Thomas Reef

The smallest of the four Tiran reefs but the richest in soft coral. Its signature feature is the Three Thomas Arches, a series of deep archways beyond 35m that are a technical dive in their own right. The recreational route drifts the plateau and wall in strong current, with dense soft-coral growth and reef fish concentrated on the current-facing side.
