Thomas Reef is the 3rd of the 4 cartographer reefs in the Strait of Tiran. The four 19th century cartographers Jackson, Woodhouse, Thomas and Gordon were forever kept in the history books by naming these four reefs in their honour.
The reef is about 400 metres north to south with strong currents running from the south and north meeting in the middle and can give the unsuspecting diver a bit of fright.
For less experienced divers, the dive will concentrate on the sandy ledge around 30 metres and the cave at 5 metres, with a sheltered area on the north, allowing easy pick-up.
For technical and more experienced diver, the sandy ledge at 30 metres is the beginning of the dive, as you will follow the ledge down until you will see a canyon open up at 40 metres. The canyon continues down and there is lovely rock bridge at 52 metres.
