THE LEGACY

The original glassbottom catamaran experience

This is the original glassbottom catamaran tour out of La Parguera: a short sail to the classic bioluminescent bay that foregrounds viewing through the vessel’s glass-bottom panels.

THE PHENOMENON

Seeing dinoflagellates up close

After a brief explanation of the natural cause, passengers see the bioluminescent organisms light up around and beneath the boat through the many glass viewing areas—an intimate, surface-level encounter with the glowing bay.

THE RIDE

Stable, comfortable catamaran sailing

The operator emphasizes a safe, stable and comfortable ride—sailing past coastal beach houses with opportunities for stargazing on clear nights during the roughly 20‑minute transit to the bay.

What the day feels like

What the outing feels like

The cruise begins at the La Parguera dock and, after a short coastal run of about 20 minutes, settles in the original bioluminescent bay; a concise interpretive talk explains what causes the glow, then the glass-bottom panels turn the water beneath the boat into a living, luminous display.
