The Bells

Shore-entry chimney north of Dahab's Blue Hole: a vertical crack drops to 26-30m onto a Red Sea wall of soft corals and fans, drifting south to the Blue Hole saddle at 7m.

The dive

The Bells starts as a gap in the reef table — a narrow crack barely wide enough to descend into. Drop in one at a time; the chimney is vertical, close on both sides, and as your tank taps the rock walls it produces the ringing that names the site. At 26 to 30 metres, the walls part. The reef drops away into open blue and a sheer wall takes over, draped in soft corals and sea fans from top to base. Clownfish dot the anemones. Anthias hover in shoals. A gentle south-running current carries you down the wall without effort, depth stable, the blue expanding to the left while the wall holds colour to the right. After 20 to 30 minutes on the wall, the coral saddle at 7 metres comes up ahead — a dense shelf where you cross into the Blue Hole sinkhole for the safety stop. The dive ends where the famous landmark begins. Avg duration is around 45 minutes.

Depth discipline matters here. The dive opens at maximum recreational depth and stays there while the most interesting section of wall unspools below you. Monitoring the computer and watching air consumption is active work, not background noise. Surface finning back against any residual current is tiring — leaving enough gas to surface comfortably and signal with an SMB is not optional.

What makes it special

The Bells is the entry that transforms the Blue Hole from a sinkhole into a wall dive. Arriving at the Blue Hole by walking down from the cafes and stepping in at the saddle is one experience. Arriving from depth, having just drifted 300 metres of sheer Red Sea reef wall, is entirely different. The chimney is what makes the route: it forces a direct vertical drop to depth, the acoustic resonance is memorable, and the moment the walls open onto open blue is as abrupt a scene change as diving offers.

The wall itself is legitimate Red Sea reef — not the approach to something else, but a dive worth having on its own terms. The soft coral and sea fan coverage from chimney base to saddle holds its own against Dahab's other walls. What it is not is a beginner site wearing accessible clothes: the entry requires controlled buoyancy in an overhead environment, the profile goes deep before it comes shallow, and the Blue Hole's reputation for attracting divers who misjudge their limits is not confined to the Arch. Both sites reward the diver who shows up with the right certification and reads the briefing.

Know before you go

Arrive early. The Blue Hole car park fills with day-trip buses from Sharm from around 10am, and the chimney entry becomes congested when groups queue for it. A morning dive on opening gives you a quieter chimney, emptier wall, and a saddle crossing without crowd pressure.

The walk from the car park to the entry crosses rocky, irregular ground — 150 metres that feels longer in booties and a BCD loaded with a full tank. Operators can carry equipment to the entry point if you ask. National park entry for the Blue Hole area runs approximately 20 USD for foreign visitors, with the car adding another fee if you drive in. Rates shift; confirm with your operator before arrival.

The salinity of the Gulf of Aqaba is higher than most divers are calibrated to — around 41 parts per thousand versus standard ocean at 35. Add lead before assuming your usual setup. A torch is useful in the chimney; the walls carry crevices with small marine life that repays a look on the way down.

Why Dive The Bells

What makes this dive site stand out.

  1. 1
    Chimney entry

    Narrow vertical crack; tank contact with the walls produces the bell-tone ringing that names the site

  2. 2
    Red Sea wall at 26-30m

    Sheer drop draped in soft corals, sea fans, and sponges opening below the chimney

  3. 3
    Bells-to-Blue Hole route

    Standard route drifts south along the wall and arrives at the Blue Hole saddle at 7m

  4. 4
    Shore entry no boat

    150m walk north of the Blue Hole car park; no boat required, kit-carry across rocky ground

  5. 5
    Depth control critical

    Dive starts at 26-30m before ascending; AOW minimum, air monitoring essential on the wall

Frequently Asked Questions

Is The Bells a separate dive from the Blue Hole?
They are two distinct sites usually dived as a single dive. You enter at The Bells, descend the chimney to 26-30m, drift south along the reef wall for 20-30 minutes, and arrive at the Blue Hole coral saddle at 7m for the safety stop and exit. The Blue Hole itself — the famous sinkhole — is the arrival point, not the dive.
Why is it called The Bells?
The name comes from the chimney entry: when divers descend the narrow vertical crack, their tanks knock against the rock walls and produce a distinctive bell-like ringing. The sound is consistent enough that it named the site.
What certification do I need?
Advanced Open Water at minimum. The chimney exits at 26-30m, which exceeds the 18m Open Water limit. Several dive review accounts note divers attempting this on OW certification — that is a depth violation. A guide is strongly recommended for first-timers regardless of certification level.
How physically demanding is the shore entry?
The walk from the Blue Hole car park to the chimney entry is around 150 metres over rocky, uneven ground in full dive kit. Ankle health matters. Dive operators can carry equipment and assist with kitting up at the entry. The water entry itself is straightforward once you reach the crack.
What is the water temperature at The Bells?
The Gulf of Aqaba runs 29-30°C surface in summer, dropping to 20-22°C in winter. A 3mm shorty suits summer; a 5mm full suit covers winter. Note that the Gulf of Aqaba is markedly saltier than open ocean — around 41 parts per thousand — so you may need more weight than you're used to.
When should I go?
The site is diveable year-round. March to June and September to December are the consistent choices. Autumn — September through mid-November — is particularly favoured: the water holds summer warmth, crowds thin from peak, and visibility runs well. Summer is hottest and warmest but the Blue Hole area gets heavy day-trip traffic by mid-morning.
Do I need a guide for The Bells?
Strongly recommended for first-timers. The route involves three distinct phases — chimney descent, wall drift, and saddle crossing into the Blue Hole — that require confident navigation. Most operators run a maximum of six divers per guide. Going early in the morning also means less congestion at the chimney and saddle crossing.
