Scuba Diving in San Salvador

Diving in San Salvador is wall diving, and the wall is absurdly close. San Salvador is the exposed peak of a submerged mountain sitting on its own isolated carbonate platform, outside the Caribbean proper, in the open Atlantic. There's no broad shelf to cross. The reef crest sits at just 35 to 45 ft, and then the seabed drops away toward 15,000 ft. Riding Rock puts most of its sites inside a twenty minute boat ride. Runway 10 is three minutes out. Telephone Pole is five. A few of the marquee dives sit further along the coast, though: Great Cut is twenty-five minutes, Doolittle's Grotto thirty, and La Crevasse a full fifty.

The visibility here is the stuff of legend and it mostly holds up. Independent accounts put the average above 100 ft, and 150 ft turns up on a good day (the Bahamas tourism board will tell you 150 ft is the norm, but no independent source goes that far). Combine that with the island's isolation and its position in the path of the Antilles Current, and you get something rare: a realistic shot at a scalloped hammerhead on an ordinary reef dive, with no bait in the water. Riding Rock's Guanahani Divers states plainly that it doesn't use a bait box and doesn't have divers kneel in a circle, and no baited shark dive operates on the island. Sharks here come because they want to.

The wall isn't a flat face. It's fissured and cavernous, cut with keyhole tunnels, crevices and coral ridges that have calved off and now run parallel to the wall. At Doolittle's Grotto you descend through the reef rather than over it, dropping through tunnels into a sand valley at 120 ft. At Great Cut you swim through a keyhole tunnel and see blue water on the other side before you enter it.

Caribbean reef sharks are the everyday animal, and the local operator says it isn't unusual to dive with a dozen or more. The scalloped hammerheads are the November-to-May bonus, and they're opportunistic, not guaranteed. Be honest with yourself about that before you book: there's no baited hammerhead dive on this island.

Two operators currently run the diving, one a dedicated dive lodge that's open year-round, the other the dive centre at an all-inclusive resort that closes seasonally. Both work the same walls. The dive centre at the resort has changed hands in recent years, so confirm who you're actually booking with when you commit.

Best dive sites in San Salvador

Doolittle's Grotto

The dive that shows you what San Salvador's wall is actually made of. Two parallel coral ridges, each over 50 ft thick, riddled with tunnels. You don't swim over the wall here, you descend through it.

The near ridge has four tunnels dropping into a sand valley. The outer ridge is split by two big crevices that spit you out at 120 ft. The guide's route is usually in through the south tunnel, out along the crevice into the deep valley, right at 120 ft, then back up through the second crevice to 80 ft and home through a tunnel. A school of horse-eye jacks stays with you for most of it, and giant barrel sponges mark the ridges. Usually run as the first dive of the day, and it's a thirty minute ride out.

Depth: 30–140 ft (9–43 m); the sand valley bottoms at 120 ft (37 m) | Level: Advanced

Great Cut

A whole slab of the wall has calved off and now runs parallel to it, about 50 ft away, forming a 250 ft ridge that tops out at 60 ft. Halfway along, a keyhole-shaped tunnel punches straight through to the open ocean, and you can see blue water through it before you commit.

The guide's tell for finding the entrance: look for several hanging rope sponges at 85 ft. Huge elephant ear sponges cover the north end, and schools of grunts sit on the ridge top. Twenty-five minutes from the marina, so it's one of the longer rides on the island, though not the longest.

Depth: 40–150 ft (12–46 m); tunnel top at 95 ft (29 m) | Level: Advanced

Shark Alley

A shark site that works without bait. A 200 ft ridge of big coral heads runs parallel to the wall, penetrated by coral tunnels that lead out over the drop-off. Sharks show up off in the deep or cruising the 80 ft plateau, which is exactly what the operator promises and no more.

Caribbean reef sharks are the reliable animal here. Island-wide, Riding Rock says it isn't unusual to dive with a dozen sharks or more, though that's a general claim rather than a Shark Alley one. What makes the site different from Nassau or Tiger Beach is what's missing: no bait box, no kneeling circle, no feeder. You dive the wall and the sharks decide.

Depth: 45–120 ft (14–37 m) | Level: Advanced for the deeper plateaus

Telephone Pole

The easiest of the marquee dives, and home to the island's most-published piece of coral: a huge purple gorgonian on the northern edge of the cut that has been shot for magazine articles since 1974. (If you want the site the pros actually use for models and product work, that's Snapshot.) The crevice runs from a 35 ft sand flat down to 100 ft at the wall edge. The wall then runs sheer for about 200 ft before breaking into coral heads.

It's named for a telephone pole that was once wedged across the crevice, until storm surge snapped it in half and flushed it down the chute. The crevice tops out shallow, so you pick your own depth here, which makes it one of the few signature sites genuinely open to Open Water divers. Usually the second dive of the morning.

Depth: 35–100 ft (11–30 m) | Level: All Levels (you choose your depth)

Devil's Claw

Named from what it looks like from above: three crevices splayed out like fingers, with a free-standing coral head offshore as the heel of the paw. It's a true double-drop wall, falling from 45 ft to 80 ft, then again from around 100 ft to 150 ft, and then out to the deep cliff.

Big animals work both plateaus, so this is one of the better sharking sites on the island. Two small pillar coral colonies mark the ends of the crevices, and quillfin blennies are reliably recorded at the bottom. Fifteen minutes from the marina.

Depth: 45–150 ft (14–46 m) | Level: Advanced for the deeper plateau; Open Water can stay on the 45 ft hardpan

Best time to dive San Salvador

The best time to dive San Salvador is November through May, which is the dry season and, more importantly, the shark season.

The trade-off is clean. Winter gives you the sharks and the calmest seas on the lee side, but the coolest water and the occasional front putting chop on the exposed southern sites. Summer gives you warm water and flat seas but the fewest hammerheads. Come in winter if the sharks are the point.

Hurricane season runs June 1 to November 30, peaking August through October, and San Salvador is a small remote island with one airport. A named storm means real evacuation and cancellation risk. Insurance matters here.

Diving conditions in San Salvador

Diving conditions in San Salvador are close to ideal, and the visibility is the reason the island has the reputation it does.

The reef system is what makes everything else possible. San Salvador sits on its own isolated carbonate platform in the open Atlantic, so there's no broad shelf. The reef crest sits at 35 to 45 ft just offshore and the wall drops from there, falling to 110 to 160 ft to a sloping ledge, then over a second vertical cliff into thousands of feet. There are 35-plus moored sites, and many sit inside the San Salvador National Parks.

Marine life in San Salvador

Marine life in San Salvador is defined by two things: exposure to the open Atlantic, and the absence of bait. The animals that turn up here are passing through on their own terms, and the Bahamas Shark Sanctuary, declared in 2011 across roughly 243,000 sq mi (630,000 sq km), is why they're still passing through at all.

Scalloped hammerhead (Sphyrna lewini): November to May, out over the deep ledges, with Runway 10 the one site an operator names

The headline animal, and San Salvador is one of very few places on Earth where a scalloped hammerhead can show up on an ordinary reef dive. Sightings are opportunistic, out over the deep ledges, and there is no baited hammerhead dive here. Come hopeful, not entitled.

Caribbean reef shark (Carcharhinus perezi): year-round, on the walls and plateaus

The reliable, everyday shark. Riding Rock says it isn't unusual to dive with a dozen or more, and they come in without any bait in the water.

• Nassau grouper (Epinephelus striatus): Critically Endangered, and famously tame and curious on San Salvador.
• Southern stingray (Hypanus americanus): big individuals on the sand flats at Telephone Pole.
• Winter and spring visitors: bull shark, silky shark, oceanic whitetip and the occasional tiger shark. Dolphins investigate boats and divers, and eagle rays appear out of the blue on the walls.
• Reef and resident life: horse-eye jack, mutton snapper, ocean and queen triggerfish, grunts, goatfish, squirrelfish, rare hamlets, quillfin blenny, yellowhead jawfish, yellow stingray, queen conch, green, hawksbill and leatherback turtles, seahorses. Night dives bring out basket starfish, octopus and nudibranchs.
• Corals and sponges: black coral trees, pillar coral, elephant ear sponges, giant barrel sponges, a landmark purple gorgonian, bluebell tunicates.

Five marine protected areas created in 2015 are now formally approved as the San Salvador National Parks, and many of the moored dive sites fall inside them. The Gerace Research Centre on the island's north side runs marine science and coral restoration programmes, and Vicky's Reef is an active long-term reef monitoring plot, so you'll see the local field station's coloured markers on the wall top. Don't touch them. One dive centre partners with the Perry Institute for Marine Science and the Reef Rescue Network and runs coral nurseries you can dive.

Practical information

Dive prices

Neither operator sells a classic two-tank, so build the number honestly. At the resort dive centre, single dives run about $97 unguided with your own gear up to $117 guided with rentals, and nitrox is included, so a two-tank equivalent is roughly $194 to $234. Packages bring that down: ten dives run $840 to $1,040.

The dive lodge sells diving inside all-inclusive packages rather than à la carte. A week with 16 dives, all meals, room, transfers and taxes runs around $2,184 per person double occupancy. Extra boat dives are $50, but only when at least six divers want to go, so don't bank on topping up your day solo. The diving itself is fairly priced. The trip is expensive because there's no cheap way onto this island and only two operations, both bundled into resorts. Call it $$$.

Getting there

One airport: San Salvador (ZSA) at Cockburn Town, an official port of entry. The workhorse route is the daily Bahamasair flight from Nassau. There's also a direct Bahamasair service from Miami that runs once a week, typically on Saturdays, where you clear Bahamian customs on arrival and US customs in Miami on the way back. Schedules for that single weekly rotation have shifted before, and PADI's own page describes a Fort Lauderdale charter instead, so confirm the day when you book rather than assuming Saturday. Resort charters run from Miami and, seasonally, from Montreal. San Salvador is 385 miles southeast of Fort Lauderdale.

Recompression and medical cover

Take this one seriously, because the island's medical picture is thinner than the marketing suggests. Only Blue Diving, the dive centre at Club Med Columbus Isle, states on its own website that a hyperbaric chamber is present on the Club Med premises and a dive doctor is on hand at all times. That claim could not be independently confirmed. The SSS Recompression Chamber Network, which runs the region's chambers, lists exactly one Bahamian facility, the Bahamas Hyperbaric Centre at Lyford Cay in Nassau. Club Med's own official Columbus Isle factsheet makes no mention of a chamber, a dive doctor or any on-site medical facility.

Plan on the basis that the nearest independently documented recompression chamber is in Nassau, an air evacuation away. Carry dive accident insurance that covers evacuation, dive conservatively on a wall this deep, and take the nitrox. If the on-site chamber matters to your risk planning, ask the operator for written confirmation before you book, and note that the resort historically closes around September and October in any case.
