Woodhouse Reef

Tiran's longest and narrowest reef, a one-kilometre wall drift with a canyon at 25-30m, black coral colonies, and the notorious washing machine current zone.

The dive

Drop into the blue along the eastern wall and let the current carry you north. The wall falls away steeply, covered in hard and soft corals. Between 20 and 25 metres, black coral colonies appear among the growth. Further along, the canyon opens up at around 25-30 metres, fanning out into a coral garden interspersed with sand alleys. A large red anemone here hosts Red Sea anemonefish. Sea turtles glide along the wall. Schools of jackfish and fusiliers pass in the blue.

The current builds as you approach the northern end. Guides time the drift to turn the dive before the channel between Woodhouse and Jackson, where colliding currents produce the washing machine effect. Most dives end with a gradual ascent along the shallower reef crest, deploying an SMB for pickup.

What makes it special

Woodhouse occupies the middle ground among Tiran's four reefs. Jackson to the north is the busiest, Thomas is the technical diver's canyon. Woodhouse is the long, narrow one in between. Its canyon is shallower than Thomas's, sitting at 25-30 metres rather than descending past 90, which places it within recreational limits. Black coral between 20 and 25 metres adds character to the wall that other Tiran sites lack at that depth range.

The reef stretches roughly one kilometre, the longest of the four. That length means a single drift covers more reef than at any other Tiran site. Fewer boats anchor here compared to Jackson, so the fish life along the wall is less disturbed. The washing machine zone at the northern end is a genuine feature, not a mild warning. Currents there shift unpredictably and have caught experienced divers off guard.

Know before you go

Woodhouse Reef is always a drift dive. The narrow profile means no boat can shelter alongside the reef, so entries and exits happen in open water. An SMB is essential. Nitrox is worth having for the canyon sections at 25-30 metres.

The site is typically dived as part of a Tiran day trip that includes one or two other reefs. Liveaboards from Sharm and Hurghada also include Tiran in their itineraries. A Tiran Island fee of approximately EUR15 per trip applies. Summer brings the best pelagic action but also the most boats. In winter, visibility can exceed 30 metres.

The eastern wall drift is manageable for experienced divers. The northern end near the washing machine zone requires awareness of strong, unpredictable currents.

Frequently Asked Questions

What is the washing machine at Woodhouse Reef?
The washing machine is the narrow channel between Woodhouse Reef and Jackson Reef where currents from both sides of the strait collide. This creates powerful, swirling eddies that can catch divers off guard. Guides typically plan dives to end before reaching this zone, ascending to shallower water where the current is less intense.
What certification do I need to dive Woodhouse Reef?
Advanced Open Water certification is recommended. The wall drift takes divers along the eastern side at 15-25m, and the canyon sits at 25-30m. Variable currents and the exposed position in the Tiran strait mean this is not a site for newly certified divers, though competent divers with drift experience will find the main wall manageable.
How does Woodhouse Reef compare to the other Tiran reefs?
Woodhouse is the longest and narrowest of the four. Jackson to the north draws more boats and has the strongest currents. Thomas is known for its 93m canyon and dense soft corals. Gordon at the south end has the shark amphitheater and Loullia wreck. Woodhouse sits in between with its own canyon at 25-30m, black coral colonies, and a quieter atmosphere.
What marine life will I see at Woodhouse Reef?
Green sea turtles, jackfish schools, giant morays, and reef fish are commonly seen along the wall. The canyon area has black coral colonies and a large red anemone with clownfish. Whitetip and grey reef sharks appear more frequently in summer (Jul-Sep). Spotted eagle rays and occasional hammerheads are possible but not reliable.
When is the best time to dive Woodhouse Reef?
Woodhouse Reef is diveable year-round. Summer (Jul-Sep) brings the warmest water (27-29C) and the best chances for pelagic encounters including reef sharks. Winter offers the clearest visibility, sometimes exceeding 30m. Tiran day trips can be cancelled during strong north winds regardless of season.
Is Woodhouse Reef suitable for underwater photography?
Yes. The canyon area on the eastern side has a large red anemone specimen described as a photographer's dream. Black coral colonies between 20-25m and the diverse reef wall provide additional subjects. Visibility of 20-30m gives good shooting conditions. Nitrox extends bottom time for longer shoots at depth.
What happened when a cargo ship hit Woodhouse Reef?
On December 31, 2009, the 260m container ship CSCL Hamburg ran aground on the western side of Woodhouse Reef. The incident prompted concern about damage to reef overhangs where baby whitetip reef sharks had been observed. The western side is rarely dived since boats cannot shelter alongside the narrow reef.
