St John’s Reef: The Ultimate Guide to Egypt’s Coral Wonderland
St John’s Reef (Rocky Island’s neighbour in Egypt’s far south) is a sprawling complex of reefs, pinnacles and coral gardens near the Sudanese border. It is the jewel of the Deep South — remote, pristine and bursting with colour — and it delivers some of the healthiest hard coral and richest reef life anywhere in the Red Sea. This guide covers its standout sites, marine life, conditions and how to dive it.
Why the Deep South is different
Because St John’s is so far from major resorts, its reefs see far fewer divers and remain exceptionally healthy. The area is a maze of coral heads, caverns and shallow gardens interspersed with deeper pinnacles, offering everything from gentle, sun-dappled snorkel-depth coral to adrenaline-filled offshore walls. It is a photographer’s paradise and a favourite of experienced divers looking for unspoilt reef.
Signature sites
- St John’s Caves (Habili Ali & the cave system) — a magical labyrinth of caverns and swim-throughs where sunlight streams through the coral in shafts.
- Habili Ali & Habili Gaffar — offshore pinnacles draped in soft coral and gorgonians, with sharks and pelagics in the current.
- Gota Kebir & Gota Soraya — large reefs with plateaus, walls and the chance of grey reef sharks.
- Umm Khararim — shallow coral gardens ideal for relaxed dives and superb macro life.
Marine life
St John’s combines big and small: schooling snapper, fusiliers and barracuda, napoleon wrasse and turtles on the reefs, grey reef and whitetip sharks around the offshore pinnacles, and outstanding macro life — nudibranchs, anthias and anemonefish — in the coral gardens. The hard-coral cover here is among the best you will see.
Conditions and experience level
The sheltered coral gardens suit most certified divers, while the offshore pinnacles (Habili Ali, Habili Gaffar) are current-swept and better suited to advanced divers. Because the region is remote, trips are run as liveaboards and a comfortable level of experience makes the deeper, exposed sites far more enjoyable.
