Thomas Reef

Smallest of the four Tiran reefs and, for many guides, the prettiest, Thomas concentrates its color into a tight lap: soft-coral terraces, fields of fire coral, and gorgonians leaning into the flow. Below 35 meters a canyon slices along the eastern side, spanned by natural arches and reserved in practice for technical divers - the recreational drift stays higher, riding the walls among snapper, fusiliers, and patrolling whitetips. Because the reef is short, current dictates everything; on a strong exchange the site becomes a fast scenic transit, on slack it rewards slow inspection of the overhangs. Turtles and eagle rays cross the deep edge, and the top reef glows in afternoon light.

El momento por el que vienes: Soft-coral terraces at their densest; the deep canyon and arches for qualified teams; fast, exhilarating drifts.

Topografía: Steep walls, soft-coral terraces, and a deep canyon crossed by rock arches

Corriente: Current wraps both ends of the small reef and can turn washing-machine quick; listen to the briefing.

Entrada: No moorings on the exposed faces - dives run as drifts timed to the tide.

Riesgos: Strong current and eddies; the canyon lies beyond recreational limits; separation risk on busy days.

Permisos y normas: Tiran marine-park fee applies.

Nitrox: Vale la pena aquí — los perfiles se sitúan en el rango donde el aire enriquecido (nitrox) amplía de forma significativa el tiempo sin descompresión (con la formación necesaria para usarlo).
