Egypt
The Sinai desert drops into the Red Sea here, mangroves clinging to the last ledge.
The desert ends abruptly. One moment you are driving through flat, wind-scoured Sinai scrub; the next, sandstone cliffs drop into water that shifts from turquoise to ink-blue within metres. Below the surface the coral walls plunge toward the meeting of two gulfs, and the current brings everything sweeping past.
Ras Mohammed occupies the southern tip of Sinai, established in 1983 as Egypt's first marine protected area. Shark and Yolanda reefs drop in sheer coral walls to over 700 metres, and the upwellings where the Gulf of Suez meets the Gulf of Aqaba feed more than 200 coral species and around 1,000 species of fish — clouds of orange anthias, unicornfish in their thousands, barracuda schooling in tornado columns. On land the park protects mangrove stands rooted in tidal channels at the desert's edge, salt-tolerant trees growing out of bare rock.
Friends
Fill a dive boat between you — Shark and Yolanda in the morning, barracuda stories over Sharm seafood by night.
Lunch comes on the dive boat between tanks — the park itself stays restaurant-free.
Back in Sharm the post-dive table is seafood: grilled prawns on a terrace while the day's dives get retold.
