atolls is simple, peaceful, and deeply connected to nature. The inhabitants live in harmony with the sea, following the rhythm of the tides and the trade winds — a world away from the stress of modern life.

Not at all. The expedition is open to everyone, and most activities involve snorkeling in shallow, calm waters. Denis and his team will guide you safely and share their passion for the ocean, whatever your level of experience.

When is the best time to join the expedition?
The Tuamotu Islands enjoy warm weather year-round. The best conditions for visibility and marine encounters are usually from April to November, but each season offers something unique.
